Whether you shop at a franchise dealer, a used-car lot, or buy from a private seller, the numbers on your contract depend on how you buy, what reduces tax, and whether you finance taxes and fees. We walk through each piece with real dollar examples so you can sanity-check any calculator or dealer worksheet before you sign.
If you have already used a North Dakota auto loan calculator online, this article shows exactly what should happen behind those numbers—and which inputs must come from you because no government agency publishes them.
What Makes North Dakota Different
North Dakota vehicle taxation is not interchangeable with other states. | Input | Official default | Notes | A responsible calculator uses government defaults only—never industry survey averages for doc fees, credit-tier APR tables, or expired tax rates.
Important: This guide reflects official sources as of August 2026. Rates and fees change when legislatures act or agencies update schedules. Confirm final amounts with your lender and motor vehicle agency before signing.
Do not treat Georgia Title Ad Valorem Tax (TAVT) rules as if they applied in North Dakota. Each state has its own statute for how vehicle transfers are taxed.
Official North Dakota Fees and Tax Defaults (2026)
Some costs are fixed by statute or published on the state motor vehicle fee schedule. A compliant North Dakota auto loan calculator should prefill these—not averages from car-shopping websites.
| Input | Official default | Notes |
|---|---|---|
| Motor vehicle excise tax | 5.0% of purchase price (sales price − trade-in − qualifying rebate) | NDCC § 57-40.3-02; Tax Commissioner. Instead of state/local sales tax. No local add-on. |
| Title | $5 | NDDOT SFN 2872 (4-2026). |
| Abandoned-vehicle disposal | $1.50 | First ND title on new and out-of-state passengers, trucks, buses, motor homes — SFN 2872. |
| Passenger license (2026) | Weight / year-first-registered schedule | NDDOT 2026 Passenger Fee Schedule (1 Jan–31 Dec 2026). Example: 2021-and-newer, 3,200–4,499 lbs = $93/12 months. User-enter weight. Fees are based on year first registered, not model year. |
| Plate / credit transfer | $5 | SFN 2872. |
| Lemon Law | No separate titling fee | NDCC ch. 51-07 (remedy statute). |
| EV / PHEV extra (2026) | $120 EV / $50 PHEV | Same 2026 passenger schedule (“Additional Annual Fees for Electric/Plug-In Hybrid Vehicles”). Conventional hybrids: no extra on that line. |
| Doc fee | No statutory cap | Title, registration, license, and document fees are not in the excise base (Tax Commissioner guideline GL-21963). Default $0. |
| APR | 7.14% (60-month new-car bank) | Fed G.19, Q2 2026. No official used-car APR. |
| Vehicle price, down, trade, rebate, GAP, warranty, branch fee | User entered | No official average price. Branch fee on SFN 2872 is location-specific — user-entered. |
| Term | User entered; 60 is a reasonable chip because G.19 publishes a 60-month series | Do not treat 84 as official. |
| Credit-score presets | None | No official government APR-by-FICO table. |
Vehicle price, down payment, trade-in value, manufacturer rebates, GAP insurance, extended warranties, and optional add-ons are never official defaults. You enter those. Similarly, there is no official government used-car APR series—only the Federal Reserve’s new-car bank benchmarks discussed below.

Understanding Purchase Channels in North Dakota
How you buy the vehicle changes which tax base rules apply. Dealers typically collect tax at the point of sale for residents; private-party buyers often pay at the motor vehicle office. Out-of-state purchases may trigger credit or use-tax rules depending on how long you owned the car before moving to North Dakota.
When you use a North Dakota auto loan calculator, select the purchase channel that matches your deal. If you are unsure, ask the seller whether tax will be collected on the contract or at registration—then mirror that choice in the calculator’s roll-tax options.
Example 1: Dealer purchase with documented trade-in
Scenario: You buy a $28,000 sedan from a North Dakota dealer and trade a vehicle the dealer will resell. Your trade allowance is $5,000.
Selling price: $28,000 Trade-in allowance: − $5,000 ───────────────────────────── Taxable base: $23,000 (Apply North Dakota official rate to $23,000 per statute)
Your cash down payment does not reduce the taxable base in most states. It only changes how much you borrow after tax and fees are computed.
Example 2: Private-party purchase
Scenario: You pay a private seller $14,000 for a used car. There is no dealer to collect tax on the contract.
Reported purchase price: $14,000 Trade-in on private sale: Often $0 credit (state-specific) Tax: Paid at title/registration per North Dakota law Title & registration: Paid to motor vehicle agency
Private-party buyers should budget for tax and title fees at the DMV even if the seller only asks for the agreed purchase price on day one.
Benchmark Auto Loan Rates (Federal Reserve)
There is no North Dakota statewide official APR series. The official U.S. series is the Federal Reserve G.19 Consumer Credit release (Regulation Z APRs). Current release, 7 Aug 2026 (June / Q2 2026 data).
Bank rates are unweighted averages of each bank’s most common rate in the first calendar week of the middle month of the quarter — not origination-weighted, not North Dakota-specific.
| Series | Rate | Period |
|---|---|---|
| Commercial-bank 60-month new-car | 7.14% | Q2 2026 |
| Commercial-bank 72-month new-car | 6.97% | Q2 2026 |
| Finance-company new-car (amount-weighted) | 6.1% (Q1) / 6.08% (Mar 2026, FRED RIELPCFANNM) | 2026 |
Do not treat the 72-month bank print sitting below 60-month as “longer terms are cheaper.”
Used cars: G.19 does not publish a used-car APR. Default used APR = blank / user-entered.
Context (official, not a calculator default): effective federal funds 3.63% (H.15, 21–27 Aug 2026); bank prime 6.75%.
Calculator APR behavior: amortize at the user’s rate. Prefill 7.14% only as the G.19 60-month new-car bank average. Disclose: *estimate, not a TILA quote or a lender offer.*

How North Dakota Vehicle Tax and Fees Work
Motor vehicle excise tax — 5%, not sales tax, no local
Licensed motor vehicles (including trailers/semi-trailers required to be registered) pay motor vehicle excise tax instead of state and local sales tax — ND Tax Commissioner; NDCC ch. 57-40.3.
- Rate: 5% of purchase price (or FMV if not acquired by purchase) — NDCC § 57-40.3-02; Tax Commissioner Special Taxes.
- Collected by NDDOT Motor Vehicle as agent for the Tax Commissioner.
- No local tax on the transfer.
- Reciprocal credit for excise/sales/use tax paid in another state only if that state allows a similar credit — NDCC § 57-40.3-09; NDAC 81-05.1-01.
Official tools (link; do not scrape): NDDOT Motor Vehicle; SFN 2872; Tax Commissioner Motor Vehicle Excise Tax Guideline GL-21963.
How purchase price is computed
| Channel | Official purchase price | Trade-in reduces excise? | Manufacturer rebate |
|---|---|---|---|
| Dealer new or used | Total selling price including accessories, dealer prep, freight, and delivery, less qualified discounts (auction fee, manufacturer rebate, trade-in) — GL-21963; SFN 2872 | Yes (year, make, VIN of trade required) | Yes (line is “Full Purchase Price (less Rebate)”) |
| Private-party / gift / other | Purchase price, or fair market value if not acquired by purchase. NDDOT may use an industry guide (SFN 2872 note) | Trade-in if actually allowed on the purchase | Typically no |
| New resident | 5% of applicable price/FMV, minus reciprocal credit if the other state reciprocates | Typical pattern is a car already owned | n/a |
In the 5% base: accessories, dealer prep, freight, delivery. Out: title, registration, license, and document fees (GL-21963).
Cash down does not reduce excise. A 2025 bill (HB 1484) proposing a $100 flat tax on 10-year-old vehicles is not used unless it is the current NDCC text; the Tax Commissioner page and SFN 2872 (4-2026) still print 5%.
Do not add ND state/local sales tax on a titled highway vehicle. Do not use Georgia TAVT.
Official title, tag, lemon, EV
| Item | Amount | Source |
|---|---|---|
| Title | $5 | SFN 2872 (4-2026) |
| Abandoned vehicle disposal (new / out-of-state first ND title) | $1.50 | SFN 2872 |
| Passenger license, 2021-and-newer, 3,200–4,499 lbs, 12 months | $93 | NDDOT 2026 passenger schedule |
| Same, 3,199 or less | $73 | Same |
| Same, 4,500–4,999 | $111 | Same |
| Plate or credit transfer | $5 | SFN 2872 |
| Duplicate plate | $5 | SFN 2872 |
| EV road-use extra (2026) | $120 | 2026 passenger/pickup schedules |
| PHEV extra (2026) | $50 | Same |
| Lemon Law add-on | None | NDCC ch. 51-07 |
| Documentary / dealer doc fee | No statutory cap; out of the excise base | GL-21963. Default $0. |
Omitted on purpose: branch fees, average doc fee. User-entered, default $0.
Leases: if leased ≥ 1 year and weight < 10,000 lbs, 5% is on lease consideration; other leases are taxed on purchase price (Tax Commissioner).

Interest Rates: What the Government Actually Publishes
North Dakota does not publish an official statewide auto loan APR. The closest government benchmark is the Federal Reserve’s G.19 Consumer Credit release (Regulation Z APRs for new-car loans).
As of the August 7, 2026 release (Q2 2026 / June data):
| Series | Rate | Period |
|---|---|---|
| Commercial bank 60-month new car | 7.14% | Q2 2026 |
| Commercial bank 72-month new car | 6.97% | Q2 2026 |
| Finance company new car (amount-weighted) | 6.08% | Mar 2026 (FRED) |
These are not your guaranteed rate. Bank figures are unweighted averages of each bank’s most common quoted rate in a specific week—not weighted by loan volume, and not North Dakota-specific.
Important: G.19 does not publish a used-car APR. There is no official government “used car rate” to prefill. Enter your lender’s quote. A calculator may show 7.14% only as an illustration labeled as the new-car bank average—not as a promise of your rate.
Do not assume longer terms are cheaper just because the 72-month bank average (6.97%) prints below the 60-month average (7.14%). The Fed explains that reflects which rate each bank quotes most often, not a mathematical term premium.

How Loan Payments Are Calculated
Treat the entered rate as a nominal annual rate, compounded monthly. Monthly rate \(i = \text{rate}/12\). For amount financed \(P\) over \(n\) months:
\[ M = P \times \frac{i\,(1+i)^{n}}{(1+i)^{n}-1} \]
If \(i = 0\), \(M = P/n\). Round \(M\) to cents (ROUND_HALF_UP); last payment clears the residual. Totals from the schedule.
Amount financed ≈ (price − down − trade + trade payoff − rebate) + rolled excise/fees/doc + financed GAP/warranty. Cash due ≈ down + any excise/fees/doc not rolled. Cash down does not change excise.
This is an estimate, not a Regulation Z APR solution.
—
Amount financed is approximately: vehicle price (plus taxable doc fees where applicable), minus down payment, trade-in, and rebates (per state rules), plus trade payoff if you owe more than the trade is worth, plus rolled taxes and title/registration fees, plus financed GAP or warranty.
Cash due at signing is approximately your down payment plus any tax and fees you pay upfront instead of financing.
Rolling tax into the loan does not change the tax owed—it changes when you pay it and how much interest you pay over the life of the loan.
Important: Any online estimate is not a Truth in Lending (Regulation Z) disclosure and is not a lender offer. Your bank’s contract controls the final payment, fees, and APR.
Official Worked Examples
The examples below use the same assumptions as the official North Dakota fact brief: $38,000 vehicle price, $3,800 down, no trade or rebate unless noted, Fed G.19 60-month bank APR 7.14%, 60-month term, and taxes/fees rolled unless Example B says otherwise.
Example A — Excise + title + tag rolled
Scenario: Price $38,000, down $3,800. Excise = 0.05 × 38,000 = $1,900. Amount financed \(P\) = 38,000 − 3,800 + 1,900 + 5 + 1.50 + 93 = $36,199.50. | | Amount | |—|—:| | Monthly payment | $719.19 | | Cash due | $3,800 | | Total of payments | $43,151.19 | | Total interest |
Price $38,000, down $3,800.
Excise = 0.05 × 38,000 = $1,900.
Amount financed \(P\) = 38,000 − 3,800 + 1,900 + 5 + 1.50 + 93 = $36,199.50.
Example B — Same deal, excise + fees cash
Scenario: \(P\) = 38,000 − 3,800 = $34,200. Excise $1,900 + $5 + $1.50 + $93 paid at signing. | | Amount | |—|—:| | Monthly payment | $679.46 | | Cash due | $5,799.50 | | Total of payments | $40,767.75 | | Total interest | $6,567.75 | Rolling costs $383.94 extra interest vs cash,
\(P\) = 38,000 − 3,800 = $34,200. Excise $1,900 + $5 + $1.50 + $93 paid at signing.
Rolling costs $383.94 extra interest vs cash, and $1,999.50 less cash at signing.
Example C — Dealer used with trade
Scenario: No official used APR.
Price $18,500, trade $3,000 (VIN on SFN 2872).
Excise = 0.05 × (18,500 − 3,000) = $775. Doc fees stay out of the $775.
Example D — Private party
Scenario: —
Same $18,500. If it is a purchase, 5% of purchase price unless NDDOT applies FMV from a guide. A $3,000 “trade” reduces only if it is a true trade-in on the purchase. Typically cash at Motor Vehicle plus $5 + $1.50 + license.
Planning Cash Due vs Monthly Payment
Two numbers matter at signing: cash due and monthly payment. They move in opposite directions when you roll taxes and fees into the loan. Financing $2,500 of tax at 7.14% over 60 months adds roughly $50 per month in payment—but keeps that $2,500 out of your wallet on day one.
Neither choice changes the tax owed to North Dakota. It only changes how much interest you pay over time. Compare both structures using the official worked examples above before you decide at the dealer finance office.
Example: Rolling $2,000 of fees vs paying cash
If you finance an extra $2,000 at 7.14% / 60 months: Monthly payment increases by about $40 Total extra interest ≈ $385 over 5 years If you pay the $2,000 at signing: Monthly payment stays lower You need $2,000 more cash on day one
Use the North Dakota calculator’s roll-tax and roll-fees checkboxes to see both sides with your actual price and down payment.
North Dakota Lending Notes (Not Calculator Line Items)
- Retail installment (NDCC ch. 51-13): a seller who makes the required disclosures is deemed a regulated lender under § 47-14-09 — finance charge as agreed / TILA path, not a hard add-on table in this brief.
- Delinquency: 10% of the delinquent installment or $10, whichever is less, after more than 10 days; only one such charge per installment — NDCC § 51-13-02.
- No FTC cooling-off on a dealership purchase.
- GAP / warranties: if financed, add to principal, not to the 5% excise base (excise is on vehicle purchase price).

How the North Dakota Auto Loan Calculator Works
Our VehicleTaxCalculator.com North Dakota auto loan calculator follows the same logic described in this guide:
- Purchase details — You enter price, down payment, trade-in, payoff, rebates, and any taxable or non-taxable doc fees per North Dakota law.
- Tax computation — The tool applies the official North Dakota rate or formula to the correct taxable base (which may differ for dealer vs private-party purchases).
- Fees — Title, registration, plate, and state-specific surcharges use official defaults where published; county or local add-ons stay user-entered.
- Roll-in flags — Choose whether to finance taxes and/or title and registration fees.
- Financing — APR defaults to 7.14% (G.19 60-month new-car bank average); term defaults to 60 months. Change both to match your lender.
- Results — You see tax breakdown, amount financed, estimated monthly payment, cash due, total of payments, and total interest.
Example: Using the calculator for a quick check
Scenario: You are buying a $32,000 vehicle with $4,000 down at a North Dakota dealer. You plan to roll tax and fees into the loan and your credit union quoted 6.9% for 72 months.
Enter: Price $32,000 | Down $4,000 | APR 6.9% | Term 72 Enable: Roll tax into loan | Roll fees into loan Compare: Monthly payment and cash due vs dealer worksheet
If the dealer’s payment is far higher, ask which fees were included in the tax base or amount financed—North Dakota rules may treat doc fees, trade-ins, or rebates differently than you assumed.
Common Questions
Should I roll taxes into my loan?
Rolling North Dakota’s vehicle tax or excise into financing does not change how much tax you owe. It spreads the cost across monthly payments and adds interest. Many buyers finance tax for cash-flow reasons; others pay at the tag office to save interest.
What APR should I use?
The Federal Reserve G.19 series publishes a 60-month new-car bank average of 7.14% (Q2 2026). That is an illustration, not your guaranteed rate. G.19 does not publish used-car APRs—enter your lender’s quote.
Are dealer doc fees official?
Most states do not publish average doc fees as government data. North Dakota may cap or tax doc fees differently; see the official fee table above. Default doc fees to $0 unless you know your dealer’s charge.
Is this a Truth in Lending disclosure?
No. Any online calculator—including ours—is an estimate for planning. Your signed retail installment contract and lender disclosures control the binding payment and APR.
Should I rely on Experian / Edmunds / Bankrate / LendingTree APRs or credit-tier tables?
No. Experian / Edmunds / Bankrate / LendingTree APRs or credit-tier tables is not an official government figure for calculator defaults. Use only statute-backed rates and fees, or enter your own numbers.
Should I rely on CarEdge (or any) average doc fee?
No. CarEdge (or any) average doc fee is not an official government figure for calculator defaults. Use only statute-backed rates and fees, or enter your own numbers.
Should I rely on State/local sales tax stacked on a titled highway vehicle?
No. State/local sales tax stacked on a titled highway vehicle is not an official government figure for calculator defaults. Use only statute-backed rates and fees, or enter your own numbers.
Should I rely on Georgia TAVT?
No. Georgia TAVT is not an official government figure for calculator defaults. Use only statute-backed rates and fees, or enter your own numbers.
Should I rely on Putting doc fees into the 5% base?
No. Putting doc fees into the 5% base is not an official government figure for calculator defaults. Use only statute-backed rates and fees, or enter your own numbers.
Should I rely on A non-reciprocal credit for tax paid in a state that does not credit ND?
No. A non-reciprocal credit for tax paid in a state that does not credit ND is not an official government figure for calculator defaults. Use only statute-backed rates and fees, or enter your own numbers.
What Belongs in a Calculator vs What You Must Enter
| Input | Official default? | Notes |
|---|---|---|
| State vehicle tax / excise rate | Yes — per statute | 5.0% |
| Title and registration fees | Yes — where fixed | State fee schedule |
| APR (new, illustrative) | Yes — 7.14% at 60 mo | Fed G.19 Q2 2026 only |
| Vehicle price, down, trade | No | You enter |
| Used-car APR | No | No government series |
| Doc fee average | No | Default $0 unless capped by law |
| Credit score tiers | No | Not published officially |
| County / local add-ons | Often user-entered | Verify local schedule |
Data Sources and Accuracy
This guide and the North Dakota auto loan calculator rely on:
- North Dakota statutes and administrative rules cited in the official fact brief
- State department of revenue and motor vehicle publications (fee schedules, tax bulletins, forms)
- Federal Reserve G.19 and H.15 releases for benchmark interest rates
Rates and fees can change when the legislature acts or when agencies update bulletins. Always confirm final amounts with your lender and North Dakota motor vehicle office before signing.
Conclusion
North Dakota car financing is built on three layers: vehicle tax or excise (how you buy determines the tax base), official title and registration fees (fixed dollar amounts where published), and loan math (amount financed, APR, and term—with government benchmarks only for new-car bank averages, not your personal rate).
The biggest mistakes shoppers make are using another state’s tax model, trusting credit-tier APR tables with no official source, or forgetting that rolling tax into the loan increases total interest. Work through your deal with the purchase channel, roll-in choices, and your lender’s actual quote—and compare the result to the state’s own publications when you are ready to title the vehicle.
