Direct Answer

What auto calculator should I use?

The right calculator depends on which decision you're facing. For affordability questions — "how much car can I afford?" — start with the Car Affordability Calculator to set your budget before shopping. For active car-shopping — comparing dealer offers, rebates, lease vs buy — use the Car Loan Calculator as the foundation, then layer in Rebate vs Low APR or Lease vs Buy to evaluate specific manufacturer offers.

For ownership cost planning — projecting the total cost beyond the monthly payment — use the True Cost of Ownership calculator (which folds in fuel, insurance, maintenance, and depreciation). For refinancing an existing loan, the Auto Refinance Calculator tells you whether dropping your current rate would save enough to justify the application. Below, all 10 calculators are organized by the decision type they answer.

The four auto-financing decisions that matter most

Auto financing in 2026 sits at the intersection of higher interest rates, returning manufacturer incentives, and tighter affordability constraints. The average new vehicle is now financed for $42,332 with a $742 monthly payment (Experian Q3 2025), and the average loan term has stretched to nearly 70 months. Every major decision in this space falls into one of four domains:

1. Affordability — Can I responsibly buy this car?

Before any rate or rebate matters, the question is whether the vehicle fits your budget. The standard guidance: keep total monthly transportation costs (loan + insurance + fuel + maintenance) under 10-15% of gross income, with a 20% down payment and a loan term no longer than 4 years. The Car Affordability Calculator models this constraint with your actual numbers. Skipping this step is the most expensive mistake in the entire decision tree — buying too much car compounds with every other downstream choice.

2. Financing — Where does the money come from?

Once the price is set, financing splits three ways: bank/credit union, dealer captive lender, or cash. Bank and credit union pre-approvals give you a baseline rate to evaluate against any dealer offer. Captive promotional rates (0%, 0.9%, 1.9% APR offers from Toyota Financial Services, Ford Motor Credit, etc.) are real but conditional on credit tier and inventory targets. The Dealer vs Credit Union calculator and Rebate vs Low APR calculator answer this domain.

3. Lease vs Buy — Own the vehicle or rent it?

Leasing trades long-term cost for short-term flexibility. Buying typically saves $15,000-$25,000 over a 10-year horizon, but leasing offers lower monthly payments and predictable 3-year turnover. The Lease vs Buy Calculator models both scenarios with your specific vehicle and financing terms. Lease pricing is also subsidized by captive lenders through artificially inflated residual values — a subtlety that affects how the math plays out.

4. Ownership Cost — What does this car actually cost me?

The monthly payment is the visible cost; depreciation, insurance, fuel, and maintenance are the hidden costs. AAA estimates the total annual cost of owning a typical new car at approximately $12,182 in 2024. The True Cost of Ownership, Vehicle Depreciation, EV vs Gas Cost, and Car Insurance Estimator calculators all answer questions in this domain. For long-term planning, this is the most important domain — and the most underestimated.

2026 Live Data

Current 2026 auto loan rates

Where today's auto loan market sits, by loan term and credit tier. These numbers shape every downstream financing decision — they're the baseline against which any dealer promotional offer should be compared.

Rates by loan term (Federal Reserve G.19)

Loan TermAverage APR (Q1 2026)What it means
48-month new auto7.42%Higher than 60-mo because banks reserve their best rates for terms they prefer
60-month new auto6.96–6.97%Most common term; this is the default rate most buyers face
72-month new auto7.50%Longer term = higher rate + more total interest + more time underwater
Credit union average~0.4–0.6% below bankCU rates run about 50 basis points lower than commercial bank averages
Dealer promotional APR0% – 4.99%Captive lender subsidized rate — manufacturer pays the difference

Rates by credit tier (Experian Q4 2025)

Credit TierFICO RangeAvg New-Auto APR
Super prime781–8504.66%
Prime661–780~6.5%
Near prime601–660~9.5%
Subprime501–600~13.0%
Deep subprime300–50016.01%

2026 outlook: Bankrate's 2026 forecast bakes in three quarter-point Federal Reserve rate cuts, projecting auto APRs to fall roughly 0.33 percentage points over the year. Manufacturers are responding to affordability pressure by increasing incentives — CDK Affordability Tracker measured the average incentive at $1,611 in February 2026, up 76% from $698 a year earlier.

All 10 auto calculators

Each calculator targets a specific decision. Match the calculator to your question — most car-buying journeys touch 3-4 of these.

Car Loan Calculator
Project monthly payment, total interest, and amortization for any vehicle price, down payment, term, and APR.
Use when: you have a target vehicle and need to model the monthly payment.
Rebate vs Low APR
Compare cash rebate plus your bank's rate against the dealer's promotional 0-2.9% APR offer. Identifies the winner in dollars.
Use when: the dealer offers you a choice between cash off or low financing.
Lease vs Buy
Compare total 36-month lease cost against 60-month purchase plus 24-month ownership tail. Includes residual and mileage assumptions.
Use when: deciding between leasing or buying the same vehicle.
Dealer vs Credit Union
Side-by-side comparison of dealer-arranged financing against a pre-approved credit union loan, including markup and reserve fees.
Use when: you have or can get a pre-approved CU rate to compare with the dealer's offer.
Auto Refinance
Model interest savings from refinancing your existing auto loan at a lower rate, accounting for remaining term and any fees.
Use when: your current rate is >1.5% above market and you have 24+ months remaining.
Auto Early Payoff
Calculate interest saved by paying extra principal each month or making one lump-sum payment toward your auto loan.
Use when: you have extra cash and want to know if early payoff beats other uses.
True Cost of Ownership
Five-year projection covering depreciation, fuel, insurance, maintenance, and financing — the full picture beyond the monthly payment.
Use when: comparing two vehicles that look similar on price but have very different ownership costs.
Vehicle Depreciation
Estimate your vehicle's value at any future year based on age and class. New cars lose ~20% in year one, 50-60% by year five.
Use when: evaluating trade-in timing or comparing new vs 2-3 year-old vehicles.
EV vs Gas Cost
Five-year total cost comparison between an electric vehicle and a gasoline equivalent — fuel, charging, maintenance, depreciation.
Use when: considering an EV and want to model the actual cost difference vs a gas alternative.
Car Insurance Estimator
Estimate annual premium based on state, driver age, vehicle class, and coverage level. National average: $2,313/year for full coverage.
Use when: budgeting total ownership cost or comparing insurance impact of two vehicles.

Which calculator fits your situation?

Most car-buying journeys touch 3-4 calculators in sequence. Use the situation that matches yours as the starting point.

"I want to buy a car but don't know what I can afford."
Start with Car Affordability to set your monthly ceiling, then use True Cost of Ownership to factor in insurance, fuel, and maintenance before fixing your target vehicle price.
"I have a vehicle picked out — what will my monthly payment be?"
Use Car Loan Calculator with your target price, down payment, term, and a realistic APR (start with the 2026 rate card above for your credit tier).
"The dealer is offering me a rebate OR low APR — which is better?"
Use Rebate vs Low APR to compare exact total cost. At today's average 6.97% APR, a 0% promo creates a roughly 7-point gap that usually dominates rebate math.
"I'm not sure if I should lease or buy."
Use Lease vs Buy to compare total cost over the same time horizon. Generally: lease if you turn over cars every 2-3 years and drive under 12,000 miles annually; buy if you keep cars 5+ years.
"I want to know if a credit union beats the dealer's financing."
Get a CU pre-approval, then use Dealer vs Credit Union. The CU rate is usually 0.4-0.6% lower than commercial bank averages and 1-3% lower than dealer markup on standard financing.
"I'm already in an auto loan — should I refinance?"
Use Auto Refinance Calculator. Refi makes sense if your rate dropped 1.5+ points, you have 24+ months remaining, and you have positive equity (LTV under 110%). If your current rate is a 0-2% promo, don't refinance.
"I'm comparing two vehicles that cost about the same."
Run both through True Cost of Ownership — vehicles with similar sticker prices can differ by $10,000-$20,000 over five years once depreciation, insurance, and fuel are factored in.
"I'm thinking about an EV instead of gas."
Use EV vs Gas Cost for a five-year comparison. EVs typically have higher upfront costs but lower fuel and maintenance costs. Note: federal EV tax credit ended September 2025.

Frequently Asked Questions

What's the average auto loan rate in 2026?
Bankrate's weekly survey reports 6.97% for 60-month new auto loans as of May 2026. Statista reports 6.96% as of March 2026. Super prime borrowers (FICO 781+) average 4.66%; deep subprime averages 16.01%. Credit union rates typically run 0.4-0.6 percentage points below commercial bank averages.
How much car can I afford?
The standard guidance is 10-15% of gross monthly income for the total monthly auto cost (loan payment plus insurance, fuel, and maintenance). On a $75,000 salary that's $625-$940/month total. The 20/4/10 rule adds: 20% down payment, 4-year loan term maximum, and total transportation under 10% of gross income.
Is leasing or buying cheaper?
Buying is cheaper long-term if you keep the car 5+ years. Leasing makes sense if you want a new car every 2-3 years, drive under 12,000 miles annually, and prefer predictable lower monthly payments. Over a 10-year horizon, buying typically saves $15,000-$25,000 versus consecutive 3-year leases on the same vehicle class.
Should I take the cash rebate or 0% financing?
When the dealer's promotional APR is more than 3 percentage points below your bank or credit union rate, low-interest financing usually saves more money. When the gap is smaller or the rebate is large relative to the loan amount, take the cash. At today's 6.97% average auto APR, a 0% promo creates a roughly 7-point gap that dominates most rebate math.
What credit score do I need for the best auto loan rates?
Super prime credit (FICO 781+) qualifies for the lowest rates, averaging 4.66% in Q4 2025 per Experian. Prime credit (661-780) averages around 6.5%. Captive promotional rates (0% APR offers) almost always require super prime or strong prime credit; subprime borrowers typically don't qualify for these promotions.
Is a credit union better than a dealer for auto financing?
For standard market-rate loans, yes — credit union rates run 0.4-0.6 percentage points below commercial bank averages, and dealers typically mark up captive lender buy rates by 1-3 points for non-promotional financing. Get pre-approved at a credit union before shopping; use that rate as a baseline to evaluate any dealer offer.
How long should I finance a car?
60 months or shorter is recommended. Federal Reserve G.19 data shows 60-month rates average 6.97% while 72-month rates average 7.50% — longer terms cost more on every dimension: more total interest, higher rate, and more months you spend underwater on the loan. Never go beyond 60 months unless absolutely necessary.
Can I refinance my auto loan?
Yes, but it only makes sense if (1) your rate drops at least 1.5 percentage points, (2) at least 24 months remain on the loan, and (3) you have positive equity (LTV under 110%). If you took a subvented promotional rate (0-1.9% APR), don't refinance — you'd replace a below-market rate with a market rate.
What is the true cost of owning a car?
The American Automobile Association estimates the average total annual cost of owning a new car at approximately $12,182 in 2024. That includes depreciation, financing, fuel, insurance, maintenance, and registration fees. On a 10-year horizon, a typical mid-priced new car costs $90,000-$120,000 in total ownership expenses.
How much does insurance add to my monthly car cost?
The national average for full-coverage auto insurance is approximately $2,313 per year (about $193/month) per the Insurance Information Institute 2025 data. State, age, driving record, and vehicle type cause wide variation: Maine averages around $1,200/year, while Louisiana exceeds $3,500/year.
Are electric vehicles cheaper to own than gas vehicles?
Generally yes, on a 5-year total-cost basis. Electric vehicles have higher upfront prices but significantly lower fuel costs (electricity averages $0.04-$0.06 per mile vs $0.15-$0.20 for gasoline) and lower maintenance costs (no oil changes, fewer moving parts). The federal EV tax credit ended in September 2025, so 2026 comparisons exclude that incentive.
How fast do cars depreciate?
New vehicles lose approximately 20% of their value in the first year and 50-60% by year five. Luxury vehicles and EVs depreciate fastest; trucks and SUVs depreciate slowest. Buying a 2-3 year old vehicle avoids the steepest depreciation drop while still getting a vehicle with most of its useful life remaining.
What is dealer cash and can I get it?
Dealer cash is an incentive paid by the manufacturer to the dealer (not to you) to move slow inventory or hit volume targets. Dealer cash typically ranges from $500 to $4,000 but can exceed $50,000 on slow-selling luxury models. You can't see it directly; the practical workaround is getting firm out-the-door price quotes from 3-4 dealers — those with extra dealer cash will quote lower prices to win the sale.
When is the best time of year to buy a new car?
Three windows produce the largest incentives: end of month (last 3-5 days when salespeople need to hit volume targets), end of quarter (last 2 weeks of March, June, September, December when manufacturer incentive budgets deploy unused funds), and model-year changeover (typically July-October when outgoing inventory carries the largest discounts of the cycle).
