The New Hampshire Auto Loan Calculator estimates your real monthly car payment in New Hampshire, where there is no statewide vehicle sales tax. Many payment calculators ignore sales tax, which understates what you actually borrow.
How it works
The tool builds your financed amount in three steps, then amortizes it.
- Trade-in credit — your trade-in value is subtracted from the car price first.
- New Hampshire sales tax — New Hampshire charges 0.00% statewide vehicle sales tax, so no tax is added to the taxable amount.
- Down payment — your cash down is subtracted to give the financed balance.
The monthly payment uses the standard amortization formula:
M = P * r * (1 + r)^n / ((1 + r)^n - 1)
where P is the financed amount, r is the monthly rate (APR / 12), and n is the number of months (years * 12). When the APR is 0, the payment is simply P / n.
Example
Take a $32,000 car in New Hampshire with a $6,000 trade-in and $3,000 down, financed at 7.5% APR over 5 years. Because New Hampshire has no vehicle sales tax, the taxed price stays at the $26,000 taxable amount. After the $3,000 down payment you finance about $23,000. That works out to roughly $461/month, with about $4,652 in total interest over the 5-year term.
Notes
This is an estimate for planning only, not financial or tax advice. New Hampshire has no statewide vehicle sales tax, but local fees, title and registration costs still apply. Title, registration and dealer fees are not included. Verify the exact tax, fees and APR with your New Hampshire dealer, lender and the New Hampshire Department of Revenue or motor-vehicle agency before committing.
