Loan Calculator
Quick answer
Enter principal, APR, and months in term. Payment solves PMT; then scan amortization for interest-heavy early years.

What moves the payment
Fixed-rate amortizing loans use principal, APR, and term. APR calculators include fees in the effective rate. Credit cards revolve—interest compounds on average daily balance. Debt payoff order changes total interest when you redirect surplus dollars. When you need the effective rate with fees, use an APR calculator alongside the payment.

This intent is the broad “installment loan” frame: amount, rate, term, and optional extra principal. It is the same family of math as mortgage P&I, but without the purchase-price and escrow stack—useful when you’re comparing car, personal, or consolidation offers. When you only care about the monthly line item, cross-check with a monthly loan payment calculator.
How to use this calculator
- Match the loan type: Auto and personal loans are usually simple amortization; verify if your rate is add-on or simple interest.
- APR vs note rate: If fees are financed, effective APR is higher. For apples-to-apples, compare APR disclosures.
- Extra payments: Add recurring principal to see payoff acceleration—servicer must apply to principal. If you are stacking multiple debts, see a debt payoff calculator before you optimize one loan in isolation.
Real-world examples
- Example: $18,000 @ 8.9% for 60 months: Payment often lands near $370–$375/mo before fees; total interest in the low $4k range (illustrative).
- Sensitivity check: Nudge the rate by about +0.5% and the principal by about −5%. If the payment, break-even, or target amount moves enough to change your decision, you are still on a steep part of the curve where small inputs matter.
What this means
Early years on long installment loans are interest-heavy—extra principal in the first third of the term saves more lifetime interest than the same dollars after half the term.
FAQ
How do I calculate a loan payment?
Enter principal, APR, and term in months; the tool solves the fixed monthly payment (amortizing loan). For a home purchase with escrow, use a [mortgage calculator](/mortgage-calculator) so taxes and insurance are not missing.
What is included in “loan payment” vs mortgage payment?
Here, payment is principal and interest on the borrowed amount. A mortgage payment often adds property tax, insurance, and HOA — this calculator does not assume those unless you model them elsewhere.
Does paying extra principal reduce total interest?
Yes on standard amortizing loans when extra payments apply to principal. Confirm your loan has no prepayment penalties and that your servicer applies overpayments correctly.
Is APR the same as the interest rate?
Not always. APR reflects the effective annual cost including many fees; the note rate is the contract rate on the balance. Compare APR across offers when fees differ.
Is this a loan commitment?
No — outputs are educational. Your lender’s disclosures, APR, and fees govern the actual loan.
