How it works

This calculator uses the amortized-payment formula (constant monthly installments) — the standard for personal loans, mortgages and car loans.

Formula:

PMT = PV × i / (1 − (1 + i)⁻ⁿ)

PV = loan amount, i = monthly rate, n = number of installments.

Practical examples

$10,000 · 1.5%/mo · 24 months

Installment $499.24 · Total $11,981.68 · Interest $1,981.68.

$50,000 · 2%/mo · 36 months

Installment $1,961.16 · Total $70,601.82 · Interest $20,601.82.

Frequently asked questions

Is this APR or monthly rate?

Enter the monthly rate. For APR, divide by 12 as an approximation (or use (1+APR)^(1/12)−1 for exact compounding).

Does this include fees?

No. Origination fees, insurance and taxes are extra. Check the contract for the total effective cost.
