How do I calculate my monthly loan payment?

Enter your loan amount, interest rate, and term. The calculator uses the standard amortization formula to compute your fixed monthly payment.

Does paying extra reduce total interest?

Yes. Extra payments go directly to principal, reducing the balance faster. This shortens the loan term and significantly reduces total interest paid.

What is the difference between APR and interest rate?

APR includes the interest rate plus fees and closing costs, annualized. It gives a more complete picture of the true cost of borrowing.

How Loan Payments Are Calculated

Fixed-rate loan payments use the same amortization formula as mortgages. The formula calculates a constant monthly payment that covers both principal repayment and interest charges over the loan term. Early in the loan, most of each payment goes to interest; as you pay down the principal, more goes to paying off the balance.

Loan Payment Formula

Monthly Payment = P × [r(1+r)ⁿ] / [(1+r)ⁿ − 1]

Where: P = principal, r = monthly rate (APR/12), n = total payments (years × 12)

Example Calculations

Auto Loan: $25,000 at 5.9% for 5 years

Monthly: $482.82 | Total interest: $3,969 | Total: $28,969

Personal Loan: $10,000 at 8% for 3 years

Monthly: $313.36 | Total interest: $1,281 | Total: $11,281

Loan Types Compared

Auto loans: 3-7 years, 4-10% APR. Personal loans: 2-7 years, 6-36% APR. Student loans: 10-25 years, 4-8% APR. Business loans: 1-10 years, 6-30% APR. Rates depend on credit score, lender, and market conditions.
