What is the Loan Payment Calculator?

This payment calculator computes your fixed monthly loan payment using the standard amortization formula. You enter the loan amount (principal), annual interest rate, and term in years or months. It shows your monthly payment, total interest over the life of the loan, and a breakdown of principal vs interest. You can also compare different term lengths and see the first 12 months of the payment schedule.

The result is the same every month; only the split between principal and interest changes. Early in the loan, most of each payment goes to interest. As the balance drops, more of each payment goes to principal.

Payment Formula

The standard formula for a fixed monthly payment (amortizing loan):

M = P × [r(1+r)^n] ÷ [(1+r)^n − 1]

M = monthly payment, P = principal (loan amount), r = monthly interest rate (annual rate ÷ 12), n = total number of payments

Exempel:

For a $25,000 loan at 7.5% annual rate over 5 years (60 payments): r = 0.075/12 ≈ 0.00625, n = 60. The formula gives your fixed monthly payment.

Nyckelbegrepp

Rektor

The amount you borrow. Each payment pays down principal and interest; early on, most of the payment is interest.

Term length

Shorter terms mean higher monthly payments but less total interest; longer terms mean lower payments but more interest paid over time.

Amortering

The process of paying off the loan over time with equal monthly payments. The schedule shows how each payment is split between principal and interest each month.

Monthly payment

The fixed amount you pay each period. It stays the same; the split between principal and interest changes over time—early payments are mostly interest.

Total interest

The sum of all interest over the life of the loan. Shorter terms reduce this; longer terms increase it.

Ränta %

The percentage of your total payments that goes to interest (vs principal). A lower percentage means you pay less in interest relative to the amount borrowed.

Term comparison and schedule

Compare how different term lengths (12, 24, 36, 48, 60, 72 months) affect monthly payment and total interest. The schedule shows the first 12 months: payment, principal, interest, and remaining balance.
