Consumer Loan Calculator

See what a consumer loan will cost you per month and in total over the term. Consumer loans typically carry a higher rate than mortgages, so the total cost can be significant.

Monthly payment

Amortizing loan, 5 years

Scenario: What happens at +1 percentage point interest?

At % interest, the monthly payment would be more per month than today.

How to use the consumer loan calculator

  1. Enter how much you plan to borrow.
  2. Enter the nominal annual interest rate — check your loan offer; consumer loans often carry 8–25% interest depending on your credit rating.
  3. Enter the desired repayment period. The calculator shows the monthly payment and total cost.

How the consumer loan is calculated

The calculator uses the same amortization formula as for other loans:

Monthly payment = L × r ÷ (1 − (1 + r)−n)
where L is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the number of months.

The difference from a mortgage is that consumer loan interest is far higher, since the loan isn't secured by any collateral. That makes the total cost — especially the interest portion — a much larger share of what you pay back.

Note: The calculation doesn't include origination or installment fees, which many consumer loans have. The effective interest rate (which includes these) will therefore be higher than the nominal rate you enter here. Always compare effective interest rates between offers.

Frequently asked questions

Why is the interest rate on consumer loans so much higher than on mortgages?

Consumer loans are unsecured, meaning there's no collateral like a home or other asset backing them. That makes the risk higher for the lender, which is reflected in a higher interest rate.

Should I refinance several consumer loans into one?

If you have several expensive small loans, it can often pay off to consolidate them into one refinancing loan with a lower rate. Try the refinancing calculator to see an estimate of the savings.

Is it cheaper to pay off the loan faster?

Yes. A shorter term gives a higher monthly payment, but significantly lower total interest costs since you pay interest for fewer months.
