What is a Payment Calculator?
A Payment Calculator quickly determines your monthly loan payment based on the loan amount, interest rate, and term. Use it to estimate payments for personal loans, car loans, mortgages, or any other fixed-term loan.
How to calculate payment manually (the formula)
The standard formula is: M = P [ r(1+r)n ] / [ (1+r)n – 1 ] where M is the monthly payment, P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments (term in years × 12).
Example calculation
For a $25,000 loan at 7% interest over 5 years: the monthly rate is 0.5833% (7% ÷ 12). Over 60 payments, the monthly payment is about $495. The total interest paid is roughly $4,705, making the total cost $29,705.
Common mistakes
- Only looking at the monthly payment — A lower monthly payment from a longer term means you pay much more in total interest. Always consider the full cost.
- Misunderstanding APR — APR includes both the interest rate and lender fees. Comparing APR gives a more accurate picture than comparing just the interest rate.
- Not accounting for variable rates — Some loans have rates that can change over time, which will increase or decrease your payment.
- Forgetting about insurance or fees — Some loans require insurance or have origination fees that affect the total amount you need to finance.
- Not checking for prepayment penalties — Paying off a loan early might trigger a penalty, reducing the benefit of early repayment.
Frequently asked questions
How does a payment calculator work?
A payment calculator uses the loan amount, interest rate, and term to determine your monthly payment. It applies the standard amortisation formula to divide the total loan plus interest into equal monthly instalments.
What is the difference between a payment calculator and a loan calculator?
A payment calculator focuses on the monthly payment amount. A loan calculator often provides additional details like total interest, amortisation schedules, and comparison features.
Can I change the term to see how it affects payments?
Yes. Adjust the term length and recalculate to see how a shorter term increases the monthly payment but reduces total interest, or a longer term lowers payments but costs more over time.
How does the interest rate affect my payment?
A higher interest rate increases both your monthly payment and the total interest paid. Even a 1% difference can have a significant impact over the life of the loan.
Is this calculator free to use?
Yes, completely free with no sign-up or download required. You can use it as many times as you like.
