How to calculate a loan payment
01
Enter the loan balance
This is the principal — the amount you're borrowing. For refinancing, use your current outstanding balance.
02
Set rate & term
Enter your annual interest rate (APR) and the loan term. Shorter terms mean higher payments but much less interest.
03
View full breakdown
See monthly payment, total paid, and the split between principal repayment and interest cost.
Frequently asked questions
How does the loan term affect total cost? ▼
Longer terms lower monthly payments but dramatically increase total interest. A $20,000 loan at 7% for 5 years costs ~$3,800 in interest. The same loan over 10 years costs ~$7,700 — more than double the interest.
Can I use this for any type of loan? ▼
Yes — this formula works for personal loans, auto loans, student loans, or any fixed-rate installment loan. For mortgage-specific calculations (including taxes and insurance), use our dedicated mortgage calculator.
What's a good loan-to-income rule? ▼
Financial experts suggest keeping total monthly debt payments (including this loan) below 36% of gross monthly income. For a single loan, aim for payments under 15% of take-home pay to maintain financial flexibility.
