Loan Calculator
Estimate monthly payments and total interest for any loan.
What Is the Loan Calculator?
A loan calculator helps you understand the true cost of borrowing. By entering the loan amount, interest rate, and term, you can see your monthly payment, total interest paid, and the full payoff schedule.
The Formula
Monthly Payment = P x [r(1+r)^n] / [(1+r)^n - 1] where P is principal, r is monthly rate, n is number of payments.
Example
A $25,000 auto loan at 6% APR over 60 months yields a $483 monthly payment with $3,999 in total interest over the life of the loan. A $15,000 personal loan at 9% for 36 months costs $477 per month with $2,171 in total interest.
Common Uses
Auto loans, personal loans, student loans, debt consolidation planning.
