Formula & Calculation Logic

Monthly Payment: M = P × [r(1+r)^n] / [(1+r)^n - 1]. Total Payback = M × n. Total Interest = Total Payback - P.

Frequently Asked Questions

How is monthly loan payment calculated?

Using the standard amortization formula: M = P[r(1+r)^n] / [(1+r)^n - 1], where P is principal, r is monthly interest rate, and n is total number of monthly payments.

Can this calculate car loan payments?

Yes! Loan Calculator works perfectly for auto loans, personal loans, and student loans.

Does paying extra principal each month save money?

Yes, paying additional principal reduces the outstanding balance faster, substantially decreasing the total interest accrued over the life of the loan.

What is the difference between a fixed-rate and variable-rate loan?

A fixed-rate loan maintains an identical interest rate and monthly payment for the entire term, whereas variable-rate loans fluctuate with benchmark market rates.
