Your Payment Summary
Where P = principal, r = monthly interest rate (annual rate ÷ 12), n = number of monthly payments.
Total repayment = M × n, Total interest = Total repayment - P.
Understanding Your Personal Loan Payments
A personal loan monthly payment consists of principal and interest. Early payments go mostly toward interest; over time, more goes toward principal. Use this calculator to compare different loan amounts, rates, and terms before you borrow.
Pro tip: A lower interest rate or shorter term can significantly reduce total interest, but may increase monthly payments. Find the balance that fits your budget.
Frequently Asked Questions About Personal Loan Payments
How is the monthly payment calculated for a personal loan?
We use the standard amortization formula: M = P × r × (1+r)^n / ((1+r)^n - 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. This formula assumes fixed interest and equal payments throughout the loan term.
What is the difference between APR and interest rate?
APR (Annual Percentage Rate) includes fees and other costs, while the interest rate only reflects the cost of borrowing principal. This calculator uses the nominal interest rate; your actual APR may be higher if fees apply. Always check loan terms for APR when comparing offers.
Can I use this calculator for auto loans or student loans?
Yes, this calculator works for any fixed-rate installment loan. It's suitable for auto loans, student loans, debt consolidation, and other personal financing. Simply enter the loan amount, rate, and term to see the monthly payment.
Does this calculator account for extra payments or early payoff?
This tool calculates standard monthly payments assuming no extra payments. For early payoff scenarios, please use our dedicated mortgage payoff calculator with extra payments.
