How is a loan payment calculated?

Loan payments use the same PMT formula as mortgages: M = P × [r(1+r)^n] / [(1+r)^n − 1]. P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments.

What is APR vs interest rate?

The interest rate is the base cost of borrowing. APR (Annual Percentage Rate) includes the interest rate plus other fees (origination fees, closing costs). APR gives a more accurate picture of the true cost of a loan.

What is a good interest rate for a personal loan?

Personal loan rates typically range from 6% to 36% depending on your credit score. Borrowers with excellent credit (740+) may qualify for rates below 10%. Average rates as of 2026 are around 11–12%.

Should I choose a shorter or longer loan term?

Shorter terms mean higher monthly payments but less total interest paid. Longer terms mean lower monthly payments but significantly more interest over the life of the loan. Choose based on what fits your monthly budget while minimizing total cost.

Can I pay off a loan early?

Most personal loans allow early payoff, and it saves significant interest. However, some loans have prepayment penalties — always check your loan agreement. Even paying a small extra amount monthly can cut months off your loan.
