Loan Calculator — FAQ
How is the monthly payment calculated?
Monthly payment = P × r(1+r)^n / ((1+r)^n – 1), where P = principal, r = monthly interest rate, n = number of months. This ensures equal payments throughout the loan term.
What is a good interest rate for a loan?
In 2026, personal loan rates typically range from 6% to 36% APR depending on credit score. Mortgage rates are currently lower (around 6–7%). Auto loans fall in between. Your credit score is the biggest factor — scores above 750 usually qualify for the best rates.
Does paying extra reduce interest?
Yes, significantly. Any extra payment goes directly toward the principal, reducing the balance on which future interest is calculated. Even one extra payment per year can save thousands in interest and cut months off your loan term.
