How the loan calculator with extra payments work?

The loan calculator with extra payments is used to estimate your monthly payments and see how making additional payments to reduce loan balance can save you money over the course of the loan. Standard Loan Information - The standard loan calculator requires only 3 variables, loan amount, interest rate, and term to calculate your monthly payments. Extra Payments - You can add extra payments either on a monthly, quarterly, biweekly, yearly basis or as one-time lump sums. This extra payment feature shows you how paying a little extra can reduce both your loan balance and the overall interest paid, and how much quicker you can pay off the loan.
