This calculator uses the standard amortizing-loan formula, which produces an equal monthly payment for the entire loan term:
Where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the total number of monthly payments. For a 0% interest rate, this simplifies to Payment = Principal ÷ Number of Payments.
This calculator uses the standard amortizing-loan formula, which spreads principal and interest across equal monthly payments over the loan term. Each payment is split between interest (based on the remaining balance) and principal, with the interest portion shrinking and the principal portion growing over time.
With 0% interest, the payment is simply the loan amount divided evenly by the number of payments, since there's no interest to amortize.
Any extra amount you add goes entirely toward principal (never interest), which reduces the balance faster than scheduled. That means less interest accrues on future payments, so the loan is paid off sooner and for less total interest overall.
Total interest is the extra cost of borrowing on top of what you borrowed. Total amount paid is the loan amount plus that interest -- everything you'll actually pay back over the life of the loan.
No. This is a mathematical estimate based on the amount, rate, and term you enter. Actual loans often include fees, insurance, taxes, or rate types (like variable rates) this calculator doesn't model -- always confirm exact figures with your lender.
