How It Works
1
Enter your loan amount, interest rate, term, start date, and any additional payments. Calculations are performed locally in your browser.
2
Our formula: M = P × r(1+r)^n / ((1+r)^n - 1), where P is principal, r is rate, n is payments.
3
Compare saved mortgage scenarios, review the amortization schedule, and visualize the remaining balance and monthly payments in the graph.
