Advanced Mortgage Payoff Calculator
Calculate mortgage payments, total interest, payoff time, and savings with extra payments and one-time contributions. Supports fixed and adjustable rate loans for accurate long-term planning.
Formulas Used
- Monthly Payment (EMI):
- M = P × [r(1+r)^n] / [(1+r)^n − 1]
- Monthly Interest:
- Interest = Remaining Balance × Monthly Rate
- Principal Payment:
- Principal = EMI − Interest
- Total Interest:
- Total Interest = Σ Monthly Interest
- Total Cost:
- Total Cost = Total Payments Made
- Interest Savings:
- Savings = Standard Interest − New Interest
