Understanding the Mortgage Formula
The calculator uses a standard loan amortization formula:
Monthly Payment Formula:
M = P × [r(1+r)^n] ÷ [(1+r)^n – 1]
Where:
- P = Loan amount
- r = Monthly interest rate
- n = Total number of payments (15 × 12 = 180)
Additional Calculations:
- Total Paid = Monthly Payment × Number of Payments + Closing Costs
- Total Interest = Total Paid – Loan Amount – Closing Costs
- Monthly Savings = Current Payment – New Payment
- Break-Even = Closing Costs ÷ Monthly Savings
