Refinance Mortgage Payment Formula
The calculator uses the standard fixed-rate mortgage payment formula.
Monthly Mortgage Payment Formula
M = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)
Where:
- M = Monthly principal and interest payment
- P = Loan amount
- r = Monthly interest rate
- n = Total number of monthly payments
Monthly Interest Rate
Monthly Interest Rate = Annual Interest Rate ÷ 12 ÷ 100
Example:
Annual Rate = 6%
Monthly Rate =
6 ÷ 12 ÷ 100
= 0.005
Total Interest Formula
Total Interest = (Monthly Payment × Number of Payments) − Loan Amount
Total Monthly Payment Formula
Total Monthly Payment = Principal & Interest + Property Tax + Insurance
Total Cost Formula
Total Cost includes:
- Principal repayment
- Interest
- Property taxes
- Insurance
- Closing costs
This provides a complete estimate of the cost of refinancing.

Loan Amount: $250,000
Interest Rate: 5.5%
