What Is Mortgage Refinancing?
Mortgage refinancing involves replacing your current mortgage with a new one, usually with a lower interest rate or more favorable terms. Homeowners typically refinance to:
- Reduce monthly payments
- Shorten or extend the loan term
- Access home equity
- Save on total interest payments
A well-calculated refinance can significantly reduce your financial burden and help you achieve long-term financial goals.
How the Mortgage Refinance Calculator Works
The calculator uses standard mortgage formulas to estimate:
- New Monthly Payment – Your new expected monthly payment based on the new interest rate and remaining term.
- Estimated Interest Savings – The total amount of interest you may save by refinancing at a lower rate.
The calculation is based on the following formula for monthly mortgage payments:M=1−(1+r)−nP×r
Where:
- M = Monthly payment
- P = Loan principal (current balance)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of remaining payments (years × 12)
By comparing your current payment with the new payment, the calculator estimates your potential interest savings over the remaining term of your loan.
