How to Calculate Mortgage Refinance Savings
Refinancing your mortgage can be a powerful financial move to lower your monthly expenses or reduce the total interest paid over the life of your loan. This calculator helps you determine if the upfront costs of refinancing outweigh the long-term benefits.
To use this calculator, you will need your current mortgage balance, your existing interest rate, and the rate offered by your new lender. You should also estimate the closing costs, which typically range from 2% to 5% of the loan amount.
Key Factors to Consider
- The Interest Rate Differential: Most experts suggest that a drop of at least 0.75% to 1% in interest rates makes refinancing worthwhile.
- Closing Costs: These are the fees paid to the lender and third parties to process the new loan. If you plan to move in 2 years, but it takes 3 years to break even on costs, refinancing might not be wise.
- Loan Term: If you refinance a 30-year loan into another 30-year loan after already paying for 5 years, you are extending your debt. While your monthly payment drops, your total interest paid could actually increase unless the rate drop is significant.
Example Calculation
Imagine you have a $300,000 balance at 6.5% interest with a current payment of $1,896. You are offered a new rate of 4.5% for 30 years with $5,000 in closing costs.
- New Payment: $1,520.06
- Monthly Savings: $375.94
- Break-Even: $5,000 / $375.94 = 13.3 months
In this scenario, if you stay in the home for more than 14 months, the refinance is financially beneficial.
When is the Best Time to Refinance?
The best time to refinance is when market rates are significantly lower than your current rate, or when your credit score has improved enough to qualify you for a much better tier. Additionally, homeowners with high-interest FHA loans often refinance into Conventional loans to remove private mortgage insurance (PMI) once they reach 20% equity.
