Refinance Calculator

Refinance Calculator - Compare Your Loan Refinancing Options

Our refinance calculator helps you evaluate whether refinancing your existing loan is a good financial decision. By comparing your current loan terms with potential new loan options, you can see exactly how much you could save in monthly payments and total interest, and determine your break-even point.

How to Use the Refinance Calculator

Enter your current loan details and the proposed new loan terms to get an instant comparison. The calculator supports two methods for entering your current loan:

I know my remaining balance: Enter your remaining loan balance, current monthly payment, and interest rate
I know the original loan amount: Enter your original loan amount, original loan term, and time remaining

For the new loan, enter the proposed term, interest rate, points, closing costs, and any cash out amount to see a complete side-by-side comparison.

Understanding the Results

The calculator provides a comprehensive comparison including:

Monthly Payment Comparison: See your current monthly payment versus the new proposed payment
Monthly Savings: The difference between your current and new monthly payment
Interest Analysis: Compare total interest paid under both scenarios
Break-Even Analysis: How many months it will take for your monthly savings to cover the closing costs
Total Interest Saved: The net interest savings over the life of the new loan

When Should You Consider Refinancing?

Refinancing can be beneficial in several situations:

Lower Interest Rates: If market rates have dropped significantly below your current rate
Improved Credit Score: A higher credit score may qualify you for better rates
Need for Cash: Cash-out refinancing to access home equity for improvements or debt consolidation
Shorter Loan Term: Switching from a 30-year to a 15-year mortgage to pay off your loan faster
Lower Monthly Payments: Extending your loan term to reduce monthly obligations

Refinance Calculation Formula

The calculator uses the standard loan amortization formula to determine monthly payments:

M = P × [r(1+r)^n] / [(1+r)^n - 1]

Where:

M = Monthly payment
P = Principal loan amount
r = Monthly interest rate (annual rate ÷ 12)
n = Total number of payments (months)

Understanding Break-Even Point

The break-even point is one of the most important metrics in refinancing decisions. It tells you how many months it will take for your monthly savings to offset the total closing costs. If you plan to stay in your home beyond the break-even period, refinancing may be worthwhile. If you plan to move before then, the upfront costs may not be justified.

Frequently Asked Questions

What is loan refinancing?

Loan refinancing involves taking out a new loan, usually with more favorable terms, to pay off an existing loan. This is commonly done with mortgages, auto loans, and student loans to secure lower interest rates, reduce monthly payments, or change loan terms.

How much does it cost to refinance a mortgage?

Refinancing costs typically range from 2% to 6% of the loan amount. Common costs include application fees, appraisal fees, title search, origination fees (points), and document preparation fees. These costs are factored into the break-even analysis in our calculator.

What is a good break-even period for refinancing?

A break-even period of 2 to 3 years (24 to 36 months) is generally considered good for refinancing. If you can recover the closing costs within this timeframe and plan to stay in the home beyond that, refinancing is likely a sound financial decision.

Can I refinance with a cash-out option?

Yes, cash-out refinancing allows you to borrow more than your remaining balance and receive the difference in cash. This can be useful for home improvements, debt consolidation, or other major expenses. Most lenders require at least 20% equity in your property for a cash-out refinance.

What is the difference between rate-and-term and cash-out refinancing?

Rate-and-term refinancing changes only the interest rate and/or loan term without changing the loan balance. Cash-out refinancing increases the loan balance beyond what is owed, allowing you to access your home equity as cash. Rate-and-term refinancing is generally less expensive and easier to qualify for.
