Methodology & Formulas

Our calculations strictly follow standard amortization formulas used by financial institutions worldwide. We prioritize accuracy to legal standards.

Monthly Payment Formula

We calculate monthly payments using the standard amortization formula: $$M = P \frac{r(1+r)^n}{(1+r)^n - 1}$$ Where: $M$ is the total monthly payment, $P$ is the principal loan amount, $r$ is the monthly interest rate (annual rate divided by 12), and $n$ is the number of payments (loan term in months).

Break-Even Point Calculation

The break-even point represents the time it takes for your monthly savings to recover the closing costs of the new loan. $$Break\ Even\ Months = \frac{Total\ Closing\ Costs}{Monthly\ Savings}$$ We divide the total upfront cost of refinancing by the difference between your current and new monthly payments.

Total Interest Savings

We calculate the total interest payable for the remaining term of your current loan and compare it against the total interest payable on the new loan.

When Should You Refinance?

Refinancing is typically beneficial when you can secure a lower interest rate, shorten your loan term, or convert an adjustable-rate mortgage (ARM) to a fixed-rate mortgage. A common rule of thumb is that refinancing makes sense if you can lower your rate by at least 1% or if you plan to stay in the home long enough to reach the break-even point.

Understanding Closing Costs

Refinancing isn't free. Closing costs can range from 2% to 6% of your loan amount. These may include application fees, origination fees, appraisal fees, and title insurance. Our calculator subtracts these costs from your gross savings to show your true net benefit.

Frequently Asked Questions

Q:What is a good break-even point for refinancing?

A break-even point of 30 months (2.5 years) or less is generally considered excellent. A period between 30 and 48 months is often acceptable if you plan to stay in the home for significantly longer than that. If the break-even point exceeds 5-7 years, refinancing may be risky if your plans change.

Q:Does refinancing hurt my credit score?

Initially, yes. Applying for a refinance triggers a hard inquiry, which may drop your score by a few points. However, ensuring consistent on-time payments on your new loan will help improve your credit score over time.

Q:Can I refinance with bad credit?

It is more difficult but possible. You may not qualify for the lowest advertised rates. Lenders often require a credit score of at least 620 for conventional loans, though FHA loans may accept lower scores. Improving your score before applying can significantly increase your potential savings.

Q:What is a cash-out refinance?

A cash-out refinance allows you to borrow more than you owe on your home and take the difference in cash. This is often used for home improvements or debt consolidation. Keep in mind this increases your total loan amount and may result in a higher interest rate compared to a rate-and-term refinance.
