About This Tool

Our Mortgage Refinance Calculator helps homeowners determine whether refinancing their home loan is financially beneficial. By comparing your current mortgage terms with potential new rates, you can quickly calculate your monthly savings, total interest savings over the life of the loan, and most importantly, your break-even point—the time it takes for the savings to offset the closing costs. Whether you're looking to lower your monthly payments, shorten your loan term, or tap into home equity, this calculator provides the insights you need to make an informed decision. Many homeowners save thousands of dollars by refinancing when rates drop, but timing and costs matter significantly.

How to Use

  1. Enter your current loan balance, interest rate, and years remaining on your mortgage.
  2. Input the new interest rate you're considering and your desired loan term.
  3. Add estimated closing costs, which typically range from 2% to 5% of the loan amount.
  4. Click "Tasarrufu Hesapla" to see your monthly savings, break-even point, and total interest savings.

Frequently Asked Questions

What is a mortgage break-even point?

The break-even point is the time it takes for your monthly savings from refinancing to equal the closing costs you paid. For example, if refinancing saves you $200 per month and costs $4,000 in closing costs, your break-even point is 20 months. If you plan to stay in your home longer than this period, refinancing makes financial sense.

How much can I save by refinancing my mortgage?

Savings depend on the loan balance, current and proposed rates, remaining and new terms, closing costs, and any applicable tax or fund assumptions. There is no universal rate-drop threshold: enter the actual offer you are comparing and use the calculated payment and break-even result as a planning scenario, then verify the lender quote before deciding.

When is the best time to refinance?

There is no universal best time to refinance. Compare the specific offer against your current balance, rate, remaining term, new term, closing costs, and any applicable KKDF/BSMV assumptions. A lower payment alone does not establish that refinancing is beneficial; review break-even time and total modeled cost, then verify the actual lender terms.

What Mortgage Refinance Calculator Does and Why It Matters

Mortgage Refinance Calculator compares your current mortgage against a proposed new rate and term, estimating the monthly payment difference, total interest saved (or added), and how long it takes for the savings to cover any refinancing closing costs — the "breakeven" point.

A lower interest rate doesn't automatically mean refinancing is worth it: if you're planning to move or pay off the loan before reaching the breakeven point, the closing costs can outweigh the savings. This calculation makes that tradeoff visible instead of leaving it as a rough gut feeling.

How to Use Mortgage Refinance Calculator

  1. Enter your current loan balance, interest rate, and remaining term.
  2. Enter the proposed new rate, term, and any closing costs for the refinance.
  3. Review the estimated new monthly payment, total interest difference, and breakeven timeline.

What to Know

  • Closing costs vary by lender and loan size — use your actual quoted closing costs for an accurate breakeven estimate, not a generic assumption
  • This estimate doesn't include costs tied to the original loan being paid off (like any prepayment penalty) unless you enter them explicitly
  • This is a planning estimate, not a loan offer — actual refinance terms depend on your lender's underwriting and current market rates

Frequently Asked Questions

What is the "breakeven point" and why does it matter?

It's how long it takes for your monthly savings from the lower rate to add up to more than the closing costs you paid to refinance. If you plan to sell or pay off the loan before that point, refinancing likely isn't worth the upfront cost.

Does a lower rate always mean I should refinance?

Not necessarily — closing costs, how long you plan to stay in the home or keep the loan, and any prepayment penalty on your current loan all factor in. A lower rate with a long breakeven period may not be worth it if you won't hold the loan that long.

Will my actual new rate match what I enter here?

Only if that's the rate you've actually been quoted — this tool calculates the outcome of the numbers you provide, it doesn't determine what rate a lender will offer you, which depends on your credit, income, and current market conditions.
