Understanding the break-even point

Refinancing costs money upfront (closing costs). The break-even point is the number of months it takes for your monthly savings to cover those costs. For example, with $50,000 in closing costs and $2,000 monthly savings, you break even after 25 months — so refinancing makes sense if you plan to stay longer than that.

Refinance Calculator FAQ

Is a rate cut of 1% worth refinancing?
A 1% rate cut on a large balance can save thousands in interest and reduce your payment meaningfully — but only if the break-even point is comfortably inside how long you plan to stay.
Should I refinance to a shorter term?
A shorter term usually raises the monthly payment but saves a large amount of interest and builds equity faster. Use this calculator to compare totals before deciding.
Refinance: Replace loan with better terms
Rule: Save > 0.75% generally
Costs: 2–5% of loan value
Breakeven: Months to recover costs

Refinance Calculator — is it worth it?

Refinancing replaces your current loan with a new one at a lower rate or longer term. This calculator compares your current payment with the new proposed payment, computes the closing costs, and finds your breakeven — the months until savings offset costs.

When refinancing makes sense

Rate drop of 0.75–1% or more usually justifies refinancing if you plan to stay past the breakeven point.

Cash-out refinancing can convert home equity into cash — but never for consumption; use it for debt consolidation or renovation that adds value.

Shorten the term (e.g. 30→15 years) to build equity faster, even at a similar rate.

The breakeven calculation

Breakeven months = total closing costs ÷ monthly savings. If costs are $2,00,000 and you save $8,000/month, breakeven is 25 months.

If you plan to move or refinance again before breakeven, the refi loses money.

Online 'no-cost' refinances embed costs in a higher rate — compare total cost over your planned stay.

How to use this calculator

  1. Enter your current loan balance, rate and remaining term.
  2. Enter the proposed new rate and term.
  3. Add expected closing costs (2–5% of the loan).
  4. Read the new monthly payment, monthly savings, total interest saved and breakeven period.

Pro tips

  • Lock your rate only after comparing 3+ lenders.
  • Refinance to a shorter term when income allows — combine it with the lower rate for maximum savings.
  • Check if you can 'recast' instead: a lump-sum principal reduction keeps your rate but lowers the EMI at low or no cost.

Frequently asked questions

Is refinancing worth it?
Yes if the new rate is 0.75–1% lower AND you stay beyond the breakeven period (typically 1–3 years). Calculate your exact breakeven with this tool before committing.
What are typical refinance closing costs?
Expect 2–5% of the loan amount — appraisal, title, origination and processing fees. Lender-credit options can reduce these at the cost of a higher rate.
