Rate-and-term, cash-out, and streamline refinance math
Refinance calculator for break-even month, closing costs, and lifetime savings.
A lower rate quote means nothing until closing costs are repaid. Enter your current balance and payment, then model the proposed loan with honest 2%–5% closing costs, taxes, insurance, and HOA — this page shows whether the refinance pays you back before you move, and whether rate-and-term, cash-out, or a streamline program fits your equity position in 2026.

Costs divided by monthly saving tells you the month the refinance starts winning.

Compare 15-year and 30-year loans
Use the comparison view to evaluate how shorter and longer mortgage terms change monthly payment and total interest. A shorter term usually costs more each month, but can reduce total borrowing cost over time.
Planning Notes
What affects your mortgage payment most
Loan amount
A larger loan amount usually increases monthly payment directly. Increasing the down payment lowers the amount financed and can reduce both monthly payment and total interest over the life of the loan.
Interest rate
Even small rate changes can materially affect long-term cost. Comparing scenarios across multiple rates is often one of the fastest ways to understand the sensitivity of a mortgage decision.
Loan term and recurring housing costs
Term length changes the tradeoff between monthly affordability and total interest. Taxes, insurance, and HOA can also meaningfully change the practical monthly payment even when the core loan stays the same.
FAQ
Mortgage calculator FAQ
How is monthly mortgage payment calculated?
Monthly mortgage payment is usually based on loan amount, interest rate, and loan term through an amortization formula. This page then layers in taxes, insurance, and HOA to show a fuller monthly estimate.
Does this calculator show amortization?
Yes. The schedule section shows an amortization snapshot so you can review payment, principal, interest, and remaining balance across the first part of the loan.
Why compare 15-year and 30-year mortgages?
Comparing 15-year and 30-year terms helps reveal the tradeoff between lower monthly payment and lower total interest. It is one of the most useful first-pass comparisons for home financing decisions.
Break-even framework
The only refinance formula that matters: costs divided by monthly saving
Lenders advertise rates; borrowers should interrogate months. On a $420,000 balance, dropping from 7.25% to 6.25% on a 30-year term saves roughly $275 per month in principal and interest — but $8,400 in closing costs means month 31 is the first month you are actually ahead. Sell, relocate, or pay off before then and the refinance destroyed wealth instead of building it.
Three inputs move break-even most: whether costs are paid in cash or rolled into the balance (rolling preserves cash but earns interest on the fees), whether the term restarts (a fresh 30-year schedule can add six figures of lifetime interest even at a lower rate), and whether escrow items like taxes and insurance change at funding. Model the pessimistic version of all three in the calculator above before requesting a Loan Estimate.
Program picker
Rate-and-term, cash-out, streamline: which refinance fits your equity?
Rate-and-term: best for lowering rate or shortening term with 20%+ equity; cleanest pricing and fastest break-even.
Cash-out: funds renovations or debt payoff at mortgage rates, but higher pricing, appraisal scrutiny, and state caps such as the Texas 80% rule apply.
FHA streamline: for existing FHA loans — reduced paperwork and often no appraisal when the payment history qualifies.
VA IRRRL: for existing VA loans — the fastest path to a lower rate with minimal documentation and the VA funding fee instead of mortgage insurance.
2026 loan-limit and cost context
Conforming limits, appraisals, and closing-cost anatomy in 2026
Conforming loan ceilings reset every year with home-price indexes — verify the current FHFA baseline and your county's high-cost ceiling before sizing a refinance, because crossing into jumbo territory changes pricing, reserve demands, and appraisal standards. Cash-out refinances face the strictest loan-to-value caps, typically 80% for conventional and lower effective proceeds once costs are netted.
Closing costs break into three buckets: lender charges (origination, points, underwriting), third-party services (appraisal, title, escrow, recording), and prepaid escrow (tax and insurance reserves plus daily interest). Only the first two are truly comparable across Loan Estimates — get at least three, compare page-two subtotals line by line, and treat any quote that hides fees in a higher rate as a more expensive loan wearing a cheaper mask. The CFPB's refinancing guide at consumerfinance.gov walks through reading a Loan Estimate and exercising the three-day right of rescission on most non-purchase refinances.
Get three Loan Estimates and compare page-two lender and third-party subtotals, not headline rates.
Ask every lender for the no-points quote alongside any buydown so break-even stays comparable.
Confirm whether the appraisal can be waived — waivers save $400–$700 and weeks of timeline.
Check the prepayment terms of the old loan and the rescission rights of the new one before signing.

FAQ
Frequently asked questions
When does refinancing a mortgage actually save money?
Refinancing saves money when the monthly saving repays total closing costs before you sell or pay off the loan. Divide costs of 2%–5% of the loan by the monthly saving to find the break-even month — a $6,000 cost with $200 monthly saving breaks even in 30 months.
What is the difference between rate-and-term and cash-out refinancing?
Rate-and-term refinancing changes the rate, term, or both without increasing the balance, while cash-out refinancing replaces the loan with a larger one and pays you the difference. Cash-out deals carry higher rates, stricter equity requirements, and in states like Texas a legal cap at 80% of appraised value.
How much does it cost to refinance in 2026?
Expect 2%–5% of the loan amount for lender fees, title, escrow, appraisal, and recording charges, with high-cost states like New York and California at the upper end. Rolling costs into the balance preserves cash but raises the amount you pay interest on, which extends break-even.
Will refinancing reset my mortgage term and cost me more?
It can. Refinancing a 30-year loan you have paid for years into a fresh 30-year term lowers the payment but restarts amortization, so total interest may rise even at a lower rate. Compare total interest on both schedules here, or consider a 20- or 15-year term to pair savings with a faster payoff.
Can I refinance with low equity or an FHA or VA loan?
Yes. FHA streamline and VA IRRRL programs let qualifying borrowers refinance with reduced paperwork and often no appraisal when the existing loan is government-backed. Conventional refinances generally want at least 20% equity to avoid PMI, though lender-paid options exist at a higher rate.
Where can I get unbiased guidance before I refinance?
The Consumer Financial Protection Bureau publishes a step-by-step refinancing guide at consumerfinance.gov covering break-even math, closing disclosures, and right-to-cancel rules. Review it alongside this calculator's numbers before signing anything a lender presents.
