Extra payments vs refinance
These options look similar because both can save interest, but a new loan solves a different problem than extra principal on the current loan. This page compares them over the same hold period so you can see when the cheaper-looking path actually changes once timing and costs are aligned.

Use the same hold period for both options
The most common mistake is comparing extra payments over a short horizon with a refinance over the full term. Use the same hold period for both. If you expect to move, refinance again, or redirect cash in five years, then both options should be judged inside that same window.
Use this guide when you are deciding between faster payoff and refinancing
- Stay here if the real question is whether to accelerate the current loan or replace it with a new one.
- Move next to extra mortgage payments if you already know you want to keep the current loan.
- Move next to refinance break-even if the new-loan path is clearly the front-runner.
What extra payments do well
- They reduce principal without triggering a new set of closing costs.
- They are flexible because you can usually increase, reduce, or pause them.
- They work best when the current rate is already acceptable and the main goal is faster payoff.
What a refinance is really for
- It can lower the required payment, change the term, or replace the rate structure.
- It introduces a new cost stack: fees, credits, escrow resets, and timing risk.
- It makes more sense when the new loan solves a different problem than simple acceleration.
Why the decision can flip
A refinance can look better when you spread closing costs over 20 or 30 years. The decision can flip once you shorten the horizon, include the upfront cash, or realize that you may not keep the loan long enough to recover the costs. Extra payments often look less dramatic in the first spreadsheet but win when the time window is short or uncertain.
A practical comparison sequence
- Model the current loan with no changes.
- Add the extra payment amount you can sustain right now.
- Model the refinance with realistic fees, credits, and the actual new payment.
- Compare both options over the same hold period, not over two different timelines.
Route the next question correctly
If your goal is "lower my payment," you probably need the refinance break-even path. If your goal is "be done sooner while keeping flexibility," stay with the extra payment calculator. If you are unsure whether the cash is even available, detour through the liquidity reserve check.
