Rate-drop scenarios

Refinancing from 7.75% to 6.75% on $250,000: is it worth it?

On these stated assumptions, refinancing from 7.75% to 6.75% comes out about $12,428 ahead over a 7-year stay after $4,600 of closing costs.

Full-point drop on a $250,000 balance, 20 years left refinanced into a matched 20-year term.

Pre-built example: this page runs on the stated assumptions below, not on a live market quote. It is not today's quote for anyone. Change the balance, years left, term, closing costs, and stay to your own numbers in the Stay or Refi Calculator before drawing any conclusion.

The stated example

Every number below uses this page's own stated example: a $250,000 balance, 20 years left on the current loan, a new 20-year term, $4,600 of closing costs, and a 7-year stay. Change any of those and the answer can change with it. These are worked examples, not rate quotes.

What drives this particular drop

This is a 1 percentage point drop on a $250,000 balance, which saves $151 a month before costs. Savings scale roughly with balance, while closing costs mostly do not. Halve the balance and roughly the same fee stack has to be repaid from about half the monthly saving, which stretches break-even far beyond the month shown here. Double the balance and the same fees are repaid much sooner. That scaling is why a drop that wins comfortably in this set can fail on a smaller loan with a full fee stack, and why the fee fight matters more as the drop gets smaller.

The second driver here is what does not happen: there is no term restart. This example trades 20 years left for a 20-year term, so the payoff date stays fixed and none of the payment saving is bought with extra years of payments. That makes the comparison unusually clean: the whole difference between the two columns is the rate. Read the lifetime interest line alongside the payment line, because both loans end on the same date and the lower rate simply keeps more money in the household on the way there.

How sensitive is the answer to closing costs?

Hold every other input at the stated example and vary only the fee stack. This is the negotiation table to bring to a lender: it shows what each thousand dollars of fees does to the same rate drop.

How sensitive is the answer to how long you stay?

Keep the stated $4,600 of closing costs and vary only the stay. Break-even does not move; whether you reach it does. A household that might move in three years should judge this drop on the first row, not the last.

How to judge this drop on your loan

• Scale the balance. Savings grow roughly in proportion to balance; closing costs mostly do not.
• Get the closing cost figure from a Loan Estimate, not an advertisement, and rerun the break-even.
• Ask for the same rate on a term that matches your years left. The payment saving shrinks; the interest saving usually grows.
• Test your earliest realistic move date, not your longest possible stay. The horizon table above shows how quickly the verdict can flip.

How to read this case

This is the cleanest structure on the page: the term-matched refinance. The current loan has 20 years left and the new loan runs 20 years, so the payoff date does not move. That single choice removes the term restart debate entirely and lets the rate drop do all the talking. Every dollar of payment difference between the two loans comes from the interest rate, not from re-spreading the balance, which makes the break-even and the interest comparisons over the stay unusually honest.

The balance works against the borrower a little and the drop works for them a lot. On $250,000, a full-point reduction returns fewer monthly dollars than the same drop on a larger loan, but a full point is a deep cut, and the closing costs here are moderate. The balance-size rule cuts both ways: small loans need either a big drop or low costs to clear break-even quickly, and this case has one of the two plus disciplined costs. It is a good template for what a smaller-balance borrower should insist on before applying.

Term matching also changes what the monthly saving means. In a restart refinance, part of the lower payment is borrowed from your future self in the form of extra years. Here, the payment falls while the finish line stays fixed, so the saving is unambiguous: same debt-free date, less interest paid on the way there. The full-loan interest table shows the effect plainly, because both loans end on the same date and the lower rate simply keeps more money in the household across the whole road.

The coaching point is to protect the match. When a borrower with 20 years left is quoted a fresh 30-year term because the payment looks lower, that is a different product being sold on the payment rather than the outcome. If a lender's best rate is only offered on a 30-year term, compare it honestly anyway, using the calculator with each term, and look at total interest over your stay and to payoff rather than the monthly figure alone. On the assumptions stated here, the matched term is the structure that turns a rate drop into unambiguous progress.
