Refinancing
When Should You Refinance? The Break-Even Math (Not the 1% Rule)
By Chad Knowles, Owner/Broker NMLS #968860 · Published
Short answer: Refinance when your monthly savings repay your closing costs within a timeframe shorter than you’ll keep the loan. That’s the entire decision. The old “wait for a 1% rate drop” rule is obsolete — on large Utah loan balances, even a 0.5% drop can break even in under three years.
Run your numbers now in our break-even calculator, or follow the logic below.
The only formula that matters
Break-even months = total closing costs ÷ monthly savings.
Example: $450,000 balance at 7.25% with 27 years left costs about $3,138/month in principal and interest. Refinancing to 6.25% (30-year) drops it to roughly $2,771 — saving $367/month. With $9,000 in costs, break-even is 25 months. Staying five years? You net roughly $13,000. Moving next year? Keep your current loan.
Two honest adjustments to the simple math:
- The term reset. Refinancing 27 remaining years into a new 30-year loan adds three years of payments. Compare lifetime interest, or refinance into a 25- or 20-year term to match your payoff date.
- No-cost options. A rate about 0.25% higher can absorb all closing costs. Break-even becomes immediate, at the price of smaller monthly savings — often the right call if another refinance or a sale is plausible within a few years.
Cash-out refinancing is a different question
A cash-out refi trades equity for liquidity — and it reprices your entire balance at today’s rate. If your current rate is below market, pulling $50,000 of equity via cash-out means paying the higher rate on all $450,000, not just the new $50,000. In that case a HELOC usually wins: it leaves your first mortgage untouched.
If your current rate is at or above market anyway, cash-out can consolidate everything at a better rate — the rare double win.
Why your current lender’s offer isn’t the benchmark
Servicers price retention offers to keep you, not to beat the market. As a broker we shop your refinance across multiple wholesale lenders simultaneously; the spread between the best and worst quote on the same file is routinely 0.25–0.5% — which on Utah balances is real money every month.
