The Formula is Simple

Costs ÷ Savings = Months to break even. You can do this math in seconds.

2-3 Year Rule of Thumb

If your break-even is under 2-3 years, paying for a lower rate usually makes sense.

Your Timeline Matters Most

The decision depends entirely on how long you plan to keep the mortgage.

What is the Break-Even Point?

The simple calculation that helps you compare mortgage options.

The break-even point is when your accumulated monthly savings equal the extra upfront costs you paid. It answers the question: "How long until this investment pays off?"

When comparing two mortgage options, one typically has a lower interest rate (lower monthly payment) but higher closing costs. The other has a higher rate (higher payment) but lower costs. The break-even calculation tells you exactly when Option A becomes cheaper than Option B—and by how much.

Example:
$5,000÷$200/month=25 months

After 25 months, you've recouped your investment. Every month after is pure savings.

The Tradeoff

Lower Rate vs. Lower Costs

Every mortgage decision involves this fundamental tradeoff. Here's how to think about it.

Pay for Lower Rate

Higher costs upfront

  • Lower monthly payment forever
  • Less total interest over loan life
  • Better if staying long-term (5+ years)
  • Higher upfront cash needed
  • Longer break-even period
Best For:

Homeowners planning to stay 5+ years, with cash to spare beyond down payment and reserves.

Take Higher Rate

Lower costs upfront

  • Lower closing costs or lender credits
  • Keep more cash in your pocket
  • Better if moving soon or uncertain
  • Higher monthly payment
  • More interest if you stay long
Best For:

Buyers uncertain about timeline, tight on cash, or planning to move/refinance within 3-5 years.

The Key Insight

Neither option is inherently better—it depends entirely on your timeline. The break-even calculation removes the guesswork and tells you exactly which option saves you money based on how long you plan to keep the mortgage.

When to Pay Points vs. When to Skip

A simple decision framework based on your situation.

Pay for Lower Rate When...

  • You plan to stay 5+ years
  • You have extra cash beyond down payment and reserves
  • Rates are historically attractive
  • Your break-even is under 3 years
  • You value predictable savings over investment flexibility

Skip Points When...

  • You might move within 3-5 years
  • You need to minimize upfront costs
  • You're uncertain about your timeline
  • Rates might drop further, making refinance likely
  • Your break-even exceeds your expected stay
Common Pitfalls

Avoid These Mistakes

Four common errors that lead to poor break-even decisions.

Ignoring Opportunity Cost

The cash you use to buy points could be invested elsewhere. If you could earn 6% annually on that money, factor that into your calculation. True break-even might be longer than the simple formula suggests.

Not Accounting for Future Refinance

If rates drop 1% next year and you refinance, you lose the benefit of points you paid. Consider rate trends and the likelihood of refinancing when deciding.

Using Wrong Cost Numbers

Only include non-refundable costs in your calculation. Don't include prepaid taxes, insurance escrow, or per-diem interest—those aren't truly "costs" of the lower rate.

Forgetting Tax Implications

Points paid at purchase are tax-deductible that year (if you itemize). A higher rate means more interest = larger deduction. The after-tax math might differ from the pre-tax calculation.
