Discount points are one of the few levers at closing that change your rate for the entire life of the loan. Whether they are worth pulling depends on a single comparison: the upfront cost against the monthly saving, measured over how long you will actually keep the loan.

The short answer

Break-even months = cost of the points ÷ monthly payment saving. If you expect to stay — or keep the loan — longer than that, points can pay off. If you might sell or refinance sooner, the math often argues for keeping the cash.

The framework

  1. Ask for a loan estimate with and without points. The difference in rate and closing cost should be itemized.
  2. Compute the monthly saving at each rate, using the same loan amount and term.
  3. Divide cost by saving to find the break-even month.
  4. Compare that to your time horizon. Shorter than the break-even? Points likely lose.
  5. Consider the cash. Money spent on points is not available for an emergency fund, repairs, or other goals.
  6. Confirm the rate is fixed for the period you care about, so the saving is real.

A hypothetical illustration

Figures are illustrative and rounded, not quotes, and are shown so the arithmetic is checkable.

  • No points: $300,000 at a fixed 6.5% interest rate for 30 years → principal and interest ≈ $1,896.20 monthly.
  • One point: pay $3,000 upfront (1% of the loan) for an illustrative fixed 6.25% rate → payment ≈ $1,847.15 monthly.
  • Monthly saving: about $49.05.
  • Simple cash-flow break-even: $3,000 ÷ $49.05 ≈ 61.2 months, with the initial outlay recovered during month 62.

This assumes monthly amortization, an unchanged balance/term between offers and no other fee difference. One point does not buy a standard quarter-percentage-point reduction: the offered rate reduction varies. The rates above are interest rates, not fee-inclusive APRs.

Compare more than a break-even date

Ask for otherwise comparable Loan Estimates, including an option with no points and any lender-credit option. Separate discount points from other origination charges. If other costs change, use the net upfront cost difference, not just the line labeled points.

Consider staying with the loan for two, five and ten years. For each horizon, compare upfront costs, payments and remaining principal, then consider how valuable the cash reserve is to you. The simple payment-saving calculation omits investment opportunity cost and differences in remaining loan balances. A later refinance ends the benefit of the old rate even if you remain in the same house.

Costs and limitations

  • Upfront cash is gone and reduces your reserves.
  • Time horizon risk: selling or refinancing early can strand the benefit.
  • Rolling points into the loan raises your balance and total interest.
  • Other closing costs may change alongside the rate — compare the full loan estimate.
  • No guaranteed recommendation. Points are a comparison, not a universal answer.

Your checklist

  • Request loan estimates with and without points.
  • Identify the exact cost and the rate reduction.
  • Compute the break-even month yourself.
  • Compare it against your expected time in the home.
  • Confirm you still have an emergency fund after closing.
  • Ask whether the seller can contribute to points.
  • Verify the rate type is fixed as you expect.
