Mortgage Points vs. Zero Points: Calculate the Break-Even Before Closing

As of 2026⁠-⁠08⁠-⁠09 | United States | USD | General education, not individualized financial, investment, tax, legal, credit, benefits, mortgage, or retirement advice.

Discount points exchange cash at closing for a lower interest rate. They are not automatically a discount and do not guarantee savings. The decision depends on the exact rate reduction, loan balance, monthly savings, taxes, opportunity cost, and how long the borrower actually keeps the loan.

The decision in one minute

One point equals 1% of the loan amount, so one point on $300,000 costs $3,000. In the example, moving from 6.50% with zero points to 6.25% with one point lowers monthly principal and interest from $1,896.20 to $1,847.15, a $49.05 saving. The simple break-even is about 61.16 months before taxes, lost cash yield, refinance, sale, or balance changes.

• Compare same-day offers with the same loan type, amount, term, lock period, and lender-credit assumptions.
• Calculate the exact cash cost and monthly payment difference from the written Loan Estimates.
• Use the expected time until sale, refinance, payoff, or recast, not the contractual maturity alone.
• Preserve closing reserves; a theoretical break-even is weak if points consume the emergency cushion.

The practical comparison is not a slogan about which option is always better. It is a controlled test: use the same amount, dates, jurisdiction, household constraints, and risk window on both sides. Replace every illustrative input below with the current written terms that apply to you before acting.

What the official sources establish

CFPB guidance defines discount points as upfront fees paid in exchange for a lower interest rate and notes that one point equals 1% of the loan amount.

Points and lender credits are opposite pricing choices: borrowers can pay more upfront for a lower rate or accept a higher rate in exchange for a credit toward closing costs.

The rate reduction for a point is not fixed by law and can vary by lender, market, loan type, lock period, and day. Actual Loan Estimates are required for the comparison.

A simple cost divided by monthly savings break-even omits present value, taxes, opportunity cost, declining interest, and a transaction that ends the loan early.

These are rule and program boundaries, not a quote or forecast. Government pages can change, issuer or plan documents can be narrower, and future returns, inflation, income, tax law, eligibility, and household needs are unknown. The checked date is part of the evidence.

A reproducible comparison

This model is deliberately simple enough to audit. It is an illustration, not a prediction. Its purpose is to expose the inputs that control the decision and make it obvious where a personal document or live quote must replace an assumption.

simple-break-even

Formula: 3000 / (1896.20 - 1847.15) = 61.16

Outputs: {"simpleBreakEvenMonths":61.16,"simpleBreakEvenYears":5.10}

Units: months and years. Rounding: two decimals.

The simple break-even is just over five years. It is not a promise because it ignores the time value of $3,000, possible tax treatment, a changing balance, early payoff, and whether the loan ends. Compare cumulative cash flows through the realistic loan-retention date.

Case for paying discount points

Points can reduce the contractual payment and interest when the borrower keeps the loan beyond a robust break-even. They may fit a long expected tenure with ample closing cash and no strong competing use for the funds.

The upfront cost is generally unrecoverable after an early sale or refinance. A lower displayed rate can distract from a high point price or other lender fees, so APR and cash-to-close remain essential.

Case for choosing zero points

Zero points preserves cash and avoids betting on a long loan-retention period. It can be sensible when the borrower expects to move, refinance, make a large payoff, or values reserves more than the modeled payment reduction.

The tradeoff is a higher payment and interest if the loan persists. Cash preserved at closing has value only if it remains available or is used for a higher-priority purpose.

What can flip the answer

• The exact point cost and rate reduction on same-day Loan Estimates.
• Expected sale, refinance, payoff, recast, or loan modification date.
• Cash needed for reserves, repairs, moving, debt payoff, or a larger down payment.
• Marginal tax treatment and whether mortgage interest or points are deductible under current rules.
• Opportunity cost and the risk-free yield available on preserved cash.

Run at least a base case, a less favorable case for the initially preferred option, and a household-stress case. If a modest change reverses the result, the responsible conclusion is that the choice is close. A split, a shorter commitment, or a documented review date can be more robust than forcing a winner.

Downside and failure cases

• Using a lender’s verbal break-even without reproducing it.
• Comparing offers from different days or with different lock periods.
• Draining post-closing reserves to buy a lower rate.
• Assuming the loan will last 30 years despite a likely move or refinance.
• Treating tax deductibility as automatic or immediate.

A lower payment, larger projected balance, or tax advantage is not enough by itself. Liquidity, sequence risk, reversibility, behavioral follow-through, fees, legal ownership, beneficiary or survivor effects, and the cost of being wrong belong in the same comparison. No return, approval, forgiveness, tax outcome, benefit, or savings amount is guaranteed.

Price the do-nothing option

Waiting can expose the borrower to rate and property risk, but a rushed lock can be more costly. Use a short written-offer window and ask lenders to price zero points, one point, and a credit option at the same time.

Doing nothing can be rational for a short verification window, but it should have an owner and an end date. Write down what evidence is missing, who will obtain it, and the date the decision reopens. Otherwise delay becomes an unmeasured option with hidden cost.

Keep the dated documents used for the comparison. Record whether a number is guaranteed, fixed, variable, estimated, projected, taxable, deductible, refundable, vested, revocable, liquid, or subject to a deadline. If two offers or calculators define a field differently, normalize them before comparing.

A bounded action sequence

• Request same-day Loan Estimates at multiple point levels.
• Normalize term, loan amount, rate type, lock, fees, and credits.
• Calculate payment and cumulative savings by month.
• Add opportunity cost and a conservative early-exit date.
• Check cash remaining after closing and a repair reserve.
• Choose the pricing option that remains favorable before the conservative exit date.

Stop before signing, transferring, redeeming, converting, enrolling, changing withholding, or making an irreversible election if a required document is missing or the live terms differ materially from the example. Ask the relevant administrator or agency for written clarification. For a material tax, legal, benefits, credit, or investment consequence, use a qualified professional who can review the full facts.

Conflicts, compensation, and scope

MoneyMaxx did not receive affiliate, lender, bank, broker, issuer, plan, adviser, employer, servicer, lead-generation, referral, or sponsor compensation for this comparison. No named commercial product is ranked or endorsed. Official sources support general rules; the numerical case is labeled and reproducible.

This guide cannot see your full cash flow, contracts, tax return, filing status, basis, state law, credit file, health costs, estate plan, employment terms, plan document, risk capacity, or family obligations. Those omissions are decision inputs, not fine print.

Final stress test before acting

• Refinance or sell 24 months earlier than expected.
• Charge the point cost an after-tax safe-cash yield.
• Remove any assumed federal tax benefit.
• Reduce the rate discount delivered by one point.
• Reserve six months of housing costs before spending cash on points.

Points are a dated cash-flow trade, not a status symbol. Pay them only when written pricing, a conservative retention period, and adequate reserves make the cumulative break-even durable.
