The short answer
Last updated: July 2026
To compare mortgage points with a lender credit, use the same loan amount and term, then add the points paid to interest through your expected holding period and subtract the lender credit from the competing offer’s interest. Compare payments, remaining balances, and the crossover month against the Loan Estimates; the lowest upfront cash is not always the lowest holding-period cost.

Compare the closing-cost tradeoff on one horizon.
Hold the loan amount and term constant. The model compares scheduled interest plus points with scheduled interest minus the lender credit; it does not calculate APR or replace lender disclosures.

How it works
How this tool works.
Points and lender credits move cost between closing and the life of the loan. A discount-point offer usually asks for more cash at closing in exchange for a lower rate, while a lender-credit offer generally offsets some closing costs in exchange for a higher rate. The exact relationship is lender- and offer-specific, so compare written disclosures issued on the same day and for the same loan structure.
This calculator isolates that pricing decision. It amortizes both offers, counts interest through the holding period you enter, adds points to the lower-rate scenario, and subtracts the entered lender credit from the other scenario. It excludes third-party costs, taxes, insurance, prepaid items, APR adjustments, opportunity cost, tax treatment, and any difference not represented in the inputs.
1
Enter the common loan amount and term, then copy each offer’s note rate, discount points, or lender-credit dollars from comparable Loan Estimates.
2
Choose a realistic holding period; the model calculates monthly principal and interest, cumulative interest, and remaining principal for both offers through that month.
3
Compare the modeled financing cost: points plus interest for the points offer versus interest minus the lender credit for the credit offer.
4
Review the crossover month, rerun a shorter and longer holding period, and reconcile every result to the lender disclosures before choosing an offer.
Make the result useful
Compare pricing on one loan structure and one time horizon
A valid comparison holds the loan amount, term, product type, lock period, occupancy, property, down payment, and other underwriting facts constant. If one disclosure has a different term, loan type, mortgage-insurance structure, or cash-out amount, the difference is larger than points versus credits. Normalize the offers or label the mismatch before relying on the result.
The model treats points as an upfront financing cost and lender credits as an upfront cost offset. It then calculates scheduled interest through the entered month. That method preserves the remaining-balance difference instead of calling every dollar of principal a cost. It still leaves out the time value of upfront cash, possible tax effects, and costs that appear elsewhere on the disclosure.
A crossover is only useful when it falls inside a holding period you can plausibly reach. If you may sell or refinance before the crossover, paying points can fail to recover its added cash cost. If you expect to hold much longer, a lower rate can keep producing interest savings after the simple crossover. Run multiple horizons and keep the dated offer documents with the decision.
The assumptions that move this result
Loan amount
The principal used for both offers and as the points basis in this model.
Loan term
The shared amortization period; offers with different terms are not isolated points-versus-credit comparisons.
Points-offer rate and points
The note rate and discount points for the higher-upfront-cost offer, with one point modeled as one percent of the loan amount.
Credit-offer rate and lender credit
The note rate and dollar credit for the lower-upfront-cost offer, copied from the same-day written disclosure.
Holding period
The month when the model compares cumulative scheduled interest and remaining principal.
Calculation lens
Points scenario cost = loan amount x points percent + scheduled interest through the holding month. Credit scenario cost = scheduled interest through the holding month - lender credit. The crossover is the first scheduled month when the points scenario cost is no greater than the credit scenario cost.
The output is a same-loan pricing scenario showing principal-and-interest payments, scheduled interest, remaining balances, horizon cost, and a modeled crossover. It is not an APR, approval, rate lock, disclosure, tax conclusion, or recommendation.
Read the number in context
The owner expects to refinance again soon
A lower-rate offer can show a smaller payment but still cost more at a short horizon because the added points have not been recovered. Compare the likely refinance month with the crossover and include any other non-common loan costs separately.
The credit preserves closing liquidity
A lender credit can reduce cash needed at closing even when its longer-horizon modeled cost is higher. Treat liquidity as a separate decision constraint, not as proof that the higher-rate offer is cheaper.
The model assumes fixed-rate, fully amortizing monthly payments and constant inputs. It excludes APR, adjustable-rate changes, prepaid interest, mortgage insurance, taxes, insurance, escrow, third-party fees, financed costs, opportunity cost, tax effects, curtailments, late payments, recasting, and lender-specific rounding. The current lender disclosures control.
Before you act
• Use Loan Estimates issued for the same loan amount, term, product, lock period, occupancy, property, and day.
• Copy points and lender credits from the actual disclosures rather than an advertisement.
• Compare cash to close and every non-common fee outside this isolated model.
• Run expected, shorter, and longer holding periods.
• Inspect both payment and remaining principal at each horizon.
• Confirm the selected pricing and rate-lock terms before closing.
Keep the decision reconstructable
Save both dated Loan Estimates, the entered assumptions, the expected holding-period rationale, the crossover result, and the reason liquidity or other costs affected the final choice. A future reviewer should be able to reproduce the comparison without relying on a remembered sales conversation.
Questions landlords ask
Questions about this tool and its limits.
Are mortgage points and lender credits opposites?
They are two ways of trading upfront cost against rate, but they are not guaranteed mirror images. One point is one percent of the loan amount used by this model. A lender credit is entered as a dollar amount. The actual rate and pricing relationship comes from the lender’s written offer.
What does the crossover month mean?
It is the first modeled month when the cumulative interest saved by the points offer is large enough to recover both the points paid and the lender credit forgone. It is not a recommendation because selling, refinancing, prepaying, taxes, opportunity cost, and other closing-cost differences can change the decision.
Why does the calculator compare interest instead of total payments?
Principal repayment builds equity and reduces the remaining debt, so counting all principal as a financing cost would distort the comparison. The tool reports payments and remaining balances separately while using interest plus or minus the entered pricing amounts for its modeled cost comparison.
Does this replace the APR or Loan Estimate?
No. The calculator models only the inputs shown and does not calculate Regulation Z APR, finance charges, prepaid interest, mortgage insurance, adjustable-rate changes, escrow, taxes, or every closing cost. Use the Loan Estimates and Closing Disclosures as the authoritative offer records.
