Closing Cost Incentive Calculator (user-entered allocation)
Independent consumer calculator. Not affiliated with any government agency, lender, builder, MLS, appraisal district, tax authority, or other service provider unless expressly identified on the relevant placement.
A builder or seller closing-cost credit is a written promise of dollars toward the buyer's side of the closing statement — but the headline amount is not automatically the amount that reaches your closing costs. Program rules, the transaction, and the actual cost list decide what the credit can touch. This calculator takes the credit and cost lines you transcribe from your own documents, walks the credit down the lines you flagged from those documents, and shows the modeled allocation, the unallocated remainder, and the modeled cash-to-close change. Lines you flag as unknown are never numbered — they show cannot determine, because that answer belongs to your lender, not to arithmetic.
This is a user-entered allocation scenario, not an eligibility, compliance, underwriting, lending, tax, or legal result. Credit rules vary by loan program, transaction, provider, and location. Confirm eligible costs and excess-credit treatment with the lender and settlement provider.
Worked example
Worked example: a $12,000.00 written credit against five transcribed cost lines
Modeled allocated credit
$12,000.00
Unallocated (possible excess) credit
$0.00
| Cost line | Amount | Your flag | Modeled allocation |
|---|---|---|---|
| Lender origination charges | $3,200.00 | eligible (your flag) | $3,200.00 |
| Discount points | $4,500.00 | eligible (your flag) | $4,500.00 |
| Title and settlement services | $2,400.00 | eligible (your flag) | $2,400.00 |
| Prepaid taxes and insurance | $3,800.00 | eligible (your flag) | $1,900.00 |
| Down payment | $40,000.00 | not eligible (your flag) | $0.00 |
| Modeled allocated credit | $12,000.00 |
The $12,000.00 credit walks the flagged lines in listed order and covers $12,000.00 of the $13,900.00 the buyer flagged from their documents, leaving $0.00 unallocated. The modeled cash-to-close change is -$12,000.00 under this scenario. The down-payment line receives nothing because the buyer flagged it not eligible in their documents — the flag is the buyer's transcription, not this page's conclusion. Every figure is a user-entered allocation scenario under these inputs.

The math
How the math works
The credit walks your cost lines in listed order. For each line you flagged eligible in your documents, the modeled allocation is the smaller of that line's amount and the credit still remaining, and the remaining credit shrinks by that amount. Lines you flagged not eligible receive zero. Lines flagged unknown receive no number at all and switch the result to the cannot determine state. The modeled allocated credit is the sum of the line allocations; the unallocated credit is the written credit minus that sum, floored at zero; and the modeled cash-to-close change is the negative of the allocated credit. All money values round half-up to cents. An empty cost list produces the incomplete state instead of a number.
Fine print
Assumptions and limitations
- Every dollar amount and every eligibility flag is user-entered from your own documents. Nothing is pulled from a lender, title company, program database, or rate sheet, and nothing is verified.
- The allocation is pure arithmetic on your flags. It is not an interested-party-contribution calculation, a program-limit check, or a compliance review, and it never decides what a credit may be applied to.
- Unknown flags produce the cannot determine state and an empty cost list produces the incomplete state — never a partial or guessed figure.
- The modeled cash-to-close change ignores timing, escrow, prepaid-interest per-diem changes, rate or points trade-offs, and every other term of the loan.
- This is a user-entered allocation scenario, not an eligibility, compliance, underwriting, lending, tax, or legal result. Credit rules vary by loan program, transaction, provider, and location. Confirm eligible costs and excess-credit treatment with the lender and settlement provider.
Confirm-eligibility checklist (questions, not determinations)
- Which of these cost lines may the credit be applied to under my loan program, per the lender in writing?
- How is credit beyond the applicable costs treated — reduced, reallocated, or lost — and where will that appear on the Closing Disclosure?
- Does the loan program cap contributions from the builder or seller for my transaction, and what is the cap the lender applies?
- Is the credit stated in the purchase contract or addendum exactly as the lender expects to see it?

Answers
Frequently asked questions
What is a closing-cost credit from a builder or seller?
It is money the builder or seller agrees, in the purchase contract or an addendum, to put toward costs on the buyer's side of the closing statement — items such as lender charges, title and settlement services, prepaid taxes and insurance, or discount points. The written agreement and the loan program's rules control what the credit can actually touch, and the headline dollar amount is not automatically the amount that reaches the closing statement.
Why does the tool ask me to flag each cost myself?
Because which costs a credit may be applied to is decided by the loan program, the lender, and the transaction documents — not by generic arithmetic. This calculator only allocates dollars across the lines you flagged from your own documents. It never determines eligibility, and any line you flag as unknown is excluded from the numbers and shown as cannot determine.
What does the cannot determine state mean?
It appears whenever at least one cost line carries an unknown flag. The calculator refuses to model a number for that line rather than guessing, because a guessed allocation could be mistaken for a lender decision. The fix is a question, not a formula: ask the lender and settlement provider how each unknown line is treated, then update the flag.
What happens to credit that is larger than my listed costs?
The model shows it as unallocated credit and raises a mismatch warning. In real transactions, loan programs cap contributions from interested parties such as builders and sellers, and credit beyond the costs actually on the closing statement may be restricted, reallocated, reduced, or lost. For example, the Fannie Mae Selling Guide describes interested-party contribution boundaries that vary by transaction. This tool never computes or applies a cap — it only flags the mismatch for you to verify.
Where should the cost lines come from?
From your own written documents: the Loan Estimate your lender provides, the builder's or seller's credit addendum, and any cost worksheet from the title or settlement company. The Consumer Financial Protection Bureau publishes explainers for the Loan Estimate and Closing Disclosure that show where each charge and each credit appears. Record the source document and its date with the scenario, because the numbers change between document versions.
