Closing costs are the price of the transaction — not the house
Your down payment buys equity: it’s your ownership stake. Closing costs pay for everything required to make the transaction happen — the lender’s work, the title company’s work, the appraisal, the recording, and the first dollops of tax and insurance. That’s why they’re quoted separately, and why the rule of thumb is 2–5% of the purchase price, on top of whatever you put down. On the defaults, the math comes to $7,383 — $80,000 of down payment and $7,383 of costs are two different piles of money you need on signing day: $87,383 total.
Output · formula · meaning
| Output | Formula | What it means |
| Loan amount | price − down payment | The base most fees scale from: $320,000 on the defaults. |
| Origination fee | 0.75% × loan | The lender’s charge for making the loan: $2,400 on the defaults. Often the single biggest line item. |
| Discount points | points × 1% × loan | $0 on the defaults. One point ($3,200) buys roughly a 0.25% rate cut for the life of the loan. |
| Title insurance (lender’s) | $4.50/$1,000 on the first $100k + $3.50/$1,000 after | Protects the lender against title defects: $1,220 on the defaults ($450 + $770). |
| Prepaid interest | loan × APR × days ÷ 365 | Interest from closing day to month-end: $854.79 for 15 days at 6.5%. Close on the 28th instead and this line nearly vanishes. |
| Escrow (tax + insurance) | months × (1.1% of price ÷ 12) + months × $150 | The lender’s up-front cushion: $733.33 tax + $300 insurance on the defaults. |
| Lender credit | flat dollar amount off the total | $0 on the defaults. Credits lower closing costs in exchange for a higher rate. |
| Total closing costs | sum of all lines − credits | The full second bill: $7,383 on the defaults — about 1.8% of the $400,000 price. |
| Total cash to close | closing costs + down payment | What your bank account actually needs: $87,383 on the defaults. |
Worked example: closing on a $400,000 house
Price $400,000, 20% down ($80,000), so the loan is $320,000 at 6.5%, no points, no lender credit, closing mid-month (15 days prepaid), 2 months of escrow. The lines: origination $2,400 (0.75% of $320,000); appraisal $500; inspection $350; title search $250; title insurance $1,220 ($4.50 × 100 on the first $100k + $3.50 × 220 on the rest); attorney/settlement $650; recording $125; prepaid interest $854.79 (320,000 × 0.065 × 15 ÷ 365); tax escrow $733.33 (2 × 0.011 × 400,000 ÷ 12); insurance escrow $300. Sum: $7,383 — add the $80,000 down payment and you walk in with $87,383. One point of discount would have added $3,200 to the bill and cut the rate roughly a quarter point.
Who uses this
- First-time buyers: learning that “20% down” really means 20% plus another 2–5% in costs.
- Offer negotiators: deciding how much seller concession to ask for and whether to shop title fees.
- Refinancers: the same fee structure applies when you refi — this is what the refinance break-even calculator divides by the monthly savings.
- Students & researchers: a line-by-line model of what a real Loan Estimate contains, with every formula shown.
Accuracy & limitations
This is a standardized estimate, not a Loan Estimate. Real fees vary by state, county, and lender: state/local transfer taxes (some states charge over 1% of the price) are not included because they swing too widely, and an owner’s title policy — the optional policy that protects you rather than the lender — is left out. The title-insurance bands, the 0.75% origination, and the escrow conventions are typical industry figures; your lender’s Loan Estimate is the authoritative number and is legally required within three business days of your application. Figures round to whole dollars; nothing here is lending or tax advice.
Model the monthly payment in the mortgage calculator, see how closing costs eat into a refi in the refinance break-even calculator, check whether the whole package fits your income in how much house you can afford, and read how closing costs are calculated for the negotiability and tax rules behind each line.
