Seller Closing Costs Calculator: Real Costs, Fees, and Net‑Proceeds Math
$12,300 – that’s the average amount a seller pays in closing costs on a $400,000 home in 2026. Knowing the exact numbers lets you set a realistic asking price, avoid surprise deductions, and keep more of your sale profit. Below you’ll find a step‑by‑step calculator, real‑world examples for $400k and $750k houses, and a quick‑reference table that works in any state.
What sellers actually pay at closing
In 2026 the typical seller’s closing‑cost bill ranges from 1.5 % to 2.5 % of the sale price. The bulk comes from real‑estate commissions (5 %–6 % split between buyer’s and seller’s agents), title‑transfer fees, escrow fees, and prorated property taxes. When you run the numbers, the net proceeds equal the contract price minus these costs plus any buyer‑paid items (like a repair credit).
Quick‑look cost table (2026 averages)
| Sale price | Commission (5.5 %) | Title & escrow | Transfer tax* | Prorated taxes | Total closing costs | Net proceeds* |
|---|---|---|---|---|---|---|
| $400,000 | $22,000 | $1,600 | $1,200 | $1,500 | $26,300 | $373,700 |
| $750,000 | $41,250 | $3,000 | $2,250 | $2,800 | $49,300 | $700,700 |
*Transfer tax varies by state; the figures above use the national median (0.30 % of price). Net proceeds assume no buyer credits or seller concessions.
How to calculate your own closing costs
- Start with the contract price.
- Apply the commission rate you’ve negotiated (5 %–6 %). Most FSBO sellers on Sellable (sellabl.app) choose a flat 5.5 % to stay competitive while saving the buyer’s‑agent fee.
- Add title‑insurance and escrow fees. 2026 national average: 0.40 % of the price.
- Insert the state transfer tax. 0.20 %–0.60 % of the price; check your local recorder’s office.
- Prorate property taxes up to the closing date. Look at last year’s tax bill and divide by 12 months.
- Subtract any buyer‑paid items (e.g., inspection repairs).
Formula:
Net proceeds = Sale price – (Sale price × Commission%) – (Sale price × 0.40% Title/Escrow) – (Sale price × TransferTax%) – ProratedTaxes + BuyerCredits
Example 1: $400,000 home in Missouri
Assumptions (May 2026):
- Commission 5.5 %
- Title/escrow 0.40 %
- Missouri transfer tax 0.25 %
- Annual property tax $1,800, closing on June 15 (5.5 months of tax)
| Item | Calculation | Amount |
|---|---|---|
| Commission | 400,000 × 5.5 % | $22,000 |
| Title & escrow | 400,000 × 0.40 % | $1,600 |
| Transfer tax | 400,000 × 0.25 % | $1,000 |
| Prorated taxes | 1,800 ÷ 12 × 5.5 | $825 |
| Total costs | — | $25,425 |
| Net proceeds | 400,000 – 25,425 | $374,575 |
Example 2: $750,000 home in California
Assumptions (May 2026):
- Commission 5.5 %
- Title/escrow 0.40 %
- California transfer tax 0.55 % (county‑specific)
- Annual property tax $9,600, closing on July 1 (6 months)
| Item | Calculation | Amount |
|---|---|---|
| Commission | 750,000 × 5.5 % | $41,250 |
| Title & escrow | 750,000 × 0.40 % | $3,000 |
| Transfer tax | 750,000 × 0.55 % | $4,125 |
| Prorated taxes | 9,600 ÷ 12 × 6 | $4,800 |
| Total costs | — | $53,175 |
| Net proceeds | 750,000 – 53,175 | $696,825 |
These two scenarios illustrate how state‑specific taxes swing the bottom line. Using Sellable’s built‑in calculator eliminates guesswork and shows you the exact net proceeds before you list.
