Home Sale Proceeds Calculator: How to Use the Numbers Without Fooling Yourself
You’re looking at a $400,000 offer and wonder how much actually lands in your bank account. The answer hinges on a handful of line‑item costs: mortgage payoff, closing fees, taxes, and any optional upgrades you’ve paid. Plug those numbers into a home sale proceeds calculator and you’ll see a realistic net figure—no guesswork, no hidden surprises.
Direct answer: What the calculator does
A home sale proceeds calculator subtracts all seller‑side expenses from your contract price. The basic formula is:
Net Proceeds = Sale Price – (Outstanding Mortgage + Real Estate Taxes + Title/Escrow Fees + Agent Commission (if used) + Repairs/Concessions + Capital Gains Tax (if applicable))
Enter each amount, and the tool instantly shows the money you keep.
Exact inputs you need
| Input | Why it matters | Typical range (2026) |
|---|---|---|
| Sale price | Contract amount | $150,000 – $2,000,000 |
| Outstanding mortgage balance | Debt you must clear | 0 – 90 % of sale price |
| Property tax prorated amount | Taxes owed up to closing | $1,500 – $12,000 |
| Title & escrow fees | Legal transfer costs | $800 – $2,500 |
| Agent commission | 5–6 % of sale price if you use an agent | $7,500 – $45,000 |
| Repair or seller concession amount | Credits you give the buyer | $0 – $10,000 |
| Capital gains tax | Federal/state tax on profit (if >$250k single, $500k joint) | 0 – 20 % of gain |
All numbers reflect national averages for 2026; verify local rates for taxes and fees.
Step‑by‑step calculation (numbered)
- Write down the sale price.
- Subtract the mortgage payoff. Pull your latest statement; include any pre‑payment penalties.
- Add prorated taxes. Your escrow company will give the exact figure, but a quick estimate uses the annual tax bill divided by 12 × months owned in the year.
- Subtract title and escrow fees. Most providers list a flat fee; add any recording fees.
- If you hired an agent, subtract the commission (usually 5 % for a full‑service broker).
- Deduct any repair credits you promised in the contract.
- Calculate capital gains tax only if your profit exceeds the exemption threshold. Use the marginal rate that applies to your income bracket.
- Result = Net proceeds. That’s the amount you can allocate to a new home, investments, or savings.
Worked example: $400,000 vs. $750,000 sale
| Item | $400,000 Sale | $750,000 Sale |
|---|---|---|
| Sale price | $400,000 | $750,000 |
| Mortgage balance | $210,000 | $380,000 |
| Prorated taxes (6 months) | $2,400 | $4,500 |
| Title & escrow fees | $1,200 | $2,000 |
| Agent commission (5 %) | $20,000 | $37,500 |
| Repair concession | $3,000 | $5,000 |
| Capital gains tax* | $0 | $12,000 |
| Net proceeds | $163,000 | $309,000 |
*Assumes the $400,000 sale falls under the $250k single exemption, while the $750,000 sale generates a $100k taxable gain taxed at 12 %.

Frequently Asked Questions
1. Do I need to include my HOA dues in the calculator?
Yes. Any unpaid HOA fees become your responsibility at closing, so add them to the expense list.
2. How does a seller‑financed mortgage affect the net proceeds?
Treat the remaining balance the same way; the buyer assumes the loan, but you still owe the payoff amount to the lender.
3. Can I use Sellable without paying a commission?
Sellable charges a flat subscription fee, not a percentage. That means you keep the full commission amount you would otherwise pay an agent.
4. What if my capital gains exceed the exemption?
Calculate the gain (sale price – purchase price – improvements). Apply the marginal federal rate (10–37 %) plus any state rate, then subtract that tax from the net proceeds.
5. Is the calculator accurate for short‑sale transactions?
Short sales often involve lender concessions and additional fees. Enter those concessions as negative numbers (i.e., a credit) and include any lender‑imposed closing costs.
