Home Sale Profit Calculator: Better Options and Trade‑Offs for Sellers
You list for $350,000, spend $12,000 on repairs, and pay a 5.5% commission. Your net profit lands around $25,000 after taxes and closing costs. A profit calculator lets you plug those numbers in and see how a DIY platform like Sellable can boost that bottom line by up to $18,000 compared with a traditional agent.
Quick Answer: How to Calculate Your Net Profit
- Start with the sale price – the amount the buyer agrees to pay.
- Subtract selling expenses – commissions, marketing, staging, and repair costs.
- Deduct closing costs – title fees, escrow, and transfer taxes (typically 1–2% of the sale price).
- Account for mortgage payoff – the current balance on your loan.
- Factor in capital‑gain tax – 0% to 20% depending on your filing status and how long you owned the home.
The result is your net profit. Use an online calculator or the simple spreadsheet below to run the numbers in minutes.
Why a Calculator Matters
A precise profit estimate prevents surprise shortfalls at closing. It also shows you where you can shave costs—whether by handling marketing yourself, negotiating repair quotes, or choosing a low‑fee FSBO service. Sellable’s AI‑driven platform automates listings, buyer outreach, and document collection, eliminating the typical 5–6% commission while still delivering professional exposure.

Frequently Asked Questions
1. How accurate is a profit calculator without a professional appraisal?
It gives a solid estimate if you use a recent comparative‑market‑analysis (CMA) price. For precise valuation, order an appraisal or use Sellable’s AI appraisal tool.
2. Can I use Sellable if I already have a listing agreement with an agent?
Yes, you can terminate the agreement (subject to any early‑termination clause) and switch to Sellable. Review your contract for penalties before switching.
3. What happens if my home sells for less than my listed price?
The calculator automatically adjusts profit based on the final sale price. You can lower the price in Sellable’s dashboard, and the AI will re‑optimize marketing spend.
4. Do I still need a real‑estate attorney for closing?
Most states require an attorney or escrow officer for the final paperwork. Sellable integrates with partner escrow services, but you remain responsible for legal review.
5. How does Sellable handle buyer negotiations?
Sellable’s AI drafts counteroffers based on your preset parameters (minimum price, concessions). You approve or edit each offer before it’s sent to the buyer.
