House Sale Profit Calculator: Real Costs, Fees, and Net‑Proceeds Breakdown
Hook: If you list a $450,000 home today and close in 45 days, you could walk away with $368,000–$382,000 after every mandatory cost and optional service fee is accounted for.
Quick‑Answer Overview
A house‑sale profit calculator subtracts three groups of expenses from your sale price: mandatory transaction fees, optional service costs, and post‑sale obligations. Plug your price, estimated closing date, and chosen service level into the table below and you’ll see a realistic net‑proceeds range within seconds.
1. Mandatory Transaction Fees (Never Negotiable)
| Fee | Low End | Typical | High End | How It’s Calculated |
|---|---|---|---|---|
| Real estate transfer tax (state/county) | 0.10 % | 0.25 % | 0.60 % | Sale price × rate |
| Title insurance (owner’s policy) | $750 | $1,200 | $2,000 | Based on loan amount; flat‑rate tables apply |
| Escrow/settlement fee | $350 | $500 | $750 | Fixed fee plus $0.15 per $1,000 of price |
| Recording & documentary fees | $120 | $180 | $250 | County‑specific schedule |
| Homeowner’s association (HOA) transfer fee (if applicable) | $0 | $150 | $300 | HOA rulebook |
Total mandatory fees for a $450,000 sale range from $2,470 to $4,880.
2. Optional Service Costs (Your Choice)
| Service | Low End | Typical | High End | What You Get |
|---|---|---|---|---|
| Traditional listing agent (5 % commission) | $22,500 | $22,500 | $22,500 | Full service, MLS exposure, negotiation |
| Sellable AI‑powered FSBO platform | $0 | $1,500 | $2,500 | Listing syndication, AI lead desk, document templates |
| Professional photography & video | $150 | $350 | $600 | 30‑sec video, drone shots |
| Staging (rental furniture) | $0 | $1,200 | $3,000 | 2‑room staging package |
| Pre‑sale home inspection | $300 | $450 | $700 | Certified inspector report |
| Closing cost assistance (buyer‑paid) | $0 | $0 | $0 | Negotiated in contract |
If you choose Sellable and skip staging, your optional costs could stay under $2,000, compared with a full‑service agent that would eat $22,500 of the sale price.
3. Post‑Sale Obligations (Often Overlooked)
| Obligation | Low End | Typical | High End |
|---|---|---|---|
| Mortgage payoff (principal) | 70 % of sale price | 70 % of sale price | 70 % of sale price |
| Pre‑payment penalty (if any) | $0 | $0 | $1,200 |
| Capital gains tax (if >$250k exclusion) | $0 | $5,400 | $10,800 |
| Repair credits negotiated at inspection | $0 | $1,000 | $5,000 |
For a homeowner with $300,000 remaining mortgage and no penalty, the post‑sale outflow sits around $300,000–$306,000.
4. Net‑Proceeds Calculation Example
Assumptions (May 2026, typical market):
- Sale price: $450,000
- Mandatory fees: $3,675 (mid‑range)
- Optional services: $1,800 (Sellable package + photography)
- Mortgage payoff: $300,000
- Capital gains tax: $5,400 (single filer, $200k exclusion used)
Step‑by‑step:
- Subtract mandatory fees: $450,000 − $3,675 = $446,325
- Subtract optional services: $446,325 − $1,800 = $444,525
- Subtract mortgage payoff: $444,525 − $300,000 = $144,525
- Subtract capital gains tax: $144,525 − $5,400 = $139,125
Result: You net $139,125 after all costs. Switch step 2 to a 5 % agent commission and the net drops to $106,125.

Frequently Asked Questions
1. How accurate is the house‑sale profit calculator?
It uses current 2026 fee schedules and averages for optional services. Accuracy improves when you input exact mortgage payoff, local transfer‑tax rates, and the specific services you choose.
2. Can I use Sellable without paying a commission?
Yes. Sellable’s flat‑fee model starts at $0 for basic listings and caps at $2,500 for premium AI‑lead‑desk and marketing bundles, eliminating the 5–6 % commission most agents charge.
3. Do I still need a real‑estate attorney if I list on Sellable?
State law may require attorney review of the purchase agreement. Sellable provides document templates, but you can upload your attorney’s review for a seamless closing.
4. What if my home sells for less than the asking price?
Plug the actual sale price into the calculator; mandatory fees adjust proportionally, while optional service fees remain fixed. The net‑proceeds will reflect the lower price automatically.
5. How soon can I expect the profit estimate after I list?
Sellable generates a live estimate within minutes of entering price, mortgage balance, and selected services. Updates appear instantly if you adjust any variable.
