How do you calculate closing costs for the seller?

Short answer

Seller closing costs = agent commissions (typically 5–6%) + transfer taxes + owner's title policy + prorated property taxes + any concessions. On a $400,000 sale, sellers typically net $370,000–$375,000 after $24,000–$30,000 of costs — before paying off the mortgage.

Seller net sheet: $400,000 sale

ItemAmountNote
Sale price$400,000—
Commissions (5.5%)−$22,000Negotiable; split between agents
Transfer tax (example 0.5%)−$2,0000% in TX, 2%+ in some cities
Owner's title + escrow−$1,800Where seller customarily pays
Prorated taxes + misc−$1,500Up to closing date
Net before mortgage payoff$372,700≈ 93% of price

How to read this table

Context

Build a net sheet before listing, not after an offer arrives. The two levers with real room: commission (everything is negotiable post-2024; discount brokerages list for 1–2% on the listing side) and concessions (cap them in the counteroffer). Don't forget prorations — if you've prepaid property taxes past the closing date, you get credited back at the table.

What moves this number

Financing terms

Rate, down payment and amortisation drive cash-on-cash return more than purchase price does. The same building can cash-flow or bleed depending on the loan.

True operating expense ratio

Management, insurance, tax, maintenance, vacancy and capital reserve typically consume 35–50% of gross rent. Models that skip reserves overstate returns badly.

Vacancy and turnover

One 45-day vacancy plus a turn can erase a year of thin cash flow. Underwrite 5–8% vacancy even in tight markets.

Local regulation

Rent rules, short-term rental caps and licensing requirements change the achievable revenue of an identical property between neighbouring cities.

Methodology

Example uses mid-range 2025–2026 figures: 5.5% total commission, 0.5% transfer tax, customary seller-paid title. Local norms can shift several of these lines to the buyer.

Frequently asked questions

How do you calculate closing costs for the seller?

Seller closing costs = agent commissions (typically 5–6%) + transfer taxes + owner's title policy + prorated property taxes + any concessions. On a $400,000 sale, sellers typically net $370,000–$375,000 after $24,000–$30,000 of costs — before paying off the mortgage.

Which option pays the most in the seller net sheet: $400,000 sale table?

Sale price, at $400,000 (—). That row represents the strongest case in this dataset, so use it as an upper bound rather than an expectation.

What is a realistic low-end figure?

Prorated taxes + misc at −$1,500 (Up to closing date). Plan your costs so the low end still works, then treat anything above it as upside.

Why do the numbers vary so much?

The spread between the highest and lowest row is about 267×. Financing terms and true operating expense ratio explain most of that gap — see the drivers section above for the full list.

Where do these numbers come from?

Example uses mid-range 2025–2026 figures: 5.5% total commission, 0.5% transfer tax, customary seller-paid title. Local norms can shift several of these lines to the buyer.

How can I estimate my own number instead of using a benchmark?

Use the Closing Costs Calculator on RevenueLab — it takes your own inputs and returns a figure specific to your setup, which is always more accurate than a published range.
