What this calculator does
Estimate buyer and seller closing costs with transparent assumptions and a cash-to-close view.
How it's calculated
- Inputs are validated before running the calculator-specific compute() function.
- Core math is deterministic and implemented in src/lib/calculators/closing-costs.ts.
- Results are recalculated instantly as values change and are shareable via query parameters.
- Disclosure assumptions and limitations are shown on-page for decision context.
Example
Example scenario: Home price = 500000 USD; State baseline = National Average; Loan type = Conventional; Down payment input mode = USD amount. Sample output: Typical buyer closing costs: $12,243.49
Common mistakes
- Using optimistic rates or appreciation assumptions without testing a conservative case.
- Ignoring taxes, insurance, HOA, or maintenance in monthly cost planning.
- Treating modeled outputs as guaranteed quotes rather than planning estimates.
- Not comparing at least two scenarios before making a financing decision.
- Skipping professional review for legal, tax, underwriting, or insurance details.
FAQs
How much are buyer closing costs usually?
A common planning range is roughly 2% to 5% of purchase price, but local taxes, title fees, and lender charges can move this outside that range.
What is the difference between closing costs and cash to close?
Closing costs are transaction expenses. Cash to close is broader and typically includes your down payment plus closing costs and prepaids.
Are prepaids the same as fees?
No. Prepaids generally fund items like property taxes, homeowners insurance, and prepaid interest. They are upfront funding, not pure transaction fees.
Does this include buyer and seller estimates?
Yes. You can toggle seller costs on or off and model commissions, concessions, transfer taxes, and title/escrow share.
Why do state selections matter?
State defaults adjust transfer tax assumptions and government fee multipliers. Local county and city rules can still differ from this baseline.
What this calculator does
This calculator estimates buyer and seller closing costs with low, typical, and high ranges so you can plan before lender and title documents are finalized. It also separates closing costs from cash to close, which includes down payment and upfront funding.
What's included in closing costs
- Lender fees: origination, underwriting, appraisal, and processing-type fees.
- Title and escrow: title insurance, settlement, and closing handling.
- Recording and government fees, adjusted by state-level baseline multipliers.
- Transfer tax estimate when enabled.
- Prepaids for taxes, insurance, and interest timing.
- Optional points cost (points percent multiplied by loan amount).
What affects closing costs by state
Transfer tax practices, county recording structures, and settlement conventions vary by state and local jurisdiction. This page uses a lightweight state baseline model to nudge government fees and transfer-tax assumptions, but your county-level rules and negotiated credits can still move final numbers.

Example scenario
Example inputs: Home price $500,000, state baseline set to National Average, conventional loan, 20% down, 6.5% rate, no points, transfer tax on, and title/escrow on. Typical buyer closing costs may land around mid-single-digit thousands to low-five figures depending on tax and insurance assumptions. Cash to close is materially higher because it includes the down payment.

Common mistakes
- Budgeting only for down payment and ignoring closing costs and prepaids.
- Assuming transfer taxes are identical across every county and state.
- Treating prepaids as negotiable lender fees when they are often funding items.
- Ignoring points and credits when comparing lender offers.
- Using one exact estimate without testing low and high scenarios.
- Failing to verify final numbers against lender and title/escrow documents.
FAQs
What percentage of home price should I expect for buyer closing costs?
A practical planning range is often about 2% to 5% of purchase price, with meaningful local variation by taxes, title fees, lender structure, and credits.
Why does this calculator show a low, typical, and high estimate?
Final closing disclosures depend on lender, title company, state and county rules, and negotiated terms. Ranges are more realistic than one hard number early in planning.
Are prepaids part of closing costs?
Prepaids are often shown at closing but are conceptually different from fees. They usually fund upcoming property taxes, insurance, and interest timing.
Is cash to close the same as closing costs?
No. Cash to close typically includes down payment plus buyer closing costs and prepaids, so it is usually higher than closing costs alone.
Do seller costs always include both agent sides?
Not always. Commission structures are negotiated and can vary by market and agreement. This tool uses transparent defaults for planning only.
Can transfer taxes be zero?
Yes in some locations, while others have state, county, and city transfer taxes. Use the state baseline as a directional input, then verify local rules.
Should I include points in closing costs?
If you plan to buy points, include them. Points increase upfront costs and may reduce rate; whether they pay off depends on hold period and savings.
How do I get the final number?
Use this estimate for planning, then confirm with your lender Loan Estimate and title/escrow fee worksheet before final decisions.
