Quick answer
Closing costs = price × percentage + sum of fixed fees. On a $300,000 purchase with 2.5% percentage-based costs and fixed fees of $1,200, $450 and $300, the estimate is $7,500 + $1,950 = $9,450.
Enter the purchase price, the percentage-based costs and fixed fees. The calculator returns the total and its parts.

The first line is the headline result (estimated closing costs). Below it the closing Costs Estimate Calculator lists percentage-based costs and fixed fees, which describe the same case from other angles. IEEE-754 double precision; shown to the decimals indicated.
Typical items
Percentage-based items include loan origination, title insurance and transfer taxes. Fixed items include appraisal, inspection, recording and attorney fees. Buyers commonly pay 2 to 5% of the price in total.
Rates are your input
Rates and fees are not built in; ask your lender for the Loan Estimate, which lists closing costs. They vary by state, loan type and lender.
How the result changes with purchase price
Holding every other input at the first worked example, this table changes only purchase price. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Purchase price | Estimated closing costs | Percentage-based costs | Fixed fees |
|---|---|---|---|
| 150000 | $5,700.00 | $3,750.00 | $1,950.00 |
| 300000 | $9,450.00 | $7,500.00 | $1,950.00 |
| 600000 | $16,950.00 | $15,000.00 | $1,950.00 |
| 1200000 | $31,950.00 | $30,000.00 | $1,950.00 |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Purchase price: entering "0" shows "Purchase price must be greater than 0." beside that field and no result.
- Fixed fees ($): entering "x" shows "“x” is not a number." beside that field and no result.

Background: rental property metrics
Rental property metrics answer different questions. The cap rate is net operating income divided by the purchase price and ignores financing; cash flow is income minus operating expenses minus debt service; cash-on-cash return divides annual cash flow by the cash you actually invested. Rules of thumb such as the 1% rule (monthly rent at least 1% of the price) are quick screens, not decisions.
Check the assumptions behind any result: vacancy, management fees, repairs and taxes. Published benchmark ranges for a good cap rate or return vary between sources.
Assumptions and limitations
- Rates and fees are not built in
Estimates only. Taxes, fees and lender or authority rules vary by place and date, so confirm figures with the relevant authority or professional.
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for purchase price and fixed fees ($) to confirm this.
