It estimates the one-time costs you pay at closing — lender fees, title charges, taxes, and prepaid escrow. These land on top of your down payment.
The Closing Cost Formula, Explained
Total closing costs ≈ lender fees + title + taxes + prepaids
Closing costs commonly run 2% to 5% of the purchase price. The mix shifts by loan type and price point. Title and government charges make up a large share in many transactions.
Prepaid items are not fees but money set aside in escrow — the first chunk of property taxes and insurance. The calculator separates true fees from prepaids so you can see where your money goes.
The formula is only the starting point. Open the closing cost calculator to plug in your own numbers and see the result instantly. For a rate tied to your actual file, talk to a licensed broker before you decide.
