How to Calculate Your Closing Costs
Follow one simple sequence to estimate your loan costs and cash to close.

Direct answer
There is no single formula. Costs depend on your loan, property, and closing date. Still, you can follow steps: start with your price range, list loan costs, add other costs and prepaids, subtract credits, keep your down payment separate, then check the lender's cash-to-close number.
A Step-by-Step Way to Estimate Your Range
Washington buyers often plan for two to three percent of the purchase price in closing costs. On a three-hundred-thousand-dollar price, that range is about six thousand to nine thousand dollars. On a four-hundred-thousand-dollar price, it is about eight thousand to twelve thousand dollars. These are planning figures, not quotes.
Buyers generally do not pay Washington's real estate excise tax. The state says the seller usually pays it. If the seller does not, the buyer becomes responsible. Check your contract to confirm.
What the Estimate Includes
Loan and title charges
These may include lender fees, appraisal fees, and lender's title insurance. Origination charges can cover application, underwriting, processing, and rate-lock fees. Some services can be shopped. The Loan Estimate tells you which ones.
Prepaid and reserve items
Lenders often collect prepaid interest and several months of homeowners insurance at closing. You may also see tax or insurance reserves.
Escrow and recording fees
Escrow or settlement charges cover the closing process itself. Recording fees pay the county to file your deed and loan papers. Both are separate from your down payment and loan charges.
What Changes the Final Number
Totals vary by loan type, property, address, lender, provider, closing date, credits, and contract terms. Two buyers on similar homes can see different totals. Lender credits can lower your closing costs, but they may come with a higher rate. Always compare the tradeoff.
Calculate Your Cash to Close
Cash to close is broader than closing costs. It adds your down payment plus closing costs, then subtracts deposits, seller credits, and other adjustments. Keep your down payment and closing costs as separate lines while you work, then combine them at the end.

Questions
Clear answers first. If one question changes the deal, bring it into the review before you move money.
Q1What is the difference between closing costs and cash to close?+
Closing costs are upfront fees for the loan and the transfer of ownership. Cash to close is broader. It adds your down payment and subtracts deposits, seller credits, and other adjustments already applied.
Q2Do I include my down payment when calculating closing costs?+
No. Keep them separate while you work. Your down payment and your closing costs are different line items. They combine only at the final cash-to-close step.
Q3How do I know which fees I can shop for?+
Your Loan Estimate shows which services you can shop for, such as certain title or settlement services. Fees the lender requires without options are listed separately.
Q4What does the Loan Estimate show me?+
It shows origination charges, prepaid items like insurance and interest, and other closing costs. It also flags which services you can shop for and estimates your cash to close.
Q5Why might my final costs differ from my early estimate?+
Totals vary by loan type, property, lender, provider, closing date, and any credits or contract changes. Your Closing Disclosure, given three business days before closing, has the verified numbers to compare.
