How this calculator works
Closing costs are the collection of fees and prepaid items due when you finalize your mortgage, separate from your down payment. Rather than a single number, they're a sum of many line items β some priced as apercentage of your loan amount (like origination fees and title insurance), and others asflat fees that don't scale with loan size (like the appraisal or credit report fee). This calculator sums each item's typical low-high range across the whole set:
Total closing costs = Σ (percentage items × loan amount) + Σ (flat-fee items)
The result is presented as a range rather than a single figure, because the true cost of each item genuinely varies β by state, by lender, and by which title/settlement company you use.
Worked example
For a $300,000 loan amount, this calculator's default line items sum to an estimated$6,180 at the low end and $14,500 at the high end β or roughly2.06% to 4.83% of the loan amount, squarely inside the commonly cited 2%-5% national range. The single largest variable items are typically prepaid interest & escrow, title search & insurance, and the loan origination fee, since all three are priced as a percentage of the loan and therefore scale directly with how much you borrow.
What affects your result
- Loan amount β the biggest driver, since several of the largest fees are priced as a percentage of your loan.
- State and county β title insurance rates, transfer taxes, and recording fees are all set locally and vary widely.
- Lender and title company β origination fees and settlement/attorney fees vary by provider; it pays to compare Loan Estimates.
- Time of year and escrow setup β prepaid interest and the initial escrow deposit depend on your closing date and how much cushion your escrow account requires.
A note on accuracy
This is a national planning estimate only, built from typical cost ranges cited in CFPB consumer guidance and Fannie Mae/Freddie Mac homebuyer education materials. It is not a quote and does not reflect your specific state, lender, or title company. Once you're under contract, your lender is legally required to provide an itemized Loan Estimate and, later, a Closing Disclosure with your actual costs β always rely on those official documents for your real numbers.
