How much cash do you really need to buy a home? Many buyers plan for the down payment and forget closing costs. The Down Payment Calculator adds both so you can see your true upfront cash need.
Enter the home price, your down payment percentage, and an estimated closing cost percentage. The tool returns the cash needed, the down payment, the closing costs, and the loan amount. It is built for first-time buyers and anyone comparing down payment plans.

What the Calculator Does
Three inputs produce four dollar results.
- Home Purchase Price ($): the price you expect to pay.
- Down Payment Percentage (%): your share paid up front.
- Estimated Closing Costs (%): fees as a percent of the price.
- Total Upfront Cash Required: the down payment plus closing costs.
- Down Payment Amount: the dollars for the down payment alone.
- Estimated Closing Costs: the closing cost percent turned into dollars.
- Financed Loan Amount: the price minus the down payment.
Press Calculate Cash Needed, or the Enter key, to refresh the cards. The page shows results for the starting values when it loads.
How to Use It, Step by Step
- Enter the expected price in Home Purchase Price ($), from $10,000 to $10,000,000,000.
- Type your target in Down Payment Percentage (%). The starting value is 20, and the allowed range is 0 to 100.
- Enter a closing cost estimate in Estimated Closing Costs (%). The starting value is 3, and the allowed range is 0 to 10.
- Press Calculate Cash Needed.
- Read the four cards. Change a percentage and press the button again to compare plans.
The Down Payment Formula
Closing costs and the down payment both come from the purchase price. The loan is what remains after the down payment.
Price × Down %+Price × Closing %=Total Cash Needed
- Down payment = price × (down payment % ÷ 100).
- Closing costs = price × (closing cost % ÷ 100).
- Total upfront cash = down payment + closing costs.
- Financed loan = price - down payment.
The closing cost gets its own card, so you do not need to subtract anything to find it.
Worked Example
Ana plans to buy a $425,000 home. She wants to put 10% down and expects closing costs of 3%.
| Result | Calculation | Output |
|---|
| Down Payment Amount | $425,000 × 0.10 | $42,500.00 |
| Estimated Closing Costs | $425,000 × 0.03 | $12,750.00 |
| Total Upfront Cash Required | $42,500 + $12,750 | $55,250.00 |
| Financed Loan Amount | $425,000 - $42,500 | $382,500.00 |
Ana needs $55,250 in the bank to close, and she would borrow $382,500.
How to Read the Results
Total Upfront Cash Required is the amount to have saved before closing day. Down Payment Amount is the part that goes toward the price. Estimated Closing Costs is the fee estimate in dollars, and it is already included in the total.
Financed Loan Amount is what you would borrow. It is the starting point for a monthly payment estimate.
Comparing Down Payment Plans
Here is the same $425,000 home with closing costs held at 3%. Only the down payment percentage changes.
| Down Payment | Down Payment Amount | Total Upfront Cash | Financed Loan |
|---|
| 3.5% | $14,875.00 | $27,625.00 | $410,125.00 |
| 10% | $42,500.00 | $55,250.00 | $382,500.00 |
| 20% | $85,000.00 | $97,750.00 | $340,000.00 |
A larger down payment cuts the loan but raises the cash you need on closing day.
What Else Shapes Your Cash Need
On a conventional loan, putting down less than 20% usually means paying private mortgage insurance. FHA loans allow as little as 3.5% down for qualified buyers. Ask your lender which rules apply to you.
This tool stops at the loan amount. To turn that loan into a monthly payment, use the mortgage calculator. The loan to value calculator shows how your down payment affects your loan-to-value ratio.
Closing fees vary a lot by lender and location. The closing cost calculator gives a fuller view of them. Check your price range with the house affordability calculator. Then size your rainy-day cushion with the emergency fund calculator. Taxes add to ownership costs, so see the property tax calculator too. Find more in the finance and business calculator hub.
Limitations and Assumptions
- Closing costs are a flat percent of the price, not of the loan.
- The tool does not include earnest money, moving costs, repairs, or cash reserves.
- It does not calculate interest, monthly payments, or mortgage insurance.
- The loan amount does not add closing costs, even if you plan to finance some.
- The tool enforces its limits: price $10,000 to $10,000,000,000, down payment 0% to 100%, and closing costs 0% to 10%.
- A blank or out-of-range field shows a red message, and every card reads N/A. A blank percent no longer counts as 0.
- Results update only when you press the button or the Enter key.
FAQs About the Down Payment Calculator
How much down payment do I need to buy a house?
It depends on the loan type and lender. Many buyers aim for 20% to avoid mortgage insurance, but some loans allow far less.
Are closing costs part of the down payment?
No. Closing costs are fees paid at closing, separate from the down payment. This tool adds them together so you see the full cash need.
What closing cost percentage should I enter?
Use an estimate from your lender, because fees vary by location and loan. The starting value of 3 is only an example.
Why is the financed loan amount not affected by closing costs?
The tool subtracts only the down payment from the price. If you roll closing costs into the loan, add them yourself.
Does this calculator show my monthly mortgage payment?
No. It shows cash needed up front and the loan amount. Use a mortgage calculator with your rate and term for the monthly payment.
Can I enter a dollar amount instead of a percentage?
No. The down payment field takes a percentage only. Divide your dollar amount by the price and multiply by 100 to convert it.
