Down payment planning guide
A down payment is the portion of a property price paid upfront. This calculator converts a percentage or amount into the estimated down payment, loan amount, LTV, and cash target for a home purchase.
How to use this calculator
Enter the property price, choose Percentage or Amount, and calculate the basic loan estimate. Open Advanced Options when you want to include closing costs, other purchase costs, savings, a reserve, a monthly savings pace, or a target date.
Calculation methodology
The down payment is the property price multiplied by the selected percentage, or the amount entered directly. The estimated loan amount is property price minus down payment, and LTV is estimated loan amount divided by property price. Estimated cash needed at closing adds the down payment, closing costs, and other upfront costs. The reserve is added to the savings target but is not spent at closing.
Key terms
- Down payment
- The part of the purchase price paid upfront rather than financed.
- Property price
- The target price used to estimate the down payment and amount that may need financing.
- Loan amount
- The estimated property price remaining after the down payment, before lender-specific adjustments.
- Loan-to-value ratio (LTV)
- The estimated loan amount as a percentage of the property price. It is not an approval decision.
- Closing costs
- Purchase fees and charges that are separate from the down payment and vary by transaction and location.
- Cash to close
- The estimated down payment plus closing costs and other upfront purchase costs.
- Mortgage insurance
- A possible loan-program cost that may apply when the down payment is below a stated threshold, often 20%, depending on the program.
- Emergency reserve
- Savings intentionally kept after purchase for emergencies and unexpected costs.
- Savings goal
- Estimated cash to close plus the reserve you want to keep.
- Target purchase date
- An optional date used to compare the target with a monthly savings pace.
Practical planning guide
Calculate the cash requirement, not just the percentage.
Add closing costs and other upfront costs separately so your cash-to-close estimate is more realistic.
Compare several down-payment percentages.
A larger down payment generally reduces the estimated loan amount and LTV, but it also uses more cash upfront.
Keep a separate emergency reserve.
Do not treat every dollar of savings as available for closing; moving, repairs, and emergencies still need funding.
Keep closing costs separate from the down payment.
Fees can vary by lender, location, taxes, services, and prepaid items, so use an estimate and verify it with the lender or settlement provider.
Use LTV as a planning measure.
LTV can affect loan pricing or mortgage-insurance requirements, but actual rules depend on the loan program and lender.
Check the savings pace against the target date.
If the target date requires more monthly savings than is comfortable, adjust the date, property price, or cash plan before making an offer.

Frequently asked questions
Is a larger down payment always better?
Not always. It can reduce the estimated loan amount and LTV, but using too much cash can leave too little for reserves, repairs, and other ownership costs.
Are closing costs included in the down payment?
No. This calculator keeps closing costs separate and adds them only to the estimated cash-needed-at-closing figure.
What does the LTV percentage mean?
It is the estimated loan amount divided by the property price. A higher LTV means more of the property price is financed.
Does the calculator determine mortgage approval?
No. It provides planning estimates only. Approval, pricing, mortgage insurance, and minimum down-payment rules depend on the lender, loan program, property, and borrower.
What are other upfront purchase costs?
They can include moving, setup, immediate repairs, or other costs you expect around the purchase. Enter only an amount you have a reason to estimate.
How is the emergency reserve treated?
The reserve is not counted as cash spent at closing. It is added to the total savings target so the plan aims to keep that amount after purchase.
Can I use a target purchase date?
Yes. With a target date and a savings shortfall, the calculator estimates the average monthly savings needed to reach the target by that date.
Does this calculate a mortgage payment?
No. It estimates the amount that may need financing. Use the Mortgage Calculator for a payment, interest, and amortization estimate.
