About the Down Payment Calculator

The Numelios Down Payment Calculator helps estimate the cash needed for a home down payment, the resulting mortgage amount, and the loan-to-value ratio based on the purchase price and down payment percentage.

It can be used to compare common down payment levels and understand how a larger or smaller down payment may affect the size of the mortgage.

How Down Payment Is Calculated

The down payment is calculated as a percentage of the home purchase price.

Down Payment = Home Price × Down Payment %

The remaining amount becomes the estimated mortgage principal.

Mortgage Amount = Home Price − Down Payment

Example

Suppose a home costs $400,000 and you make a 20% down payment.

Home Price $400,000
Down Payment $80,000
Mortgage Amount $320,000
LTV 80%

Common Down Payment Percentages

3% Down

Some mortgage programs allow relatively low down payments, though eligibility and mortgage insurance requirements may apply.

5% Down

A 5% down payment reduces the amount financed compared with minimum-down-payment options while still preserving more cash.

10% Down

A larger down payment can reduce the mortgage balance and potentially lower monthly housing costs.

20% Down

A 20% down payment results in an 80% loan-to-value ratio and may eliminate private mortgage insurance requirements on many conventional loans.

What Is Loan-to-Value Ratio?

Loan-to-value ratio, or LTV, compares the mortgage balance with the value or purchase price of the property.

LTV = Mortgage Amount ÷ Home Value × 100

A lower LTV generally means the borrower is financing a smaller percentage of the property's value.

Down Payment vs. Cash Needed at Closing

The down payment is only one part of the upfront cost of purchasing a home. Buyers may also need funds for lender fees, title charges, taxes, prepaid insurance, escrow deposits, and other closing expenses.

Use the Closing Cost Calculator to estimate additional cash that may be required at closing.

Frequently Asked Questions

Do I need 20% down to buy a home?

Not always. Some mortgage programs permit lower down payments. Requirements depend on the loan program, lender, borrower profile, and property.

What happens if I make a larger down payment?

A larger down payment reduces the amount borrowed and may lower the monthly mortgage payment and total interest paid.

What is PMI?

Private mortgage insurance may be required on certain conventional mortgages when the borrower finances a high percentage of the home's value.

Is the down payment included in closing costs?

The down payment and closing costs are separate components of the total cash needed to complete a home purchase.

Can a down payment affect the mortgage rate?

It can. Loan-to-value ratio is one of many factors that may influence mortgage pricing and qualification.
