The Formula

The down payment represents the initial equity contributed directly by the buyer at closing, with the remaining balance financed through a mortgage lender.

Down Payment Amount = Home Purchase Price × (Down Payment Percentage ÷ 100) Mortgage Loan Amount = Home Purchase Price - Down Payment Amount Savings Gap = Maximum(0, Down Payment Amount - Current Savings) Months to Goal = Ceil(Savings Gap ÷ Monthly Savings Contribution)

Where:

Example: Saving for a $350,000 Home

Suppose you are shopping for a home priced at $350,000. You currently have $15,000 saved and can comfortably contribute $1,000/month toward your down payment fund.

Frequently Asked Questions

Do I really need 20% down to buy a house?

No. While putting 20% down eliminates Private Mortgage Insurance (PMI) and lowers your monthly payment, qualified buyers can purchase homes with as little as 3% down on conventional loans, 3.5% on FHA loans, and 0% down on VA or USDA loans.

What is PMI and how much does it cost?

Private Mortgage Insurance protects the lender against loss if a borrower defaults. It is required on conventional mortgages when the down payment is under 20%. PMI typically costs between 0.4% and 1.5% of the loan amount annually, which equates to roughly $100 to $250 per month on an average home loan.

Does my down payment include closing costs?

No. Your down payment goes entirely toward paying for the property itself. Closing costs are separate lender, title, escrow, and government recording fees that generally total 2% to 5% of your purchase price and must be paid in addition to your down payment.

Where should I keep my down payment savings?

If you plan to buy within 1 to 5 years, keep your funds in a high-yield savings account (HYSA), money market fund, or short-term Certificates of Deposit (CDs). These accounts provide liquid, guaranteed returns without subjecting your down payment to stock market swings.

Can I use gift funds for my down payment?

Yes. Conventional and FHA guidelines allow buyers to use gift money from immediate family members to cover all or part of their down payment, provided the donor signs a formal gift letter confirming the funds do not require repayment.
