How Much Down Payment Do You Really Need?

A larger down payment can reduce the loan amount and may lower borrowing costs, but using every dollar upfront can leave a buyer exposed to repairs, moving costs, and emergencies. The right down payment is a balance between monthly affordability and cash flexibility.

20% down is useful, but not always required

The 20% number matters because a conventional loan with less than 20% down often requires private mortgage insurance. But many buyers use loan programs or lender options with smaller down payments. Some conventional options may start lower, FHA loans may allow low down payments for eligible borrowers, and VA or USDA programs may work differently for qualified buyers.

Because requirements vary by loan program, lender, credit profile, property, and location, use 20% as a comparison point instead of treating it as the only path.

How the down payment changes the payment

A higher down payment reduces the amount borrowed. That usually lowers principal and interest, may reduce or remove mortgage insurance, and can improve the overall affordability picture. It can also affect the interest rate and loan costs a lender offers.

Use the Mortgage Calculator to compare 3%, 5%, 10%, and 20% down on the same home price. Watch the monthly payment, loan amount, and cash left after closing.

Do not forget cash after closing

The down payment is only one upfront cost. Buyers may also need closing costs, prepaid property taxes, homeowners insurance, moving expenses, utility setup, repairs, furniture, and an emergency cushion. A bigger down payment is less helpful if it drains the money needed to safely own the home.

A practical test: after the down payment and closing costs, would you still have enough cash for moving, near-term repairs, and several months of essential expenses?

When a smaller down payment may make sense

• You qualify for a loan program that keeps the full payment affordable.
• You would otherwise spend too long saving while home prices or rent keep changing.
• You need to preserve cash for repairs, a job transition, or emergency savings.
• The PMI cost is manageable compared with the benefit of buying sooner.

When waiting for a larger down payment may help

• You are close to a threshold that meaningfully improves pricing or reduces PMI.
• The current payment would strain the monthly budget.
• You do not yet have cash set aside for closing and early homeownership costs.
• You want more negotiating room and less payment pressure.
