Mortgage Down Payments: Loan-to-Value, PMI, and Loan Costs

Why the down payment matters

A down payment is the part of a home’s purchase price that is not financed by the mortgage. A larger down payment usually means a smaller loan and lower loan-to-value ratio, but it also uses more cash. The best balance depends on the borrower, program, reserves, and actual offer.

Loan-to-value ratio (LTV)

LTV compares the loan amount with the property value used by the lender. For a simple purchase example, if a home is valued at $300,000 and the mortgage amount is $270,000, the LTV is 90%. The remaining 10% of the price is the down payment in this simplified example.

Actual lender calculations can use appraised value, purchase price, subordinate financing, and program-specific definitions. Review the lender's figures rather than relying on a home-price-only calculation.

Read the CFPB explanation of LTV for how it can affect costs.

Mortgage insurance and down payment

Some mortgage structures require mortgage insurance or a guarantee fee. For many conventional loans, private mortgage insurance (PMI) may apply when the down payment is below a threshold set by the loan and investor rules. FHA loans use their own mortgage-insurance structure; VA and USDA programs work differently. Do not assume that one down-payment percentage creates the same result across all products.

Ask whether the insurance is monthly, upfront, financed into the loan, cancellable, or payable for a program-defined period. The CFPB explains when conventional PMI may be removed and why the rules matter.

Do not use every dollar for the down payment

Cash is also needed for closing costs, prepaid taxes and insurance, moving, immediate repairs, furnishings, and an emergency reserve. Putting more money down can reduce the mortgage balance, but leaving too little cash after closing can make homeownership fragile.

Consider the full cash-to-close figure and what funds will remain after settlement. The Down Payment Calculator lets you enter the closing-cost and reserve amounts you expect instead of treating the down payment as the only cash goal.

Compare the program, not just the percentage

Different programs have different down-payment, loan-to-value, mortgage-insurance, funding-fee, and eligibility rules. Some eligible VA and USDA borrowers may have options with no down payment, while FHA and conventional products have different requirements. That does not mean all applicants qualify, that the loan has no fees, or that no cash is needed at closing.

Check current details through HUD, VA, and USDA and compare the lender's Loan Estimate.

Simple down payment arithmetic

On a $300,000 purchase price, a 5% down payment equals $15,000; 10% equals $30,000; and 20% equals $60,000. These are multiplication examples only. They do not say that a particular loan program will accept or require those amounts, or that mortgage insurance will be removed at a given percentage.

Frequently Asked Questions

Do I always need 20% down?

No. Some loan programs allow lower down payments for eligible borrowers. But a lower amount can affect mortgage insurance, pricing, or other costs.

Does a larger down payment always mean a lower total cost?

It generally reduces the amount borrowed, but the effect on total cost depends on interest rate, fees, insurance, cash reserves, and how long you keep the loan.

Is the down payment the same as closing costs?

No. The down payment reduces the purchase price financed. Closing costs and prepaid items are separate cash requirements.

Where can I plan a savings goal?

Use the Home Buying Down Payment guide and Down Payment Calculator.
