Down Payment Calculator

Worked example

Example 1: $450,000 home at 20% down → $90,000 down before closing costs. Example 2: same home at 3.5% FHA-style down → much lower cash down but PMI/MIP and loan size rise.

When to use this

• Planning savings for a home purchase.
• Comparing 5%, 10%, and 20% down.
• Estimating cash with closing costs.
• Seeing loan size changes with price.
• Discussing options with a lender.

Common examples

• $450,000 home at 20% down → $90,000 before closing costs.
• 3.5% down scenario—lower cash, larger loan.
• 10% down plus estimated closing costs for cash-to-close.
• Toggle percent vs dollars to match savings.
• Price increase with fixed cash down → lower percent equity.

Common mistakes

• Forgetting closing costs in cash needed.
• Assuming 20% is always required.
• Ignoring gift funds rules.
• Using list price after credits incorrectly.
• Treating estimate as underwriting approval.

How it works

Converts between home price, down payment percent, and cash needed. Optionally layers estimated closing costs so you can see total cash to close.

Limitations

Formula or method

Down payment = price × percent. Loan amount = price − down payment. Cash to close ≈ down payment + closing costs − credits.
