How the down payment calculator works

Cash needed = home price × down-payment percentage + estimated closing costs + protected reserve. Affordable price = cash after reserve ÷ (down-payment percentage + closing-cost percentage).

Cash to close excludes the emergency reserve. The reserve stays separate so the result does not assume every available dollar is spent at closing.

How to use this calculator

  1. Choose whether to solve for cash needed, supported home price, or down-payment percentage.
  2. Enter closing costs and the emergency cash you want to protect.
  3. Review down payment, cash to close, reserve, loan amount, and estimated principal-and-interest payment.

Worked example

Example: 20% down on a $400,000 home

A 20% down payment is $80,000. At 3%, estimated closing costs are $12,000.

Cash to close is about $92,000. Keeping a separate $10,000 emergency reserve means having about $102,000 available.

Frequently asked questions

Does cash to close include the emergency reserve?

No. Cash to close combines the down payment and estimated closing costs. The reserve is shown separately and remains protected.

Are closing costs always 2% to 5%?

That range is a common planning reference, but actual costs depend on the loan, location, services, credits, prepaid items, and transaction.

Does putting less than 20% down always require PMI?

No. Mortgage-insurance rules and products vary. The calculator flags the percentage so you can ask lenders what applies.
