Down Payment Calculator

The percent down is only part of the cash. Closing costs sit on top, and you can change that percent. This is not a lender's cash-to-close.

Written for Equidwell and last checked in October 2026. We build the calculators on this site. We are not a lender, and this page is not advice for your loan.

How this calculator works

  1. Each column uses the same home price, rate, taxes, and insurance.
  2. The down payment is 5%, 10%, 15%, or 20% of the price.
  3. PMI is estimated only when the loan is above 80% of the price.
  4. Cash required adds the closing-cost percent to the down payment.

A larger down payment buys a smaller loan

Going from 5% to 20% means more cash on closing day, a smaller loan, and, in this model, no PMI. The monthly payment usually falls for both reasons.

Read it as a cash-versus-payment comparison. It will not tell you to empty an emergency fund. Reserves are not in the columns.

Common questions

Is 20% required?

No. The 20% column is the point where this model stops estimating PMI. Many loan types allow less down, with their own mortgage-insurance rules.

Are closing costs the same in every state?

No. The percent here is an assumption you edit. It is not a state schedule.
