Down Payment Calculator
Estimate upfront cash, explore a home price based on your cash budget, or find how much you can put down after closing costs.

Illustrative percentages, not loan eligibility requirements. Closing costs and the selected interest rate stay the same.

Monthly estimates exclude property taxes, insurance, mortgage insurance, HOA fees and other housing expenses. Cash targets exclude items you have not included in closing costs.
Understanding your upfront cash target
The down payment is the part of the purchase price paid from your own funds. In this model, the remaining price becomes the loan amount. Closing costs are separate cash expenses, while the reserve is money you keep after purchasing.
For a home priced at 300,000 with 20% down, the down payment is 60,000. If closing costs are 9,000 and you retain 5,000, your total savings target is 74,000. Of that amount, 69,000 goes toward the purchase and 5,000 remains in reserve.
Calculate from available cash
When closing costs are a percentage of the home price, modeled price = (available cash − reserve) ÷ (down-payment rate + closing-cost rate). With fixed closing costs, subtract those costs before dividing by the down-payment rate. If neither rate depends on price, cash alone cannot determine a unique price.
Is the calculated home price affordable?
The result only shows what your upfront cash could cover under your assumptions. It does not assess income, debt, credit, loan limits, lender approval or the ongoing cost of ownership.
How does the down-payment-from-cash mode work?
It subtracts closing costs and your reserve from available cash, then applies the remainder to the down payment, capped at the home price. Any cash beyond a full cash purchase is shown separately.
How is the monthly payment estimated?
The model uses a fixed nominal annual rate divided by 12 and equal monthly payments over the term. At zero interest, the loan is divided by the number of payments. A fully cash-funded purchase has no loan payment. Fees are not financed.
How long will saving take?
The savings gap is the cash target minus current savings, floored at zero. The calculator divides that gap by your monthly contribution and rounds up to whole months. The target includes your chosen reserve.
Does a larger down payment always make sense?
A larger down payment reduces the modeled loan and its payment, but leaves less cash available for other needs. This comparison holds rates and costs constant and does not model changes in mortgage insurance or loan terms.
