How to use this down payment calculator

Use this down payment calculator to turn a target home price and percentage into a dated savings plan. It separates the down payment from closing costs and reserves so you can avoid committing every available dollar to the purchase.

  1. 1

    Set the home-price and percentage target

    Choose a planning price and down-payment percentage consistent with the loan options you are considering.

  2. 2

    Enter savings and time available

    Use funds specifically available for the down payment and the number of months before purchase.

  3. 3

    Review the monthly savings gap

    Compare the required contribution with your current budget and revise price, timing, or percentage as needed.

Worked planning example

Example: build a 20% down payment over three years

Set up

Enter the target home price, a 20% goal, current dedicated savings, and 36 months to buy.

Compare

Compare the monthly requirement with a smaller eligible down payment and a later purchase date.

Takeaway

Timing and target percentage can be adjusted, but closing costs and post-purchase reserves still need separate funding.

Protect cash beyond the down payment

A larger down payment can reduce borrowing, but using all liquidity can leave the household exposed after closing.

  • Create separate goals for closing costs and moving expenses.
  • Maintain emergency reserves after the purchase.
  • Confirm mortgage-insurance and program trade-offs for smaller down payments.

Calculation methodology and assumptions

For this down payment estimate, Silvia uses target home price, target down payment, current down payment savings, time to save, estimated savings return. Compare a target down payment with your current savings and estimate the monthly amount needed to close the gap. Results are estimates, not quotes, tax advice, or investment recommendations.

Frequently asked questions

How much down payment do I need?

Requirements vary by loan program, occupancy, lender, property, and borrower profile. The target is a planning choice, not an eligibility decision.

Does this include investment growth on savings?

No. It divides the remaining target gap over the entered timeline without assuming a return.

Are closing costs part of the down payment?

No. Closing costs, prepaid items, moving expenses, and reserves should be budgeted separately.
