Down Payment Calculator

How this result is built

Set a down-payment percent and see the monthly savings that reach it on your timeline.

A down payment is a date as much as a percent. Twenty percent of a price is a pile of cash. This calculator turns the gap, after what you have already saved, into a monthly deposit that assumes your savings earn a yield along the way.

What the opening example is for

If current savings already compound to the target, the monthly deposit is zero. That is a useful answer, not a blank page.

The walkthrough below uses the numbers already sitting in Down Payment Calculator. Press Calculate and the headline should match this page. Then put your own figures in. The math does not run until you press the button, and Clear hides the result.

What each field is doing

The “Target home price” line on Down Payment Calculator starts at $400,000.00. A round example is useful for learning the page. It is a poor substitute for the number on your own paperwork, so replace it and run the form again.

Down Payment Calculator treats “Down payment” as its own entry, and the form opens with 20%. The other fields stay put while you change this one. That is the clean way to see what this line is doing inside the result.

Before you replace it, “Already saved” reads $25,000.00 on Down Payment Calculator. If the label is a rate, type the annual figure the contract uses. If it is money, type the amount that will actually move, not a rounded hope.

The remaining fields

Look at “Months to save” first if you are checking Down Payment Calculator: the filled value is 36. Leave that figure only when it matches the statement, the quote, or the plan you are testing. Press Calculate after the edit so the chart and the schedule move with it.

The “Savings yield” line on Down Payment Calculator starts at 4%. A round example is useful for learning the page. It is a poor substitute for the number on your own paperwork, so replace it and run the form again.

The opening result, line by line

Press Calculate on the opening form and Down payment target is $80,000.00. That is the number the rest of this section is talking about.

Already saved is $25,000.00 when you run the opening figures on Down Payment Calculator. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

On this opening pass, still to save is $55,000.00. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

Down Payment Calculator reports that monthly savings needed is $1,440.49. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

How those lines were produced

Months is 36 when you run the opening figures on Down Payment Calculator. That line is part of the same calculation as the headline. It is not a second balance you can spend on top of the result. Change one input and press Calculate if you want to see whether this line moves.

The monthly figure assumes the savings earn the rate you entered, compounded monthly.

A second pass changes only “Target home price”, from $400,000.00 to $440,000.00. Down payment target moves from $80,000.00 to $88,000.00. Nothing else on the form was edited, so the gap between those two results is the effect of that one field on Down Payment Calculator. If the gap is tiny, this page is not very sensitive to that entry. If the gap is large, get that entry from a document before you plan around the result.

What this page will not claim

Down Payment Calculator does not know your credit score, the county’s tax bill, or what an appraiser will say. Type the price, the loan, and the escrow you were quoted. Compare the payment with the loan estimate, and treat a small rounding difference as normal.

Down Payment Calculator stops at its own formula. When the next question is different, open Mortgage Calculator (Principal, interest, tax, insurance, PMI, and HOA in one payment.); House Affordability Calculator (A price that fits income and the debts you already have.); Savings Goal Calculator (The deposit that hits a dated goal.). Do not add those results to this one as if they were the same kind of dollar.

Check the result before you use it

Start on Down Payment Calculator by reading the labels, not the headline. The opening labels are Target home price ($400,000.00), Down payment (20%), Already saved ($25,000.00), Months to save (36), Savings yield (4%). If a label is not the fact you have, the result cannot turn into that fact later. The illustration on the form lands on $80,000.00. When you press Calculate and see that same figure, the button and this explanation are using one formula.

Change one field at a time. Write down the headline, edit a single line, and press Calculate again. A large jump means that line carries the result. A line that does not move is a line the formula ignores, which is a reason to confirm you opened the right page. Down Payment Calculator is built for one job: The monthly amount that closes the gap. The description on the page says the same thing in a sentence: Set a down-payment percent and see the monthly savings that reach it on your timeline.

When the paperwork disagrees

Then hold the headline next to a source outside the site. That source might be a loan estimate, an account statement, a pay stub, or the public limit named in the methodology. A few cents of difference on a long schedule is ordinary rounding. A different rate, a fee you never typed, or a tax the form does not ask for is not rounding. Correct the input. Do not average the page with the paperwork.

When the outside source still disagrees, Down Payment Calculator has reached the edge of what it will claim. It will not phone a lender, pull a county record, or apply a credit you left blank. Send the calculator name, every input, and the result you expected through the contact page if you think the formula itself is wrong. Until that is settled, read $80,000.00 as the output of the fields above and nothing else.
