Personal Down Payment Amount Calculator (15 Years)

Calculate a down payment from price and percentage. This personal version uses a 15-year planning term as its starting point.

The Down payment figure is the cash amount paid upfront from the price and percentage entered, and the Loan needed figure is the remaining amount to borrow, so a larger down payment directly reduces the loan needed.

Formula

Down payment equals price times down payment percentage divided by 100.

How it works

A larger down payment usually means a smaller loan and lower monthly payments.

Worked example

Price $300,000, down payment 20 percent, term 15 years. First, the down payment is $300,000 times 20 divided by 100, which is $60,000. The loan needed is $300,000 minus $60,000, which is $240,000. That $60,000 does not depend on the term, because the page formula uses only price and percentage. Saving illustration only, not the output of this calculator: to save $60,000 in 15 years, with no interest counted, takes about $333.33 a month for 180 months. Fifteen years makes the monthly amount feel easy, which is also its danger, because a price that looks fixed today will almost certainly not be $300,000 in 15 years.

Who this term suits for a person: A 15-year term suits a younger saver starting early, for example someone in their twenties putting about $333.33 a month aside for a future home while their career and pay grow. The risk is comfort: the monthly amount feels small, so it is easy to forget that the house they will buy in 15 years will not cost $300,000, and the $60,000 target must grow with it.

FAQs

How much down payment do I need?
It depends on the lender and the purchase. A common planning figure is 20 percent, but requirements vary.

Is this personal calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

How do I keep a 15-year down-payment plan on track?
Review it every year in three steps: check the current price of the kind of home wanted, recalculate 20 percent of that price, and compare it with the fund saved so far. Saving about $333.33 a month for 180 months reaches $60,000 with no interest counted, but the target will have moved by then, so the monthly amount should rise with pay and prices. Keeping the fund in a separate account, away from everyday spending, makes the yearly check honest.

Why is the monthly saving only about $333.33 at 15 years, and what is the catch?
Because $60,000 divided by 180 months is about $333.33, and spreading the same total over more months always lowers the monthly amount. The catch is that the total is not really fixed: 15 years of house-price rises will push the $300,000 price and the $60,000 target higher, while the saver is still putting aside about $333.33 a month. A low monthly amount is only a win if the target is re-priced as prices move.

Can I use a 15-year plan for a smaller purchase instead of a house?
Yes, the same maths works for any purchase, because the down payment is still price times percentage divided by 100. For a $100,000 purchase at 20 percent, the down payment is $20,000, and saving that over 15 years takes about $111.11 a month with no interest counted. The year pages in this group are written around a house example, but the calculator itself accepts any price and percentage the saver enters.
