Home Inflation Adjusted Value Calculator (10 Years)

Estimate what an amount will be worth after inflation. This home version uses a 10-year planning term as its starting point.

The Future amount is the larger sum needed after 10 years to buy the same things as the starting amount buys today, so it shows how much rising prices reduce the buying power of your money over time.

Formula

Future amount equals amount times one plus inflation rate to the power of years.

How it works

Inflation means the same amount buys less over time, so future prices are higher.

Worked example

Amount $10,000, inflation rate 3 percent, term 10 years. Using the page formula, future amount equals $10,000 times 1.03 to the power of 10, which is $13,439.16. That is the calculator's own output for these defaults. The increase is $13,439.16 minus $10,000, which is $3,439.16, so a home cost priced at $10,000 today would need $13,439.16 in 10 years to buy the same thing if inflation ran at 3 percent every year.

Looked at the other way, $10,000 kept aside without any return would buy only about $7,440.94 worth of today's goods after 10 years at 3 percent inflation, because $10,000 divided by 1.03 to the power of 10 is $7,440.94. Over a decade, more than a quarter of the money's buying power is gone, which is why a home deposit fund needs to grow, not just sit.

Who this term suits for a home household: a home household saving toward a first home deposit or a major home improvement fund over about 10 years, where the deposit target itself keeps moving upward with prices, so saving a fixed sum from today may still fall short when the time comes to buy.

FAQs

What does inflation do to money?
Inflation reduces what money can buy, so a sum today will need to be larger in future to buy the same things.

Is this home 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.

Why does a $10,000 home deposit need $13,439.16 after 10 years?
Because inflation compounds. Each year prices rise by 3 percent on the already higher price, so $10,000 times 1.03 to the power of 10 is $13,439.16, which is $3,439.16 more than the starting figure.

Is 10 years too long to trust one inflation rate?
It is long enough for the real rate to differ a lot from 3 percent, so treat $13,439.16 as a planning figure and revisit it every year or two, rather than fixing a 10-year savings plan once and never checking it.

What if inflation averages more than 3 percent over 10 years?
Then the future amount will be higher than $13,439.16. Entering a higher rate on the page shows the new figure at once, which is the safer way to test a home deposit plan before committing to it.
