Home Inflation Adjusted Value Calculator (15 Years)

Estimate what an amount will be worth after inflation. This home version uses a 15-year planning term as its starting point.

The Future amount is the larger sum needed after 15 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 15 years. Using the page formula, future amount equals $10,000 times 1.03 to the power of 15, which is $15,579.67. That is the calculator's own output for these defaults. The increase is $15,579.67 minus $10,000, which is $5,579.67, so a home cost priced at $10,000 today would need $15,579.67 in 15 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 $6,418.62 worth of today's goods after 15 years at 3 percent inflation, because $10,000 divided by 1.03 to the power of 15 is $6,418.62. After 15 years the money keeps barely two-thirds of its buying power.

Who this term suits for a home household: a home household planning to upsize in about 15 years, for example moving to a bigger home as children grow, where today's renovation or extension budget of $10,000 will cost about $15,579.67 by the time the move or the work actually happens.

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.

What does $15,579.67 mean for a 15-year home plan?
It means a home cost priced at $10,000 today should be budgeted at about $15,579.67 in 15 years if inflation runs at 3 percent a year, so a savings plan aimed at $10,000 will fall $5,579.67 short.

Should home income keep pace with inflation over 15 years?
It needs to, or the household falls behind. If pay rises more slowly than prices for 15 years, the same home costs take a bigger share of income, which is why long home plans should be reviewed whenever pay or prices change sharply.

Is a 15-year inflation figure reliable enough to plan on?
Only as a guide. Fifteen years is long enough for inflation to average well above or below 3 percent, so use $15,579.67 as a starting estimate and update it as real prices change, rather than treating it as a fixed future bill.
