Home Compound Annual Growth Rate Calculator (25 Years)

Calculate compound annual growth over a period. This home version uses a 25-year planning term as its starting point.

The result labelled CAGR is the steady yearly growth rate that would take the starting value to the ending value if growth were perfectly even every year, so a CAGR of 2.81% over 25 years describes a smooth average pace, not a rise that happened by that amount in any single year.

Formula

CAGR equals ending value divided by starting value, to the power of one over years, minus one.

How it works

CAGR smooths growth into a single yearly rate, even if actual yearly growth varied.

Worked example

Starting value $10,000, ending value $20,000, term 25 years. Using the page formula, CAGR equals $20,000 divided by $10,000, to the power of one over 25, minus one, which is 2.81% a year. That is the calculator's own result for these defaults, and it is the steady yearly rate that would grow $10,000 to $20,000 over 25 years if growth were perfectly even every year.

Note that 2.81% is lower than the simple average of 4.00% a year, which just divides the 100% total gain by 25 years. The simple average ignores compounding, so it overstates the steady rate; the CAGR figure is the one that actually reproduces the doubling when compounded year after year.

Who this term suits for a home household: A home household measuring a generation-length holding, for example a family home bought in early working life and valued again about 25 years later, near retirement planning.

FAQs

What does CAGR mean?
CAGR is the steady yearly growth rate that would take a starting value to an ending value.

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 is the 25-year rate only 2.81% a year?
Because the same doubling is spread over 25 years of compounding, so a much smaller yearly rate is enough to turn $10,000 into $20,000.

Does 2.81% a year beat inflation over 25 years?
Only if inflation averaged less than 2.81% a year over that period; if prices rose faster, the home gained in nominal terms but lost buying power.

Is a 25-year home growth figure useful for selling decisions?
Only as background. A selling decision should use current local prices and costs, not a smoothed rate from a quarter of a century ago.
