Personal Compound Annual Growth Rate Calculator (10 Years)

Calculate compound annual growth over a period. This personal version uses a 10-year planning term as its starting point.

What this means: the CAGR is the single steady yearly rate that would turn the starting value into the ending value over 10 years, so it summarises the whole period as one average yearly pace rather than showing each separate 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 10 years. First, the growth ratio is $20,000 divided by $10,000, which is 2.00. Using the CAGR formula, the rate is 2.00 to the power of one over 10, minus one, which is 7.18% a year. Check it back: $10,000 times 1.0718 to the power of 10 is about $20,000. Total growth is $10,000, or 100% over 10 years, but the yearly rate is 7.18%, not 10%, because compounding does part of the work.

Who this term suits for a person: A 10-year term suits a person planning a medium goal, for example a child's education fund, a career savings target, or a first house deposit built over a decade. A 7.18% yearly rate is in the range many diversified investments have aimed for, but it is not guaranteed, and the path over 10 years will almost certainly have included flat and falling years.

FAQs

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

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.

Is doubling in 10 years at 7.18% a good result?
It is a solid result, not an exceptional one. Doubling in 10 years needs 7.18% a year compounded, which is above a typical savings account but below what a very strong decade can produce. Judge it against inflation and fees over the same 10 years, not against the headline rate alone.

Does a 7.18% CAGR mean I earned 7.18% every year?
No. CAGR smooths the whole 10 years into one steady rate. Actual years may have been 20% up, 10% down, and flat in turn, yet still average out to 7.18% compounded. That smoothing is useful for comparison, but it hides risk and timing.

What should I check before using a 10-year CAGR to choose an investment?
Check the yearly returns, any fees taken out, whether tax was paid along the way, and whether money was added or withdrawn during the 10 years. This calculator assumes a single starting value growing to a single ending value, with no contributions or withdrawals in between.
