Investment Return on Investment Calculator (10 Years)

Calculate return on investment as a percentage. This investment version uses a 10-year planning term as its starting point.

The return result is the total percentage gain or loss on the amount invested over the whole term, so a positive percentage means the final value is higher than the amount invested, and it is not a yearly rate.

Formula

Return equals final value minus invested amount, divided by invested amount, times 100.

How it works

A positive return means the final value is higher than the amount invested.

Worked example

Amount invested $10,000, final value $15,000, term 10 years. Using the page formula, return equals $15,000 minus $10,000, divided by $10,000, times 100, which is $5,000 divided by $10,000, times 100, which is 50.00%. That is the calculator's own result for these defaults, and it is the same on every page in this group because the term is not an input.

That 50.00% is a total over the whole term, not a yearly rate. As illustrations only, not outputs of this page, the simple average is 50 divided by 10, which is 5.00% a year, and the steady rate that would compound $10,000 to $15,000 over 10 years is 4.14% a year. The same total gain looks much smaller when it is spread over twice as many years.

Who this term suits for an investor: an investor holding a medium-term position, for example a diversified fund, a rental property held for a decade, or a business investment left to mature, who wants to see whether a 50% total gain over 10 years kept pace with safer alternatives.

FAQs

What is a good ROI?
There is no single good figure. Compare returns over the same period and with the same risk before deciding.

Is this investment 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 the same 50% look smaller over 10 years than over 5 years?
Because the gain is spread over twice as many years. The steady compounded rate falls from 8.45% a year over 5 years to 4.14% a year over 10 years, even though the total gain is unchanged.

Is 10 years a fair horizon for judging one investment?
It is a reasonable horizon for most investments, long enough to smooth out single bad years, but still check whether fees, taxes, and inflation were counted, since this page does not include them.

Should a 10-year investor compare this return with inflation?
Yes. A 50% total gain over 10 years is only a real gain if it beats the rise in prices over the same period. Compare the 4.14% steady rate with average inflation before calling it a good result.
