Retirement Return on Investment Calculator (20 Years)

Calculate return on investment as a percentage. This retirement version uses a 20-year planning term as its starting point.

The Return figure is the total gain or loss on the amount invested, expressed as a percentage of that amount, over the full 20-year term: a positive figure means the final value is above the amount invested, a negative figure means it is below it, and because it is a total rather than a yearly rate, the same percentage means a slower yearly pace when it is spread over a longer term.

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 20 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 percent. That is the calculator's own result for these defaults.

Spreading that 50.00 percent total evenly over 20 years gives a simple average of 2.50 percent a year. That average is an illustration only, not the output of this page: it is not compounded and it is not an annualised return. It is shown so the same total can be judged fairly over different terms.

Who this term suits for a retirement saver: a worker twenty years from retirement planning a long pot, such as a pension fund or a fund for later-life care, where a 50 percent total spread over twenty years is modest and must be compared with inflation over the same period.

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 retirement 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 50 percent over 20 years a realistic retirement return?
It is possible but slow, averaging 2.50 percent a year on a simple basis, so a twenty-year retirement plan should not rely on it alone without checking inflation, fees, and contributions along the way.

Why does the same investment look weaker over 20 years?
Because time dilutes the total. The $5,000 gain is fixed, so twenty years of waiting turns it into a small yearly pace, while the calculator still reports the same 50.00 percent total.

Should a 20-year retirement plan rely on one ROI figure?
No. A twenty-year plan also needs regular contributions, a check on risk as retirement nears, and a review of fees and taxes, since one total percentage hides all of those.
