Shop Return on Investment Calculator (25 Years)

Calculate return on investment as a percentage. This shop version uses a 25-year planning term as its starting point.

This Return is the total gain over the whole period as a percentage of the amount invested, not a yearly rate; a positive figure means the final value is higher than the amount invested.

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 25 years. First, the gain is $15,000 minus $10,000, which is $5,000. Using the page formula, return equals $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: only the invested amount and the final value decide the answer.

As an illustration only, not the output of this page, the steady yearly rate that would grow $10,000 to $15,000 over 25 years, if growth were perfectly even every year, is 1.64% a year. The simple average, 50.00% divided by 25, is 2.00% a year, which ignores compounding and overstates the steady rate. The illustration is there so the same 50.00% total can be judged honestly over different lengths of time.

Who this term suits for a shop owner: a family shop thinking about the next generation, such as handing the business to a son or daughter, and asking whether a quarter-century of money tied up in the shop has actually grown.

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 shop 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.

Does 50% over 25 years beat rising shop costs?
Not necessarily. A 50% total gain over 25 years is a steady yearly illustration of only 1.64%, so if shop prices, rent, and wages rose faster than that on average, the real gain is smaller than the headline suggests.

How often should a 25-year shop ROI be recalculated?
Whenever the figures change in real life: a refit, a premises move, a big equipment purchase, or a change in takings. A 25-year figure left untouched for years is a history lesson, not a plan.

What if the shop is sold part-way through 25 years?
Then the final value is what the sale actually brings, and the return should be recalculated on the real holding period, not on the full 25 years. The page gives the total return for whatever two figures you enter.
