Shop Return on Investment Calculator (35 Years)

Calculate return on investment as a percentage. This shop version uses a 35-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 35 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 35 years, if growth were perfectly even every year, is 1.17% a year. The simple average, 50.00% divided by 35, is 1.43% 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 shop owner planning retirement, such as selling the business, passing it on, or winding down, and looking back over about 35 years to see what the money put into the shop actually returned.

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.

Why does the total matter more than the yearly rate at 35 years?
Because the steady yearly illustration is only 1.17%, a number so small it hides the real story. The total is a $5,000 gain on $10,000, and over 35 years the question is whether that gain kept up with a lifetime of rising costs.

Who benefits from a 35-year shop return if the owner retires?
Whoever owns the final value at the end: the owner if they sell, or the family member who takes over. A return that only exists on paper, in stock or fittings nobody will buy, is not money in hand.

Is 35 years too long to judge from one ROI figure?
Yes, on its own. One percentage over 35 years hides recessions, rent rises, new competitors, and changing customers. Use it as a starting check, then look at the years in between.
