ROI is the universal yardstick
Every business decision has a return on investment. Marketing spend, equipment, new hires and software subscriptions all come down to the same question: does the return justify the cost? Track ROI on every meaningful expense and the weak ones get cut early.
How ROI is calculated
ROI is net profit divided by the amount invested, times 100. Net profit is the amount returned minus the amount invested. The multiple shows how many dollars came back for each dollar put in. If you add a time period, the calculator also shows the annualized return so you can compare investments of different lengths.
Frequently asked questions
Why does the time period matter?
To compare ROIs fairly, put them on a yearly basis. A 50% return in three months is very different from 50% over three years.
What should count as the investment?
Include every cost tied to the decision: purchase price, setup, staff time and ongoing fees. Leaving costs out makes ROI look better than it is.
