Business calculator
Editor
Enter the total cost, total value returned, optional gains or fees, and the holding period in one practical layout. The ROI, annualized ROI, and breakdown update instantly as you compare business or personal scenarios.
The calculator keeps the core ROI values visible up front, adds simple adjustments for extra gains and fees, and includes a holding period so annualized ROI stays easy to compare.
Investment values
Start with the amount invested or spent, then enter the total value returned from the project, purchase, campaign, or investment.
Additional adjustments
Add extra income or extra costs if the scenario includes bonuses, side revenue, platform fees, commissions, or other project-specific adjustments.
Simple ROI is a profitability measure based on gain relative to cost. These extra gains and costs make the estimate more realistic without turning the calculator into a complex multi-cash-flow model.
Time period
Add the holding period so the calculator can translate the total return into annualized ROI for easier apples-to-apples comparisons.
Annualized ROI helps compare outcomes across different holding periods, but it is still an estimate from the values entered. Simple ROI does not account for risk, timing volatility, or uneven cash flows.

How it works
An ROI calculator estimates how profitable something was relative to its cost. A return on investment calculator helps turn a simple question, such as whether a campaign, project, or purchase paid off, into a clearer dollar-and-percentage answer.
Simple ROI starts with net profit or loss, which is total return amount minus total investment cost. The calculator then divides that net result by total investment cost to show ROI as a percentage. Positive ROI means the return exceeded the cost.
Net profit or loss is the plain dollar difference between what you got back and what you put in. This is often the easiest starting point because it answers whether the outcome added money or lost money before you think about percentages.
Additional gains can improve the outcome, while extra costs and fees raise the true cost base. Leaving them out can make ROI look better than reality, which is why this calculator lets you include both without overcomplicating the workflow.
A 20% gain over six months is not the same as a 20% gain over four years. Annualized ROI translates the overall result into a time-adjusted return measure, which makes it easier to compare opportunities with different holding periods.
Simple ROI is useful for quick analysis, but it does not account for risk, uneven cash flows, or more advanced investment modeling. Use these results as estimates based on the values entered, not as a replacement for IRR, DCF, or deeper financial analysis.
