How to use this calculator
- Enter annual avoided loss.
- Add annual control cost and implementation cost.
- Select Calculate and review the main estimate.
- Change one assumption to compare scenarios.
Use this ransomware control roi calculator to turn a small set of operating assumptions into a transparent planning estimate. Enter annual avoided loss, annual control cost, implementation cost, then review the primary result and two supporting figures. The page shows the exact formula, a worked example, and practical interpretation notes so you can compare scenarios without treating the output as a guarantee.
ROI = (avoided loss − annual control cost − implementation cost) ÷ (annual control cost + implementation cost) × 100
The three displayed input units are applied exactly as labeled; percentages are converted to decimals inside the calculation.
The primary figure is the calculated first-year roi. The supporting values separate important components so the result is easier to audit and compare.
This planning estimate depends on the accuracy of your inputs and does not replace a detailed operational, financial, or security assessment.
Using annual avoided loss = 60000, annual control cost = 18000, and implementation cost = 12000, substitute the values into the displayed formula. The calculator applies the same arithmetic and formatting used by the live result.
The result responds directly to annual avoided loss, annual control cost, and implementation cost as shown in the formula.
Zero is accepted where mathematically valid, but denominator inputs must be greater than zero to prevent an undefined result.
The calculation uses the values entered and cannot capture every operational, market, or behavioral factor.
Update the inputs whenever the underlying period, costs, volume, or operating assumptions change.
Yes. Record the first result, change one assumption at a time, and compare the recalculated output.
