How it is calculated
Net gain = estimated effect of training − training cost. Training ROI = net gain ÷ training cost × 100% — by how many percent the effect exceeded the investment.
The hard part of this calculation isn't the formula — it's estimating the effect itself: unlike an ad campaign's ROI, where revenue is often directly measurable, training's effect usually has to be estimated indirectly, through productivity gains, fewer errors or defects, or faster task completion.
The more conservatively and defensibly the effect is estimated, the more useful the result: an inflated estimate produces a good-looking but untrustworthy ROI. It's worth recording exactly how the effect was calculated, so the result can be revisited against reality later rather than trusted only at the outset.
