Return on investment

22.81%

Net return as a percentage of what you invest. Zero means the training pays for itself exactly.

Net return: $13,000.00; Total benefit less total investment over the period.
Total investment: $57,000.00; Fees plus the wage cost of time spent training.
Wage cost of training time: $27,000.00; Often larger than the course fee, and often left out of the business case.
Time-saving benefit: $58,500.00; Hours freed, valued at the wage cost: only real if that time is redeployed.
Error-reduction benefit: $4,000.00; Your stated error cost reduced by the improvement you expect.
Turnover benefit: $7,500.00; Replacement costs avoided by keeping people who would otherwise have left.
Break-even weeks: 42.34; Weeks until the benefit covers the investment, at the rate modelled.

Your numbers

Staff to be trained

People who will complete the training.

Training cost per person ($)

Course fees, materials and assessment. Excluding wages while training.

Training hours per person

Time away from normal duties, including any assessment.

Hourly wage cost ($)

Average total hourly cost of the staff being trained, including on-costs.

Hours saved per person per week

Time the training is expected to free up through faster or better work. Be conservative. This is the figure most often overstated.

Annual cost of errors this training addresses ($)

Rework, waste, incidents or claims across the whole group before training.

Expected reduction in those errors (%)

Percentage improvement you can defend, not the best case.

Annual staff turnover (%)

Percentage of this group who leave each year.

Expected reduction in turnover (%)

Percentage improvement attributable to the training and the development it signals.

Cost to replace one person ($)

Recruitment, induction and lost productivity until the replacement is effective.

Weeks the benefit is counted over

How long you claim the benefit lasts. 52 is one year; claiming longer needs justification.

How this is worked out

Investment = staff × (cost per person + training hours × wage cost). Time benefit = staff × hours saved × weeks × wage cost. Error benefit = error cost × reduction% × (weeks ÷ 52). Turnover benefit = staff × turnover% × reduction% × replacement cost × (weeks ÷ 52). Return = total benefit − investment. ROI% = return ÷ investment × 100.

What it assumes

Saved hours are redeployed to useful work. An hour freed and not used is not a saving.
The improvements are attributable to the training rather than to other changes happening at the same time.
Benefits begin immediately after training and hold steady across the period.
Everyone trained stays long enough to deliver the benefit.

What it does NOT account for

Backfill or overtime to cover people while they train.
Any benefit beyond the period you entered.
Improvements that are real but hard to price: safety culture, morale, service quality.
The cost of NOT training, which is often the stronger argument and is not modelled here.
The time value of money. Benefits are not discounted.

What to do next

Halve your hours-saved figure and re-run. If the case still holds, it is a case you can defend.
Decide before the training how each benefit will be MEASURED, and take a baseline. An ROI nobody verifies afterwards persuades once and never again.
Separate the benefits that are genuinely attributable from those that would have happened anyway.
Present the investment figure including wage cost: leaving it out is the fastest way to lose credibility with a finance team.
