Each example keeps the benefit, relevant fees and comparison together. Net ROI is the stated attributable benefit after fees, divided by those fees. Figures use GBP. Calculations do not model VAT or income-tax effects. Additional costs or different facts change the result. Past outcomes do not promise the same result in another matter.
Avoidable rework
An evidenced £45,000 external rework requirement fell to £20,000 following a £10,000 preparation engagement.
£15,000net benefit after preparation fees
The comparison includes both the remaining rework and the preparation engagement. It does not treat all avoided rework as net saving.
£20,000 rework + £10,000 preparation = £30,000 total. £45,000 − £30,000 = £15,000; 150% of the preparation fee.
The £45,000 is the evidenced comparison requirement. The calculation concerns the stated expenditure, not an assumed regulatory outcome or approval.
Pre-launch decision
A founder proposed £300,000 of launch expenditure. A defined regulatory scoping engagement cost £6,000.
2%scoping cost relative to the proposed launch budget
A defined decision checkpoint comes before a much larger spending decision. The £300,000 remains a budget under consideration.
£6,000 ÷ £300,000 × 100 = 2%.
The proposed expenditure is not an assumed saving. This ratio is not ROI and does not imply launch or regulatory approval.
Reporting preparation
Six annual submissions required 20 hours each, reduced to 12 through clearer documentation and responsibilities.
48 hoursannual staff capacity released
The released capacity is valued at £6,000 annually using the stated employment-cost assumption.
6 × (20 − 12) = 48 hours annually. 48 × an assumed £125 hourly employment cost = £6,000.
Project costs have not been deducted. Capacity value is not cash saving unless expenditure falls. No net ROI or regulatory outcome is claimed.
