Course Investment FAQ
Everything you need to know about calculating the financial return of your professional development and upskilling.
The Return on Investment (ROI) of an evening class measures the financial gain you make from the course compared to its cost. It is calculated by subtracting the course cost from the expected salary increase, divided by the course cost, expressed as a percentage. A high ROI indicates the course pays for itself quickly and generates significant long-term value.
To calculate the payback period, divide the total cost of the course by the expected annual salary increase, and then multiply by 12 to get the number of months. For example, a £1,000 course that leads to a £5,000 salary increase has a payback period of just 2.4 months ((1000 ÷ 5000) × 12).

Yes, if the course is related to your current employment or trade, you may be able to claim tax relief on the course fees through HMRC. The training must maintain or improve skills required in your current job, rather than prepare you for an entirely new career path.
