Formula
How the calculation works
The calculator first finds the monthly salary increase and multiplies it by twelve to get the extra income in one year.
It multiplies that annual gain by the number of years you expect to keep the higher salary, then subtracts the total course cost.
Dividing the net gain by the course cost and multiplying by one hundred gives the return as a percentage.
Common mistakes
- Counting only one year of higher salary, which understates the return for a skill you keep using for years.
- Leaving out indirect costs such as travel, books and lost earnings while studying, so the net gain looks larger than it is.
When to use it
- Use it before enrolling in a costly certification to see whether the promised salary rise justifies the fee.
- Use it to compare two courses when one costs more but is likely to raise your salary by a larger amount.
Worked example
A course costing 200000 raises monthly salary from 30000 to 45000 over 3 years: net gain 340000 taka and a return of 170 percent.
Common questions
What does the return percentage mean?
It shows the net gain as a share of what the course cost, so 170 percent means you gain 1.7 taka for every taka spent.
