Is this approach good?
To calculate revenue generated from computer hardware business in the UK last year, I would split into personal and business.
- Split population into age groups
- Find proportion of that age group that would own computer hardware
- Use replacement rate to find computer hardware that year
- Times by average price of laptop?
I'm not sure how to calculate business. My guess is that I would need to take into account peripherals and services but how would one start this?
