I want to ask a question about the required revenue increase that we've calculated here as 6.67% for this question.
I understand that the total costs for closing commission and trailing commission are 5% each (as a percentage of the OPM).
We then calculated that if costs are increasing at a rate of:
5%/3 (due to trailing costs being over a 3 year period totalling 5%) + 5% (fixed closing commission) = 6.67%
that the revenue also must go up by 6.67% to cover the rise in operating costs.
How is this revenue increase also the same as the increase in the costs?
If you look at the formula, OPM is calculated as (gross profit - op. cost) / total revenue, so to calculate the total percentage change in the numerator, I'd need the raw gross profit figure first to figure the decrease change in the numerator and then know how much the denominator (i.e. the total revenue) needs to increase by to cancel the change.
Appreciate any feedback or corrections in advance!
