# Calculation on a month to month basis (so, based on pro-rata sales figures) for a 12 mont

1. ## Calculation on a month to month basis (so, based on pro-rata sales figures) for a 12 mont

Hi there,

I am trying to do an IF function formula to say for each \$20,000,000 of annualized revenue (i.e. \$1,666,667 per month), we need to add variable staffing costs of \$300,000 per year (\$30,000 per month). So, for example, if we were doing \$100,000,000 of annualized revenue, we would need \$1,500,000 per year (or \$120,000 per month) of variable staffing costs....

I need this calculation on a month to month basis (so, based on pro-rata sales figures) for a 12 month budget.

Can anyone help with the formula?

Dean
