10%
$120,000 of profit
The allocations total 90%, leaving 10% against a 12% target. Something has to come down by 2% of revenue: marketing and payroll are usually where the room is.
How the Business Budget Calculator works
Budgeting as percentages of revenue keeps costs proportional as the business grows, which fixed budgets do not. The allocations also have to leave the target net margin, if they total more than they should, something has to come down before the year starts.

Frequently asked questions
What percentage of revenue should each cost be?
It varies by model, but ecommerce commonly runs 40-55% cost of goods, 10-20% marketing, 10-20% payroll and 5-15% fulfilment. Your own history beats any benchmark.
Why budget as percentages?
Because most costs scale with revenue, so a percentage budget stays valid as the business grows. A fixed budget is wrong within a quarter in a growing business.
What if the percentages exceed 100 less my target?
Then the plan does not produce the target margin. Marketing and payroll are usually where the room is, and deciding that in advance is easier than discovering it in month eight.
Should the budget flex during the year?
Percentage budgets flex automatically with revenue. What should not flex is the target margin, that is the constraint the whole budget exists to protect.
