The Agency Cost Estimator combines payroll, contractor spending, software, occupancy, marketing, and other operating costs into one period estimate. It supports budgeting and pricing by showing the cost base that agency revenue must cover.
Use fully loaded labor costs where possible, including employer taxes and benefits, rather than salary alone. Keep all entries on the same monthly, quarterly, or annual basis. The result highlights people-related cost and its share of total cost, which is often a key driver in service businesses.
1. Select a consistent period
Convert every cost to the same monthly, quarterly, or annual basis.
2. Enter employee cost
Use payroll plus employer taxes, benefits, bonuses, and other employment burden.
3. Add flexible labor
Enter expected contractor and freelancer spending.
4. Complete overhead inputs
Include software, facilities, sales activity, and other operating costs.
5. Review the cost mix
Use the people share to understand sensitivity to staffing and utilization.
Total agency cost = Payroll and benefits + Contractors + Software + Facilities + Sales and marketing + Other costs
People-related cost equals payroll plus contractor cost. Non-people cost equals the remaining categories. The model is an operating estimate and does not separately calculate depreciation, financing, income tax, or owner distributions unless included in an input.
The result is the estimated amount the agency must fund or recover through revenue during the selected period.
Avoid mixing cash payments with accrual expenses unless that is intentional for the planning use case.
Given: Payroll $180,000; contractors $45,000; software $12,000; facilities $9,000; sales and marketing $18,000; other costs $11,000.
Calculation: People cost = $225,000. Non-people cost = $50,000. Total cost = $275,000. People share = $225,000 ÷ $275,000 × 100 = 81.82%.
Result: Estimated total cost is $275,000.
Yes. A fully loaded payroll estimate should include employer taxes and benefits in addition to wages.
Use contractors when the spending is labor-like. Use other operating costs for materials or third-party production that does not fit another category.
It is primarily a period budget. For one project, enter only costs attributable to that project and interpret overhead carefully.
Update them when staffing, software contracts, rent, or sales plans materially change.
Only if every cost is fixed. When variable costs rise with revenue, break-even revenue requires a contribution-margin calculation.
