Fractional Executive Net Earnings Estimator

The Virtual Assistant Billable Capacity Estimator estimates the client-service hours a virtual assistant can realistically sell across a year. It separates total working time from the hours consumed by scheduling, inbox management, invoicing, onboarding, marketing, and other nonbillable tasks that still support the business.

The output helps independent VAs decide how many retainer hours or hourly clients they can support without assuming every working hour is billable. It can also provide a practical capacity input for pricing, workload reviews, and decisions about adding clients or subcontracting work.

1. Enter the average billable rate
Use the average hourly equivalent you expect to realize across your fractional executive client work.

2. Estimate weekly billable hours
Enter paid client hours, not total time spent working on the business.

3. Set working weeks
Reduce the annual weeks for vacations, holidays, planned breaks, or expected gaps.

4. Add annual business expenses
Enter the operating costs you want this earnings scenario to cover.

5. Choose a reserve percentage
Enter your planning percentage for taxes, then review gross revenue, profit, reserve, and estimated take-home.

Gross revenue = Hourly rate × Billable hours per week × Working weeks Estimated profit = max(0, Gross revenue − Annual business expenses) Tax reserve = Estimated profit × (Reserve rate / 100) Estimated net earnings = Estimated profit − Tax reserve

The model assumes the entered rate is an average realized billable rate and that annual expenses apply to the same year.

What the result means

The main result is estimated annual earnings left after the modeled business expenses and user-selected tax reserve.

This is a cash-planning estimate and does not calculate an actual tax return, employee benefits, or personal living expenses.

Given: a $475 hourly equivalent, 17 billable hours per week, 43 working weeks, $38,000 annual business expenses, and a 31% reserve rate.

Calculation:
Gross revenue = $475 × 17 × 43 = $347,225.
Estimated profit = $347,225 − $38,000 = $309,225.
Tax reserve = $309,225 × 0.31 = $95,859.75.
Net earnings = $309,225 − $95,859.75 = $213,365.25.

Result: estimated annual net earnings of $213,365.25.

Interpretation: The scenario shows the cash earnings produced by the selected rate and limited weekly client load after modeled costs and reserve.

How should I convert a monthly retainer to an hourly equivalent?

Divide the retainer by the client hours you expect to reserve or deliver for that retainer. Use a consistent method across clients so the average rate remains meaningful.

Should board meetings or executive travel count as billable hours?

Include them when they are compensated under the engagement. If they are unpaid, they still consume capacity and may reduce the billable hours you can sustain elsewhere.

Does the estimate include employer-provided benefits I gave up?

No. If you want to compare fractional work with employment, evaluate health coverage, retirement contributions, paid leave, and other benefits separately.

Can a high rate still produce modest net earnings?

Yes. Limited billable capacity, significant business costs, or a larger reserve percentage can reduce annual take-home even at a high hourly equivalent.

Does this estimator account for equity compensation?

No. It models cash client revenue only. Equity or performance-linked compensation should be valued separately because outcomes and liquidity can be uncertain.
