Task Marketplace Billable Capacity Estimator

This estimator turns a task marketplace worker’s weekly availability into billable capacity after accounting for proposal, messaging, travel, and other non-billable time. It then uses average task length to estimate how many tasks could fit into a week and a working year. The calculator is useful for revenue planning because income targets should be based on hours that can actually be sold, not the full number of hours you are willing to work. It can also help identify whether very short tasks create too much overhead relative to the time available. Capacity is a scheduling estimate only; marketplace demand, client response times, and task mix still determine how much of it is actually sold.

1. Enter weekly availability
Start with the total time you are willing to devote to marketplace work.

2. Remove non-billable overhead
Estimate the percentage consumed by applications, client messages, travel, scheduling, and other time you cannot charge.

3. Set working weeks
Account for vacations, holidays, or weeks you do not plan to accept marketplace work.

4. Estimate average task size
Enter the average number of billable hours in a typical task, using your own task history where possible.

5. Use capacity for planning
Compare billable hours with your target rate, and treat the task count as an approximate scheduling limit rather than a demand prediction.

Formula:

Weekly billable hours = Available hours × (1 − Non-billable % ÷ 100) Annual billable hours = Weekly billable hours × Working weeks Task capacity = Billable hours ÷ Average billable hours per task

The task count may be fractional because it represents average capacity across a period rather than a literal partial task.

What the result means

The result shows how much of your weekly marketplace workload remains sellable after the overhead percentage you entered.

High proposal or travel time can materially reduce practical capacity even when total availability is unchanged.

Given: 28 available hours per week, 32% non-billable time, 45 working weeks, and 3.2 billable hours per task.

Calculation: Weekly billable hours = 28 × 0.68 = 19.04 hours. Annual billable hours = 19.04 × 45 = 856.8 hours. Weekly task capacity = 19.04 ÷ 3.2 = 5.95 tasks.

Result: About 19.0 billable hours and 6 average-sized tasks per week.

What belongs in non-billable time?

Include task-search time, proposals, unpaid client communication, travel that is not separately paid, bookkeeping, and similar overhead you want excluded from sellable hours.

Can I enter a different task size for each service?

Run the calculator separately for each service type if their average task lengths differ substantially. A blended average is more useful only when your task mix is fairly stable.

Why is task capacity shown with decimals?

It represents an average over time. A value of 5.8 tasks per week might mean five tasks in one week and six or seven in another.

Does this estimate guarantee I can fill all billable hours?

No. It estimates capacity, not client demand or marketplace availability.

How does this connect to a required rate?

Annual billable hours can be used as the capacity input in a required-rate calculation so your income target is spread only across realistically sellable time.
