General questions
Basic questions about what the calculator measures.
What does the Accountants Project Profit (Hourly) Calculator estimate?
It estimates gross revenue, net revenue after expected write-offs, project cost, profit, profit margin, and effective hourly revenue for an hourly engagement.
Who can use this calculator?
It can be used for planning or reviewing accounting, bookkeeping, tax, audit, advisory, and similar professional-service projects billed by the hour.
Is project profit the same as cash received?
No. The calculation estimates profitability from expected revenue and costs. It does not model invoice timing, collections, or cash flow.
Is the result before or after tax?
The result is before business taxes, interest, owner drawings, and costs not entered.
Revenue and write-offs
Questions about billed value, revenue recovery, and effective rates.
What is gross project revenue?
Gross project revenue is billable hours multiplied by the hourly billing rate before any expected write-offs or discounts.
What is net project revenue?
Net project revenue is gross revenue reduced by the write-off rate entered in the calculator.
What does write-off rate mean?
It is the percentage of gross billing value expected to be discounted, written off, or otherwise not recovered from the client.
How is effective hourly revenue calculated?
It is net project revenue divided by billable hours. It reflects expected recovered revenue per billable hour after write-offs.
Costs and profit margin
Questions about labor, overhead, direct costs, and margins.
What should be included in staff cost per hour?
Use the hourly delivery cost that fits the firm's costing approach. It may include pay-related costs where appropriate.
What is overhead per hour?
It is an allocation of indirect operating costs to each billable project hour, such as office, technology, management, and administration costs.
What are other direct project costs?
These are fixed costs directly attributable to the engagement, such as subcontractors, travel, specialist tools, or filing charges.
How is profit margin calculated?
Profit margin equals estimated project profit divided by expected net revenue, multiplied by 100.
Can a project have a negative margin?
Yes. If total project cost is greater than expected net revenue, the calculation produces a loss and a negative margin.
Accuracy and use
Questions about interpreting and updating the estimate.
How accurate is the calculator?
It is only as accurate as the hours, billing rate, write-off allowance, and cost estimates entered. Actual profitability may differ.
Should partner or manager time be included?
Include it when the firm wants the estimate to reflect the economic cost of all time used on the engagement. The appropriate internal cost rate varies by firm.
Can I use the calculator for completed work?
Yes. Replace planned inputs with actual hours, costs, and recovered revenue to review the realized result.
What does a low margin indicate?
It indicates that a relatively small share of expected net revenue remains after the entered costs. Review the underlying assumptions and compare the result with internal targets.
How do you calculate profit on an hourly accounting project?
Subtract labor cost, allocated overhead, and other direct costs from expected net revenue after write-offs.
