Trace an $80,000 goal into a quote.

Four weeks off leave 48 working weeks. At 40 total business hours per week, the year contains 1,920 working hours. The 70% billable utilization assumption means 30% of that time supports proposals, administration, bookkeeping, scheduling, marketing, learning, and gaps between client assignments.

Annual billable capacity is 48 x 40 x 0.70 = 1,344 hours. The other 576 hours are not removed from the business. Their cost is spread across the 1,344 hours that can reach an invoice. Dividing by 1,920 would assume every operating hour has its own source of revenue and would understate the client rate.

The 28% tax set-aside and 12% variable overhead consume 40% of gross revenue. That leaves 60% for the take-home target because there are no fixed costs in this example. Required revenue is therefore $80,000 / 0.60 = $133,333.33.

A simple markup would calculate $80,000 x 1.40 = $112,000. Applying the same 40% allowances to $112,000 would leave only $67,200, which misses the goal by $12,800. Margin reversal solves for the gross amount whose remaining 60% equals the target.

1. Working weeks52 - 4 = 48 weeks

   Remove full weeks that cannot support delivery or operations.

2. Billable capacity48 x 40 x 70% = 1,344 hours

   Apply utilization once to total business time.

3. Gross revenue($80,000 + $0) / (1 - 28% - 12%) = $133,333.33

   Reverse the combined revenue-linked allowances.

4. Hourly floor$133,333.33 / 1,344 = $99.21

   Round upward to a $100 client-facing hourly quote.

5. Day quote$100 x 8 hours x 1.15 = $920

   Use the full reserved day. Do not apply utilization again.

The exact floor is $99.21, while the displayed quote is rounded upward to $100. If every planned billable hour is sold at exactly $100, annual invoiced revenue would be $134,400. That is about $1,066.67 above the unrounded revenue requirement.

This buffer is a consequence of whole-dollar pricing, not an additional target or hidden fee. It can help absorb minor timing variation, but it should not be treated as protection against a major utilization miss. If only 60% of working hours become billable, the plan needs a different rate calculation rather than reliance on rounding.

The table changes one default assumption at a time and leaves all others fixed. It is a sensitivity check, not a recommendation. The comparison shows why a rate without documented assumptions is difficult to evaluate.

The example assumes the quoted hours are sold, invoiced, and collected without bad debt, currency conversion, subcontractor costs, or scope expansion. It does not include employee benefits, retirement goals, health insurance, sales tax, payment processing, or a profit target unless the user represents those needs in the take-home goal, fixed costs, or overhead allowance.

The tax set-aside is an editable pricing factor only. It does not calculate federal or state liability, deductions, filing status, or quarterly payments. The BLS occupation comparison available on the homepage is employee wage context and is not part of this example's core math.
