This synthetic job uses USD to make the arithmetic inspectable. The prices, rates and tax settings are examples; enter your own currency, supplier prices and applicable tax basis.
1. Cost the stock you purchase
Four confirmed 1,000 mm blanks fit on two 2,400 mm boards, two blanks per board. With 3 mm kerf and 5 mm at each end, each board consumes 2,016 mm and leaves 384 mm. At USD 14.00 per board, the material purchase is USD 28.00.
Purchased length is 4,800 mm: 4,000 mm in finished blanks, 32 mm of kerf/end loss and 768 mm of offcuts. The USD 28.00 already pays for all of it. Adding a second “waste cost” would charge the same purchase twice.
2. Build the pricing budget
| Included item | Calculation | Cost |
|---|---|---|
| Purchased stock | 2 × USD 14.00 | USD 28.00 |
| Labor cost | 6 hours × USD 30.00 | USD 180.00 |
| Consumables | Entered allowance | USD 12.00 |
| Travel | Entered job expense | USD 10.00 |
| Allocated overhead | Entered allocation | USD 30.00 |
| Contingency reserve | None in this example | USD 0.00 |
| Pricing cost | Sum of included items | USD 260.00 |
The USD 30.00 hourly figure is a cost rate, not an hourly customer selling rate. Overhead is added once. If you add a contingency, keep it visible as a planned reserve; it becomes an actual cost only when money is spent and recorded.
3. Set margin deliberately
A 25% target margin means price = 260 ÷ (1 − 0.25) = 346.666… . Rounding the final price once to cents gives USD 346.67 pretax. Planned profit against the budget is 346.67 − 260.00 = USD 86.67. Its displayed margin rounds to 25.00%; equivalent markup rounds to 33.33%.
A 25% markup would give 260 × 1.25 = USD 325.00 and USD 65.00 of planned profit. That is a 20% margin. The percentages are not interchangeable.
4. Keep tax separate
Tax starts off. For this arithmetic example only, suppose you explicitly select a tax-exclusive taxable amount of USD 200.00 and a rate of 10%. Tax is 200.00 × 0.10 = USD 20.00. The customer total is 346.67 + 20.00 = USD 366.67.
The selected taxable amount does not imply that materials, labor or the whole quote are legally taxable. Confirm the rules that apply to your transaction. Collected tax is excluded from pretax revenue, profit and margin.
5. Review the customer document
Describe the agreed work, inclusions, exclusions and validity dates. Review the customer-facing sell prices and total before exporting. Supplier prices, labor cost rates, internal margins, actuals and private notes are excluded from the customer document model. A workshop plan and a full backup serve different purposes and contain more information.
6. Compare the completed job
Suppose the completed job has recorded actual costs of USD 360.00 and actual pretax revenue of USD 400.00 after an agreed scope change. Actual job profit is USD 40.00; actual margin is 10%. Record the change and keep the original quote snapshot.
| Figure | Estimate | Actual | Change |
|---|---|---|---|
| Cost | USD 260.00 | USD 360.00 | +USD 100.00 |
| Pretax revenue | USD 346.67 | USD 400.00 | +USD 53.33 |
| Job profit | USD 86.67 | USD 40.00 | −USD 46.67 |
| Margin | 25.00% | 10.00% | −15.00 percentage points |
Higher revenue did not mean higher profit. These figures include only the costs you recorded; they do not establish whole-business net profit. Review extra hours, purchases and omitted expenses before using the job to inform the next estimate.
