Start with the cost.
Then choose the price.

Use your own numbers to estimate one job. This calculator uses all entered costs, including overhead, as its pricing base. It is a simplified teaching tool, separate from the workbook's gross-margin workflow.

Include your own working time in labor. Overhead is entered separately. This simplified estimate is before sales tax, discounts, payment fees, and other unentered costs. It does not reproduce every feature of the workbook.

What the result means

The calculator adds labor, materials, travel, and allocated overhead. It then applies your chosen markup or a margin on that complete cost base. This makes the displayed margin a surplus after entered overhead; it should not be confused with gross margin calculated on direct costs alone.

Markup: price = cost × (1 + percentage)
Margin: price = cost ÷ (1 − percentage)

Prices are rounded to cents. If you enter no costs, the result is zero. A 100% margin has no finite price. Unentered expenses, discounts, taxes, payment fees, rework, and market demand can change your actual outcome.
