How to calculate a service price
Add the cost of your labor, materials and other direct expenses, plus a reasonable share of overhead for the job. Divide that total by one minus the target margin as a decimal.
Price before tax = entered costs ÷ (1 − target margin)
For example, two hours at $35 per hour, $20 in materials and $10 in allocated overhead add up to $100. At a 30% target margin, $100 ÷ 0.70 gives a price of $142.86 before tax. The difference of $42.86 is profit after the costs you entered, before any unlisted expenses and income tax.
Margin and markup use different starting points.
Margin is profit as a percentage of your selling price. Markup is the amount added as a percentage of your costs. Adding 30% to $100 gives a $130 price, which has a margin of about 23.1%. A 30% margin on those same costs requires a price of about $142.86.
Turn the estimate into a price you can stand behind.
Check your inputs against real jobs. Include time for preparation, travel and revisions when they belong to the service. Allocate overhead once, so you do not count the same expense in both direct costs and overhead. Decide whether your final quote needs a minimum charge, a scope allowance or a different rate.
This is a planning estimate based on the numbers you enter. It does not choose your tax rate or account for costs you leave out. Currency selection changes the label and does not convert amounts.
