Job Markup & Profit Margin Calculator
Enter your material and labor costs and a target profit margin to see exactly what to charge — and how much profit you'll make. Stop guessing and start pricing every job for profit.
Total job cost: $500.00. Margin is the share of the price that is profit; markup is profit as a share of cost. Enter a margin below 100%.
Why pricing for margin matters
Underpricing is one of the fastest ways for a service business to go broke while staying busy. Pricing from a target margin — rather than just adding a vague markup — makes sure every job covers your overhead and leaves real profit. A small change in margin can be the difference between a thriving shop and a struggling one: moving from a 35% to a 45% margin on the same costs raises your take on a $500 job by nearly $140.
Margin vs. markup — and why the difference costs you
Markup is profit measured against your cost. Margin is profit measured against your price. They describe the same dollars from different angles, and mixing them up is the single most common pricing error in the trades. Because the price is always larger than the cost, the margin percentage is always smaller than the markup percentage:
- A 50% markup is only a 33.3% margin.
- A 66.7% markup equals a 40% margin.
- A 100% markup (doubling cost) equals a 50% margin.
If you think you're "adding 40%" but you're adding it to cost, you're actually running a 28.6% margin — and very possibly not covering overhead.
The formula and a worked example
Suppose a job costs $200 in materials and $300 in labor, for a $500 total cost, and you want a 40% margin. Price = $500 ÷ (1 − 0.40) = $500 ÷ 0.60 = $833.33. Your profit is $333.33, which is exactly 40% of the price — and a 66.7% markup on cost. The calculator above shows all three figures the moment you type your numbers.
What margin should I target?
There's no universal number, but many service businesses aim for gross margins of 40–50% on direct costs. Your target has to clear two hurdles: cover overhead (rent, vehicles, insurance, software, office staff) and then leave net profit on top. If overhead eats about 25% of revenue, a 40% gross margin leaves roughly 15% net before taxes. Trades with high overhead or heavy callback risk often need to price higher.
Common pricing mistakes
- Confusing markup with margin and quietly running below target.
- Treating labor as a straight cost instead of marking it up to cover taxes, benefits, and profit.
- Forgetting to bake overhead into the margin target, so " profitable" jobs still lose money at year-end.
- Discounting on the spot without recalculating what the new price does to margin.
How software makes consistent pricing effortless
Doing this math by hand on every estimate invites errors and inconsistency. A price book fixes that: build your flat-rate items once at the margins you need, and every quote prices itself.
Service Storm lets you send multi-option quotes from a price book, then turns approved work into scheduled jobs, invoices, and payments automatically — so the margin you priced is the margin you collect.
