Quick-reference markup vs. gross profit margin table
Common minimum floor for large material-heavy subcontracts; leaves thin room if overhead exceeds 20%.
Healthy baseline for multi-day installations, remodels and residential project quotes ($650 cost → $1,000 quote).
Strong target for skilled trade repairs, electrical/plumbing upgrades and specialty service work ($550 cost → $1,000 quote).
Standard target for rapid diagnostic repairs, small service calls and stocked truck-part replacements ($500 cost → $1,000 quote).

Markup-to-Margin Conversion Cheat Sheet (Keep This in the Truck)
Never multiply by 1.30 when you need a 30% gross margin. Use the divisor or multiplier below.
Target Gross Margin %Exact Formula (Cost ÷ Divisor)Required Markup % (Cost × Multiplier)
20% Gross Margin — Typical only for high-ticket pass-through equipmentDirect Cost ÷ 0.8025.0% Markup (× 1.250)
30% Gross Margin — Entry project target (e.g., $700 cost → $1,000 price = $300 gross profit)Direct Cost ÷ 0.7042.9% Markup (× 1.429)
40% Gross Margin — Healthy trade install target (e.g., $600 cost → $1,000 price = $400 gross profit)Direct Cost ÷ 0.6066.7% Markup (× 1.667)
50% Gross Margin — Service & repair callout benchmark (e.g., $500 cost → $1,000 price = $500 gross profit)Direct Cost ÷ 0.50100.0% Markup (× 2.000)
Why it matters: If your company overhead (vans, insurance, office, marketing, unbillable time) is 28% of revenue and you price jobs at a 25% markup (which is only a 20% margin), you lose 8 cents on every dollar you build.
The everyday workflow
How to price a job for healthy gross margin in 4 steps
Tally true direct labour cost
Count all on-site hours plus prep, travel and cleanup time, multiplied by your burdened hourly labour cost.
Add materials, parts and equipment rentals
Include fittings, fasteners, consumables and supplier delivery fees so small parts don’t erode your margin.
Divide by (1 − target gross margin)
For a 35% gross margin on $600 of direct cost, divide $600 by 0.65 to get a $923 quote price ($323 gross profit, which is a 53.8% markup).
Present clear line items on your quote
Put your calculated labour and material lines into a professional Service Zen quote so the client can approve online.

Markup vs. margin quick reference for service pros
The difference in one sentence
Margin is profit divided by the selling price; markup is profit divided by your cost. Because your cost is smaller than your selling price, your markup percentage must always be higher than your target margin percentage.
Common target margins in the trades
To achieve a 25% margin, apply a 33.3% markup. For a 35% margin, apply a 53.8% markup. For a 40% margin, apply a 66.7% markup. For a 50% margin, apply a 100% markup (2× cost).
Keep your quotes consistent across the team
When estimators and technicians build quotes inside Service Zen using structured line items, your office can review pricing before the estimate goes out or the invoice is sent.
Inside Service Zen
A few useful answers
Before you get started.
What is the formula to convert cost and target margin into a quote price?
Divide your total direct cost (labour + materials) by (1 − target margin as a decimal). For example, $500 cost at a 40% margin is $500 ÷ (1 − 0.40) = $833.33.
What is the formula to convert markup percentage into profit margin?
Margin = Markup ÷ (1 + Markup). For example, a 50% markup (0.50) equals 0.50 ÷ 1.50 = 33.3% gross profit margin.
Can I build and send quotes directly in Service Zen?
Yes. Service Zen includes a full quoting and estimating workflow that connects approved estimates directly to job scheduling and invoicing.
