Pricing & Margin Calculator
Your pricing and margins are unclear, so you can't tell which jobs actually make money.
You get
A clear margin breakdown and pricing options laid out for you to decide on.
- Who it's for
- Owners who want to see their numbers clearly before setting prices.
- When to use it
- When you're reviewing pricing or trying to understand margins on a job or service.
- What it needs
- Your costs
- Current prices
- Any target margin
- What it produces
- A margin analysis with the math shown and pricing options to consider, decisions stay with you.
- Files you receive
- Three formats, so it works with whatever you already use:
- Claude — Installable skill package (.zip). In Claude: Settings → Capabilities → Skills → Create skill → Upload a skill. Upload the ZIP without unzipping it, then turn the skill on.
- ChatGPT — Custom GPT instructions (.md). In ChatGPT: create a new Custom GPT, then paste the instructions file into the Instructions field.
- Universal — Copy-and-paste prompt (.md). Open the file, copy the whole thing, and paste it into a new chat with any AI assistant.
- Time to first result
- 20 to 40 min per review
The owner says
"House wash: supplies $40, 3 hours labor at $60 an hour, I charge a flat $325. What's my margin and what would 50% look like?"
It hands back
INPUTS (yours) Supplies $40 · Labor 3h × $60 = $180 · Price $325 · (no overhead % provided) THE MATH, SHOWN Job cost = 40 + 180 = $220 Gross profit = 325 − 220 = $105 Gross margin = 105 / 325 = 32.3% TO HIT 50% MARGIN Price = cost / (1 − 0.50) = 220 / 0.5 = $440 (Or cut cost to $162.50 at the current $325 price.) Assumptions: $60/hr is your loaded labor cost, not wage; overhead not yet included — give me your monthly overhead and I'll fold it in. This is arithmetic on the numbers you gave me — a pricing aid, not financial advice.
Illustrative example — not a customer result.
How it works
- 1Takes your costs, prices, and targets.
- 2Shows the margin math step by step.
- 3Lays out pricing options to consider.
- 4Frames everything as analysis support, never advice, and escalates tax/accounting questions.
Catches what is slipping
Catches the service priced below your target margin.
You show it
Your cost and price list, with target margins if you have them
What gets flagged
- Flags items whose margin falls below your target
- Flags prices that have not been reviewed in about 6 months
- Never invents a target; if none is set, it shows the math and asks
It lays out options with the math visible. Analysis support, not financial advice, and it never tells you what to charge.
What you need to run it
You need an account with an AI assistant — Claude, ChatGPT, or another. Installing skills in Claude and creating Custom GPTs in ChatGPT both need those providers' paid plans; the copy-and-paste version works on any plan. See Anthropic's help center for what your plan includes. (Last verified 2026-08-02.)
Works well with
Cash Flow Review Assistant
You feel your cash flow rather than see it, there's no simple day to day picture.

Proposals are slow and inconsistent, so they go out late and look different every time.
