How to Price a Project

Pricing is not guessing. It is arithmetic: gather every cost, allocate overheads, choose your target margin, and calculate the price that delivers it. The Margin Calculator does the maths; this guide shows the workflow.

The pricing workflow (do these in order)

  1. 1

    List every direct cost

    Open a spreadsheet. For this project, what will you spend that you would not spend otherwise?

    • Subcontractor / freelancer fees
    • Stock assets (photos, fonts, illustrations, code)
    • Licences / plugins bought for this job
    • Print, fabrication, manufacturing
    • Hardware resold to the client
    • Payment processing fees (a percentage of the invoice plus a small fixed fee)
    • Travel / materials specific to this project

    Sum these. This is your Cost field in the Margin Calculator.

    On the payment fees: card and wallet processors all charge roughly a few percent plus a fixed amount, but the exact figure depends on your country, the card type the client uses, whether the charge is treated as international, and the plan you are on — and they change. Take the real number from your own provider’s pricing page or dashboard rather than from a guide, because getting it wrong by half a percent on a large invoice is real money and the number is free to check. The worked example below uses 3% as a round placeholder for that reason.

  2. 2

    Allocate overheads to this job

    Overheads exist whether this project happens or not. But each project should carry its fair share. Common methods:

    • Time-based: (Your hours on this job ÷ Total billable hours this month) × Monthly overheads
    • Revenue-based: (Project revenue ÷ Total monthly revenue) × Monthly overheads
    • Flat per project: Fixed admin fee (e.g., £200/project) — simple but less accurate

    Enter this in the Overheads field. It drives the Net profit and Net margin figures.

  3. 3

    Choose your target gross margin

    This is a business decision, not a calculation. Typical ranges:

    • Pure service (low direct cost): 50–70% gross margin
    • Mixed (some pass-through): 30–50% gross margin
    • Heavy pass-through (media, print, hardware): 15–30% gross margin

    Enter this in Target gross margin. The calculator shows the exact price you need to quote.

  4. 4

    Check the net margin

    The calculator shows Net margin (after overheads). If it's below ~15–20%, the project may not be worth the administrative burden unless it's strategic (portfolio, relationship, repeat work).

  5. 5

    Round the quote sensibly

    The calculator gives £6,666.67. Quote £6,700 or £6,750. The extra £33–83 is a buffer for scope creep or underestimated hours.

  6. 6

    Run the tax calculation

    If you charge VAT/GST, the client pays the gross. Your net revenue is the quote. Use the Tax Calculator in Tax exclusive mode to confirm the gross total the client sees.

  7. 7

    Build the invoice

    Use the Invoice Generator. Reference the quote number in the PO field. The invoice total should match the quoted price exactly.

Worked example: a website project priced to a 50% margin

The subtlety is that payment fees are a percentage of the price you are still in the middle of choosing, so you cannot simply add them to the costs and divide. If you divide first and add the fee afterwards, the margin comes out slightly under target every single time. Solve for the price instead:

Price = Fixed costs / (1 − fee rate − target margin)
Worked example: pricing a website project to a 50% gross margin, including payment fees
Subcontractor (copywriter)1,500.00
Stock photos / fonts300.00
Plugin licence (project-specific)150.00
Fixed costs1,950.00
Payment fee rate (check your own plan — see below)3%
Target gross margin50%
Solved price = 1,950 / (1 − 0.03 − 0.50)4,148.94
Price you quote (rounded up, never down)4,150.00

Then the quote itself, checked back:

The quoted price verified: 50.0% gross margin, 44.0% net margin
Quoted price, excluding VAT4,150.00
Payment fees (3% of 4,150.00)124.50
Total direct cost2,074.50
Gross profit2,075.50
Gross margin (hit the target, as intended)50.0%
Overheads allocated (20 hrs of a 160 hr month × £2,000)250.00
Net profit1,825.50
Net margin44.0%
VAT at 20% (your problem, the client’s cost)830.00
Client pays in total4,980.00

Note that the gross margin lands on 50.0% and not slightly under it, which is the whole point of solving rather than dividing. And note that the 6 percentage points between gross and net margin are not a rounding error — they are the cost of running a business during the two months you are waiting to be paid.

Common pricing traps

Deposit and milestone pricing

Split the quoted price into milestones. Common patterns:

Each milestone gets its own invoice with its own sequential number. Reference the project and quote in the notes.
