How this tool works

This calculator subtracts direct costs, payment fees, and an operating buffer from project revenue, then estimates gross profit, margin percentage, break-even price, target price, and optional tax reserve.

Formula or template logic

paymentFees = projectRevenue * paymentFeePercentage / 100; operatingBuffer = projectRevenue * operatingBufferPercentage / 100; totalProjectCosts = directCosts + paymentFees + operatingBuffer; grossProfit = projectRevenue - totalProjectCosts; margin = grossProfit / projectRevenue * 100; breakEvenPrice = directCosts / (1 - paymentFeePercentage / 100 - operatingBufferPercentage / 100); targetPrice = directCosts / (1 - paymentFeePercentage / 100 - operatingBufferPercentage / 100 - targetMarginPercentage / 100)

Example use case

Use this after estimating a project price to check whether the fee still leaves enough margin after production costs, fees, operating buffer, and tax reserve.

Frequently asked questions

What is project profit margin?

Project profit margin is the share of project revenue left after direct costs, fees, and operating buffer are removed.

Why include a break-even price?

Break-even shows the minimum price needed to cover the listed direct costs and percentage-based costs before profit.

What is a target price?

The target price estimates what you would need to charge to reach your desired margin after costs and percentage-based fees.

Should tax reserve affect profit margin?

This tool shows tax reserve separately as a planning number. Margin is calculated before tax reserve so it stays comparable across projects.

Is this accounting advice?

No. It is a planning calculator. Confirm taxes, bookkeeping, and cost treatment with a qualified professional.
