Profitability calculators and formulas

What profitability measures

Profitability is revenue minus the costs included in the decision. Margin divides that profit by revenue; markup divides it by cost. Break-even finds the volume needed to cover fixed and variable costs, while ROI compares an investment gain with the initial investment. Choose the calculator that matches the question, then verify the result against source records.

Price and margin

Move from cost to price, then distinguish margin from markup.

• Markup calculator: Calculate price from markup or convert markup to margin.
• Selling price calculator: Set a selling price from cost, target margin or target profit.
• Break-even calculator: Find the units and revenue needed to cover entered costs.

Return and project economics

Compare an investment plan with the economics of actual delivery.

• ROI and payback calculator: Calculate ROI, annualized return, return multiple and payback.
• Project profitability calculator: Compare project revenue with expenses and delivery labor.
• Client profitability calculator: Review client profit, margin and profit per service hour.
• Retainer profitability calculator: Compare retainer revenue with used hours and direct costs.

Templates and evidence

Move from a quick calculation to a repeatable, source-linked review.

• Project budget template: Compare planned and actual hours, expenses and budget variance.
• Client profitability template: Review multiple clients with delivery and acquisition costs.
• Retainer profitability tracker: Track planned and used hours and effective hourly rate.

Profitability formula reference

Profit

Revenue − included costs. Use revenue and costs from the same scope and period.

Profit margin

Profit ÷ revenue × 100. Margin uses revenue as the denominator.

Markup

Profit ÷ cost × 100. Markup uses cost as the denominator.

Break-even units

Fixed costs ÷ (unit price − variable cost). A positive contribution per unit is required.

ROI

Net return ÷ initial investment × 100. Compare time, risk and omitted cash flows as well as the percentage.

Profitability toolkit FAQ

Which profitability calculator should I use?

Use profit margin for revenue and cost, markup for cost-based pricing, selling price for a target margin, break-even for required sales volume, ROI for an investment return, and project, client or retainer calculators when delivery time and direct costs matter.

What is the difference between margin and markup?

Margin divides profit by revenue, while markup divides profit by cost. The same sale therefore produces different margin and markup percentages.

Are these calculators accounting reports?

No. They are planning tools based on the values and scope you enter. Verify material decisions against invoices, payments, expenses, task costs and appropriate professional advice.

Are entered amounts saved?

No. Calculator inputs and results stay in the browser unless you deliberately download or print them. FollowIncome analytics do not include entered financial values or calculated results.
