Understand the difference between common business metrics before using them in a plan, quote or spreadsheet.
Profit margin vs. markup
Profit margin compares profit with revenue. Markup compares the difference between selling price and cost with the original cost. The percentages are not interchangeable.
Use the Profit Margin Calculator for margin, the Markup Calculator for markup, and the Unit Price Calculator to compare pack sizes.
Break-even and contribution
Break-even analysis estimates the sales volume needed to cover fixed costs after variable costs are accounted for. Contribution per unit is selling price minus variable cost per unit.
The Break-even Calculator lets you test how a change in price or cost affects the required units. It does not predict demand or guarantee profit.
ROI and annualized growth
Return on investment (ROI) compares a gain or loss with the original investment. Compound annual growth rate (CAGR) expresses growth between a starting and ending value as an annualized rate.
Use the ROI Calculator and CAGR Calculator for historical or hypothetical comparisons—not predictions.
Sales commission and pricing
Commission calculations commonly multiply eligible sales by a commission rate. Real compensation plans can also include tiers, thresholds, returns and exclusions.
Start with the Commission Calculator, then use the Price Increase Calculator or Discount Calculator to explore pricing changes.
VAT, sales tax and discounts
VAT and sales tax calculations depend on the rate and tax treatment you enter. Rules can vary by jurisdiction, product, service and business status.
The VAT Calculator and Sales Tax Calculator perform arithmetic; they do not determine which legal rate applies.
Salary and operating costs
Salary comparisons may involve working hours, overtime, allowances, benefits, deductions and local employment rules. A simple pay conversion is only a starting point.
Try the Salary Calculator and Hourly to Salary Calculator. Confirm payroll requirements separately.
Choosing the right calculator
- For profitability relative to revenue, choose profit margin.
- For price increase over cost, choose markup.
- For required sales volume, choose break-even.
- For investment returns, choose ROI; for annualized growth, CAGR.
- For pay or tax, confirm the applicable assumptions first.
How to interpret the results
Use consistent currencies and time periods. Check whether values are before or after tax, whether costs are fixed or variable, and whether results have been rounded.

Business calculators: frequently asked questions
Are ToolZippy business calculators free?
Yes. These calculator pages are available without requiring an account.
What is the difference between profit margin and markup?
Profit margin is profit divided by revenue. Markup is the amount added above cost divided by cost. They use different denominators and give different percentages.
Can I use break-even results for business planning?
Yes, for simplified scenario planning. Actual results can change with demand, taxes, capacity, financing and other costs not included in the formula.
Do ROI and CAGR predict future returns?
No. They describe results based on the figures entered. They are not forecasts or investment advice.
Are VAT and sales tax results official?
No. The tools use the rates you enter. Confirm the correct rates, exemptions and reporting requirements from relevant official sources.
Can I use these calculators on mobile?
ToolZippy calculators are designed for modern mobile and desktop browsers. The directory also adapts to smaller screens.
Why might a result differ from my accounting software?
Differences can arise from rounding, accounting methods, tax treatment, timing, discounts, fees or inputs that are not included in a simplified calculation.
