About Invoice Generator
Running a small business means wearing every hat at once — and business-critical numbers like break-even points, markup percentages, and invoiced amounts need to be right even when time is short. Invoice Generator handles one of those recurring calculations quickly and transparently, so you can make a confident decision and move on.

- Export or copy the output to paste into a quote, invoice, or business plan.
Frequently asked questions
- What is the difference between markup and margin?
- Markup is the percentage added to cost to reach selling price (profit/cost). Margin is the percentage of selling price that is profit (profit/selling price). At 50% markup you achieve a 33% margin — they are not the same number.
- Does the tool include VAT or sales tax in its calculations?
- Tax-inclusive tools add the specified rate to the net figure. If the tool shows 'ex-tax' figures, add your applicable rate separately.
- Can I use this for service-based businesses as well as product-based?
- Yes. Replace 'cost of goods' with your billable cost of time and materials. The margin and markup logic is identical.
- Are the figures I enter sent to any third party?
- No. All calculations are browser-local. Your business figures are private.
- Is a break-even calculation the same as a profitability forecast?
- No. Break-even tells you the minimum units or revenue to cover fixed and variable costs. Profitability forecasting additionally projects revenue growth, seasonality, and longer-term overheads.
