Calculators for small-business decisions
Each calculator runs entirely in your browser. Nothing you type is transmitted, logged or stored, and none of them ask for an email address.
Websites
Website Cost Estimator
Estimate a realistic build range from your page count, design approach, content readiness and features — plus the annual running cost most quotes leave out.
Marketing
Google Ads Budget Calculator
Work backwards from average sale value, margin and close rate to the cost per click and monthly budget your business can actually sustain.
Pricing
Profit Margin Calculator
Convert between cost, price, gross margin and markup — and see the price required to hit a target margin.
Finance
Break-Even Calculator
Turn fixed costs, price and variable cost per sale into a monthly and weekly break-even target, with your margin of safety.
Pricing
Hourly Rate Calculator
Set a defensible hourly rate from your target income, overheads, realistic billable hours and a profit buffer.
In development
We would rather publish five calculators that work properly than a dozen rough ones. These are next, and they use the same architecture:
- Business Expenses Tracker — Category-level monthly expense planning
- Marketing ROI Calculator — Return by channel over a chosen period
- Cash Flow Forecaster — 13-week rolling forecast
