Business Calculators
ROI, margins, break-even and cash flow — the metrics that run a business.
Profitability Calculator
Revenue is vanity, profit is sanity. This calculator takes your revenue and total expenses and gives you the three numbers that matter: absolute profit, profit margin and markup.
ROI Calculator
Is an investment worth it? ROI tells you how much you earn per euro invested, and the annualized figure lets you compare opportunities of different durations fairly.
ROAS Calculator
A high ROAS looks great, but profit is what pays the bills. This calculator shows your ROAS, the profit behind it, and the break-even ROAS you must exceed to actually make money.
Gross Margin Calculator
Gross margin shows how efficiently you produce and sell your product before overheads kick in. This calculator gives you gross profit, gross margin and the markup implied by your pricing.
Net Margin Calculator
Gross margin tells you about your product; net margin tells you about your business. After every cost is paid, what percentage of revenue is actually yours?
Sale Price Calculator
Cost-plus pricing is a recipe for margin erosion. This calculator works the other way: you decide the margin, and it tells you the price that guarantees it.
Break-even Calculator
Before you make a euro of profit, you must cover your costs. This calculator finds the exact sales volume and revenue where you break even — and where profit begins.
Cash Flow Calculator
Profit is not cash. This calculator compares your monthly income with your monthly expenses to show what actually remains — your monthly surplus, its annual total and your savings rate.
Salary After Tax Calculator
Your gross salary is not what lands in your bank account. Income tax and social contributions take a slice first. This calculator shows you exactly what you keep.
Hourly Salary Calculator
Annual pay is a full year of work. But your time is traded hour by hour. This calculator converts your yearly salary into the hourly, daily, weekly and monthly figures you can actually plan with.
Freelance Hourly Rate Calculator
Underpricing is the freelancer's most expensive mistake. This calculator builds your rate from the ground up: target income, billable hours, expenses and margin — so the number you quote is the number you can live with.
Freelance Rate Calculator
A bare hourly rate hides overheads and profit. This calculator layers overheads and a profit margin on top of your base rate, producing the final rate you actually invoice.
Loan Amortization Calculator
A loan's real cost is the interest, not just the monthly payment. This calculator gives you the full picture: the fixed monthly payment, the total repaid and the total interest over the entire term.
Car Loan Calculator
The sticker price is only the start. Financing adds interest, and your down payment shapes both. This calculator turns a vehicle price and down payment into the monthly payment and total cost.
Down Payment Calculator
The price tag is not what you pay upfront. A property purchase needs a down payment, purchase fees and often a loan. This calculator breaks down exactly how much cash you need before you sign anything.
Rental Yield Calculator
Is a rental property worth it? The answer starts with yield. This calculator gives you the gross yield everyone quotes, then the net yield that actually reflects your costs — the number that matters.

A ROAS above your break-even ROAS is profitable. For a 40% margin, break-even is 2.5x, so aim above that after accounting for all costs.
Margin is profit divided by the selling price. Markup is profit divided by the cost. A 60% margin equals a 150% markup.
