How the numbers are calculated
Example in a high-income eurozone country, at month 12: revenue €2,400 − costs €800 = €1,600 net per month. Revenue: 25 freelancers × €80 + 4 tax returns × €100. Costs: accounting software, liability insurance, computer, prospecting, social contributions. For other countries, Mundyo adjusts the starting budget to the price level (World Bank) and the income to prices and customers' purchasing power, then converts at the day's exchange rate.
