About this workspace
Pricing a project, checking whether the numbers work, and estimating what the tax office will take - these calculators answer the money questions small businesses and freelancers actually face. Enter your figures and results update instantly, with the working shown so you can sanity-check the output.
The set covers business fundamentals (break-even point, profit margin and markup, cash-flow runway, platform fees), personal money (take-home salary, monthly budget, loan EMI), freelance pricing (hourly rate planning, hourly versus fixed fee), and region-specific tax (India GST, TDS and presumptive tax, US self-employment tax, UK late payment interest).
All results are estimates for planning, computed locally in your browser - your income and expense figures are never transmitted anywhere. For filing decisions, confirm the numbers with an accountant; tax rules change and edge cases are real.
