What should I start with?
Most side-income advice hands you a list of ideas and leaves you to work out whether any of them fit. Income Toolkit goes the other way round: the tools come before the articles.
The Idea Finder takes your budget, your skills, the hours you have free and the type of work you prefer. It returns a short list of fitting opportunities with the tools each one needs. The calculators then show their working: every assumption is on screen, and every figure is labelled as an estimate, not earnings.
How it works
Three steps, in this order:
Tell it four things. Your budget, your skills, the hours you have free and the type of work you prefer.
Read the short list. Each fitting opportunity comes with the tools it needs.
Check the working. The calculators show their assumptions, so you can see what every estimate rests on.
Six tools, each one showing its working
One Idea Finder and five calculators. All of them label every figure as an estimate, not earnings.
