The idea

Income is money that comes to you over a period of time. Most of it arrives in a few familiar forms. A salary is a fixed yearly amount paid in regular instalments. Hourly income is paid for each hour worked, so it rises and falls with your hours. Freelance income is paid per project or task by several clients. Business income is what is left after a business pays its costs. Commission is a share of what you sell.

Each form behaves differently. A salary is predictable but usually capped; hourly and freelance income can grow with effort but are exposed to slow periods; commission and business income can be large in good times and very small in bad ones. Gross income is what you earn before deductions such as tax and contributions; net income is what actually reaches you. Budgets need to be built on net income.

Why it matters

Knowing how your income behaves — steady or lumpy, capped or open-ended — decides how much buffer you need, how you budget and which risks you can safely take.

A real example

The situation

Two friends each earn a similar amount over a year. Kaveh is salaried; Bea is a freelance designer paid per project.

What happened

Kaveh can plan every month with confidence. Bea earns a lot in some months and almost nothing in others, so she keeps a larger buffer and pays herself a steady amount from it.

The takeaway

The same yearly income needs very different handling depending on its form.

How people actually behave

People tend to remember income as their gross figure or their best month, and budget as if every month will match it. That mismatch between remembered income and actual take-home pay is a quiet cause of overspending.

Common mistakes

• Budgeting from gross income instead of what actually arrives.
• Treating a strong month of variable income as the normal level.
• Ignoring the costs that come with some forms of income, such as tools, travel or taxes for freelancers.

Questions to think about

• Which forms of income do you have, and how predictable is each?
• Do you know your net income for a typical month, as a number?

Try it: Know your real income

1. Write down every source of income you had in the last three months.
2. For each, note the amount that actually reached you, not the gross figure.
3. Use the lowest of the three months as a cautious base for planning.
