Gross income is your total earnings before any deductions. Net income (or 'take-home pay') is what's left after deductions — the amount that actually reaches your bank account.
Always budget using net income, not gross. A £35,000 salary (gross) translates to roughly £28,000 take-home (net) for most people — a difference of around £580 per month. Budgeting based on the gross figure is one of the most common financial planning mistakes. Our free monthly budget template works from net income.
