Step-by-Step Guide

Follow these steps to get the most from this tool

Start with gross income (before tax): Include all sources: employment salary, self-employment profit (average last 2-3 years), rental income, investment returns, pension drawdown. Lenders verify income, so be accurate. For couples, add both incomes.

List all monthly expenses: Food (£300-500), utilities (£150-250), transport (£100-300), insurance (£100-200), childcare (£0-2,000+), subscriptions (£50-100), entertainment. Total these honestly. Lenders look at this when determining your mortgage capacity.

Why this matters: Lenders subtract your expenses from income to calculate "disposable income" available for a mortgage. High expenses = lower borrowing power, even with high income. A £60k earner with £2,000/month expenses can borrow far less than one with £800/month expenses.

Cross-tool context: Use UK Budget Income Planner to understand exactly where your money goes. You'll surprise yourself—most people discover hidden expenses (£100-200/month) when tracking carefully.
