Fixed vs variable costs

Why high fixed costs make you fragile when income drops.

In the app: 2 lessons · 1 quick check

Key points

1. Two kinds of expense

  • Fixed — the same every month whatever you earn: rent, school fees, loan repayments.
  • Variable — changes with your choices: food out, transport, data, clothes.

2. Stay flexible

  • Before taking on a new fixed cost — a bigger flat, a car loan — ask whether you could still pay it in your worst month. Mark each expense as fixed or variable in Wealth Builder…

Lower fixed costs plus an emergency fund = less fear when business slows down.
