Practical Tips
At £40k you start paying 20% tax on a meaningful amount. Pension contributions reduce this.
Consider overpaying your mortgage if you have one - even £100/month saves thousands in interest.
This is the salary where lifestyle inflation becomes a real risk. Keep your fixed costs low.
Max out employer pension matching - it is free money.
Build 3-6 months of expenses in an emergency fund before investing.
Use Revolut or similar for fee-free spending abroad on holidays.
