Practical Tips
The 50/30/20 rule was popularised by US Senator Elizabeth Warren. It works well as a starting framework.
If your needs exceed 50%, focus on reducing your biggest expense - usually housing.
The 20% savings includes pension contributions, debt overpayments, and emergency fund.
In expensive cities like London, you may need 60/20/20 or even 70/15/15. Adjust to reality.
Automate the split: set up standing orders on payday to separate accounts.
Once your emergency fund is full (3-6 months expenses), redirect to investing.
