The Economy Is Rigged Against You. But This One Simple Rule Still Works...


Bills are climbing. Inflation refuses to die. Interest rates aren’t dropping soon. UK stats show:

  • UK Inflation hasn't been below its target rate for 2 years.
  • Rents is averaging 40% of income.
  • Real wage growth is near zero.

Marketing, brands, and influencers have never been more persuasive at emptying your account.

The squeeze is real — and it’s exhausting. But here’s the truth: you don’t need a huge salary increase to feel relief. You need a better system.

One of the simplest and most effective is the 50/30/20 rule.

A practical framework for allocating your income so it finally starts working for you instead of everyone else.

What is the 50/30/20 Rule?

Popularised by Senator Elizabeth Warren in her book 'All Your Worth', it’s a balanced budgeting method:

  • 50% on Needs (essentials)
  • 30% on Wants (lifestyle)
  • 20% on Savings & Investments (future you)

It’s not perfect for every situation, but it’s easy to understand and incredibly effective when followed consistently.

Step-by-Step: How to Implement It This Month

1. Know Your Real Take-Home Look at your latest payslip. Use the exact amount that lands in your bank (after tax and deductions).

Example: £5,000 monthly take-home → £2,500 Needs | £1,500 Wants | £1,000 Future.

2. Audit Your Spending Review the last 3 months of transactions. Categorise everything honestly:

  • Needs: Rent/mortgage, utilities, groceries, transport, insurance, minimum debt payments.
  • Wants: Dining out, subscriptions, shopping, entertainment, holidays.
  • Savings/Investing: Everything you’re already putting away.

3. Adjust to the Target Ratio Compare your current split to 50/30/20.

  • If Needs are over 50% → Look for cuts (cheaper phone plan, energy switching, bulk buying, car share).
  • If Wants are over 30% → Be ruthless. Rank non-essentials and cut from the bottom until you hit ~30%.
  • If you’re investing less than 20% → The previous cuts usually create the breathing room.

4. Direct Your 20% Wisely Prioritise in this order:

  1. Emergency Fund – Build 3–6 months of essential expenses in an easy-access savings account.
  2. Investing – Put money into a tax-efficient account (ISA in the UK) and choose low-cost, diversified ETFs (e.g. global or S&P 500 trackers).
  3. Personal Development – Courses, books, coaching, or tools that help you earn more.

Power Move: Automate Set up standing orders for the day (or day after) you get paid. Pay yourself first, like wealthy people do.

Final Thought

We can’t control rising costs, taxes, or inflation. But we can control how we allocate every pound that comes in. The 50/30/20 rule won’t make you rich overnight, but consistent execution builds real freedom. Start this week:

  1. Check your last payslip
  2. Run your numbers
  3. Set up one auto-transfer for the 20%

I Had a Glimpse Into a Potential Future — and I Didn't Like What I Saw... Last weekend, we met some old friends for lunch. The conversation ebbed and flowed, and eventually turned to their parents. They're both in their early 60s — worked hard all their life, always earned comfortably, but always lived in the moment rather than planning ahead. As the conversation got deeper, we learned that our friend's grandfather had recently passed away. He was the one potential source of inheritance their...
