60 40 Budget Rule: A Straightforward Way to Balance Bills and Savings

Ever feel like your paycheck disappears before you’ve had a chance to save? The 60 40 budget rule can change that. It tells you to spend 60% of what you earn on living costs – rent, groceries, transport – and put the remaining 40% toward savings, debt pay‑down, or investments. No fancy spreadsheet, just a clear split that keeps you living now and planning for later.

How the 60 40 Split Works in Real Life

First, calculate your net monthly income – the amount left after taxes and any deductions. Multiply that figure by 0.60. That’s the money you’re allowed to allocate to essentials. Anything above that goes straight into your financial goals bucket. For example, if you bring home £3,000 a month, £1,800 covers rent, bills, food, and transport. The other £1,200 can go into an emergency fund, a retirement ISA, or extra mortgage payments.

What makes the 60 40 rule flexible is that you decide where the 40% lands. Want to clear student loans faster? Throw more at the debt. Saving for a house deposit? Funnel it into a high‑interest savings account. The rule adapts to your priorities without demanding a full‑on zero‑based budget.

Practical Steps to Start Using the Rule Today

1. Track your spending for a month. Use a banking app or a simple notebook to see where your money goes. This will show you if you’re already close to the 60 % mark or need to cut back.

2. Identify essential vs. discretionary costs. Rent, utilities, and groceries are essential. Streaming services, dining out, and impulse buys are discretionary – they’re the first place to trim if you’re over the 60 % limit.

3. Automate the 40%. Set up a standing order that moves the 40% straight into a savings or investment account the day after payday. Automation removes the temptation to spend what you intended to save.

4. Review quarterly. Life changes – a raise, a new baby, a move. Re‑run the 60 40 calculation every three months and adjust the percentages if needed.

5. Mix in other budgeting basics. If you like the 50 30 20 rule or zero‑based budgeting, you can blend them. For instance, keep 60 % for essentials, then split the 40 % into 30 % for long‑term savings and 10 % for fun.

Remember, the goal isn’t perfection; it’s progress. Even if you start at 70 % versus 30 %, you’re moving toward a healthier financial habit.

By using the 60 40 rule, you get a clear roadmap that protects your day‑to‑day life while forcing you to grow your savings. It’s a simple mental model that works whether you earn £1,500 or £10,000 a month. Try it for a couple of months and see how quickly the “extra” money adds up – you might be surprised at how fast an emergency fund or a mortgage overpayment can grow.
