Nationwide, the world's largest building society with over 16 million members, has introduced a simple budgeting strategy known as the '50-30-20 rule' to help individuals save money. The approach requires a clear understanding of your income and spending habits, and the experts recommend starting with a budget plan.
Understanding the 50-30-20 Rule
The concept involves dividing your monthly after-tax income into three categories: 50% for necessities, 30% for discretionary spending, and 20% for savings or debt repayment. This method provides a structured way to manage finances without sacrificing enjoyment entirely.
Breaking Down the Percentages
- 50% on Musts – Fixed outgoings and essential living expenses like rent or mortgage, utilities, insurance, and food.
- 30% on Wants – Day-to-day spending on things you enjoy, such as subscriptions, dining out, and hobbies.
- 20% on Savings or Debt – Paying more than the minimum on debts or contributing to savings accounts, ISAs, or investments.
For example, with a monthly income of £1,500 after tax, this would allocate £750 to needs, £450 to wants, and £300 to savings or debt. However, Nationwide notes that this is just a guideline; you can adjust the percentages to suit your personal situation.
Listing Your Outgoings
To adhere to the plan, it's essential to list all expenses, including occasional purchases like impulse buys or social spending. A practical tip is to review your bank statements from the past three months to identify spending patterns and one-off costs, making your budget more realistic.
Common Bills to Consider
- Rent or mortgage
- Water, gas, and electricity
- Childcare
- Car payments
- Council Tax
- Home and contents insurance
- Car insurance
- Phone bill
- Travel costs (commute or holidays)
- Petrol and basic toiletries
- Food and prescriptions
- Subscriptions (Netflix, Spotify, etc.)
- Dining out and personal treats
- Hobbies
- Debt payments
- Gym or cinema memberships
Long-Term Savings Goals
You might also consider saving for future needs like a home deposit, emergency fund, renovations, holidays, or birthdays. These can be incorporated into the 20% savings portion.
Do You Need to Give Up Your Daily Coffee?
If you're struggling, cutting back on treats like coffee or Netflix might help, but Nationwide advises against eliminating things that bring you joy. The key is balance: reduce spending in areas where you can comfortably cut back while keeping what makes you happy.
Spend Less in One Area
Nationwide suggests setting a goal to reduce spending in a specific category, such as eating out. This small challenge can help you stay engaged with your budget and track your spending, keeping you focused on the bigger financial picture.
