What is the 50 30 20 rule?

The 50 30 20 rule is a handy rule of thumb for breaking down your monthly income into the following categories:

  • 50% of your money goes on your â€˜needs’.
  • 30% goes on your â€˜wants’.
  • 20% goes on your â€˜savings’.

Like most money matters, you might want to be flexible with the percentages in case of a shock bill or other unexpected expense. But the 50 30 20 budget can be a useful guide for thinking about how you spend and save.

How to use the 50 30 20 rule

Look at your monthly outgoings and divide them into the three categories of needs, wants and savings, to see how much you’re spending in each.

Needs

These are the things you simply need your money to go towards – the everyday living expenses that you can’t manage without. Your needs might include:

  • Mortgage/rent
  • Utility bills
  • Basic food shopping
  • Commuting costs or car payments
  • Insurance
  • Minimum repayments on credit cards or loans

Wants

Wants are the things that you choose to pay for but wouldn’t struggle to lose if you had to tighten your belt. Wants can include:

  • Days out
  • Restaurant trips
  • Subscriptions
  • Non-essential groceries 
  • Gigs and shows
  • Holidays

Savings

The remaining 20% goes on savings and debt repayments. This can include putting money aside as an emergency fund or into investments.

Paying extra on credit cards and personal loans also falls into this category. Doing this means you’ll be paying less on them in the future, saving you money in the long run. You can even make an overpayment on your mortgage – talk to your provider about what this involves and if it includes extra fees.

What does your 50 30 20 budget breakdown look like?

If your monthly income is £1,000 after tax, this is how it would break down when you apply the 50 30 20 rule:

  • £500 on needs
  • £300 on wants
  • £200 on savings.

You can use the table to see what the 50 30 20 rule might look like with different monthly take-home pay amounts.

    When you divide your monthly funds this way, you might be able to spot patterns in your current spending that are stopping you from saving money.

    You can use past bank statements to see whether you’re spending more on your needs or wants. Then you can decide what costs you can shift or reduce to be more in line with the 50 30 20 rule.

    Perhaps higher bills are taking you over the 50% need mark, so you need to adapt your savings goals for the time being. Or you’re overspending on wants, such as monthly subscriptions, when you can make do without.

How much of your salary should you save?

If you follow the 50 30 20 rule, you should aim to put 20% of your after-tax salary towards your savings goals.

If the unexpected should happen, your savings can come in handy. A boiler breakdown or car repair can cause major disruption. Making regular contributions to your savings should mean you’ll have the money needed to solve such issues.

It can also help to have a few months’ rent or mortgage payments saved, to give extra security in case of emergency.

Keeping track of your 50 30 20 budget

Sticking to the 50 30 20 plan can be difficult when budgeting gets tight and bills start to soar. If you don’t manage to split up your income exactly, don’t worry about it. The trick is to do what works for you while keeping your longer-term money goals in mind.

Here are a few ideas to help you keep track of your money, and to make it easier to keep to a 50 30 20 budget.

  • Make a habit of saving. Try to  put some of that 20% away for a rainy day each month, especially if you’ve skipped a month or two.
  • Keep records. Make a note of where your money’s going each month, whether it’s towards savings or on debt repayment, so you have a good idea of your current savings situation.
  • Use online tools. Get help managing your money with the Budget Calculator, or see where your money goes each month with Spending Insights.
  • Keep an eye on expenses. If bills are due to rise try to balance things out elsewhere in your budget so you aren’t caught out.
  • Don’t be too hard on yourself. If something comes up that means you can’t put money away this month, don’t worry about it. Certain times of the year are tough on saving, like Christmas or the school holidays.
  • Adjust the figures. Even after a hard look at your finances, it might not be possible to put 20% away each month. But 50 30 20 isn’t a hard and fast rule - just something to make you think about your finances. Whatever you can save every month, if it’s 10% or even 5%, the important thing is to try to stick with it.
