Cash envelope budgeting: which spending suits it and which does not

The envelope method is old and simple: take the cash for a spending category out at the start of the week or month, put it in an envelope, and stop spending in that category when the envelope is empty. It works because it makes the limit something you can see and handle. A bank balance is a number that moves without you noticing, while an envelope with £20 left in it is hard to ignore. This article covers which spending suits the method, how to set it up using the figures from the Cash Buddy budget tracker, and where it does not fit.

What the method does well

Most overspending is not on big items. It is on the categories where a small purchase happens often and nothing marks the total: food shopping top-ups, takeaways, coffee, small online and in-shop purchases. For those, cash has two effects. The amount is capped, and the cost is felt at the point of paying. Neither is true of a card tap.

It is a method for variable spending only. Rent, council tax, energy and anything else that has a fixed amount on a fixed date stays as it is, usually by direct debit or standing order, so the date is never missed. The envelopes cover what is left once those are paid.

Which categories suit envelopes

The tracker uses these headings for expenses: food, transport, bills, entertainment, shopping, healthcare and other. Not all of them belong in cash.

Suits envelopes: food shopping and top-ups, eating out and takeaways, entertainment, personal spending, clothes, and anything under the "shopping" heading you buy in a shop.
Does not suit envelopes: bills, which belong on a direct debit; transport costs that are a monthly pass; healthcare that is paid in a lump; anything bought online, where cash cannot be used.
In between: fuel and parking. They can go in cash if you pay at a pump or machine that takes it, and on a card otherwise.

Start with two or three envelopes, not ten, because each one is another thing to count and refill every week. The usual first ones are food, eating out and personal spending, because those are the categories where most people find the money goes without a record.

A worked example

These figures are an example only. Say your monthly take-home pay is £2,000 and the following leave your account by direct debit or standing order: rent, council tax, energy, broadband, phone and the other bills. Suppose that adds up to £1,300. You have £700 left for everything else.

Now allocate the £700 for a four-week period:

Food: £320, or £80 a week.
Eating out and takeaways: £100, or £25 a week.
Personal spending: £80, or £20 a week.
Transport top-ups and small costs: £120.
A buffer: £80, held back for the month, not spent in the first week.

That is £700 across five lines. Only the weekly envelopes (food, eating out and personal spending) are filled each week. The rest stays in the account until needed. If the week's envelope is empty by Thursday, the category is finished until the next week. If money is left, it either carries over or moves to the buffer, and you decide which before the month starts, not on the day.

The Cash Buddy tracker works alongside it. Enter each purchase under its category, set a monthly and a weekly budget in the settings, and it shows what has been spent against each, so the cash and the record can be compared at the end of each week. The budgets are single totals, so the split between envelopes stays on paper.

What you need

None of it requires buying anything: envelopes and a pen will do. A few items make it easier to keep going.

A Ad cash envelope wallet with labelled sections holds the categories in one place, so there is one thing to carry or leave at home.
A Ad zip cash envelope set lasts longer than paper if you use the method month after month.
A Ad budget notebook records the opening amount and what was spent each week, which the tracker can then match.
A Ad small cash tin with a lock keeps the envelopes you are not carrying, because cash at home needs to be kept out of sight.

Check the pockets are big enough for the notes you actually carry, because a wallet designed for coins will not hold a week's food money.

Where it falls short

Envelopes assume you can pay in cash, and that is not true of everything. Online purchases and subscriptions need a card or an account, and some places take cards only. If most of a category is paid that way, an envelope for it will sit full while the card account is used up. In that case, track the category in the tracker instead, and use an envelope only for the part you can pay in cash.

Cash also needs looking after. Keep the full amount at home in a place that is not obvious, and carry only the week's envelope. Lost cash is not recoverable, which is a reason to keep the amount in your wallet small.

Keep it honest with a weekly check

Once a week, on the same day, spend five minutes on three things:

Count what is in each envelope and enter the spend in the tracker.
Compare the total with the weekly limit you set.
Decide, before refilling, whether the limit was right. If the food envelope was empty by Wednesday three weeks in a row, the limit was too low, and the right move is to change the limit on paper, by moving money from another line in the budget, not by taking from next week's envelope.

If the numbers do not add up even with every line cut, that is the point to talk to someone. The Money and Pensions Service runs the free MoneyHelper budget planner, which breaks down income and spending by category. Citizens Advice is another place to ask about a budget that is not working.
