# Envelope budgeting when you never carry cash

> Splitting money into envelopes is the oldest way of keeping a budget. It works because the limit is hard and visible. Here is how to move it onto a card without losing the part that matters.

Envelope budgeting is older than online banking and still one of the most
effective methods around. The rule fits in a sentence: **when you get paid you
split the money into envelopes labelled by category, and when an envelope runs
low you stop spending in that category.**

Its power has nothing to do with paper. It comes from the limit being
**visible before you cross it**, rather than a month later on a statement.

## Why it works at all

An ordinary budget tells you what you spent. An envelope tells you what you
have **left** — and it tells you while you are standing at the till. That is
the whole difference.

A bank account shows one number for everything. Seeing a thousand in there on
the twentieth of the month tells you nothing about whether that is a lot,
until you work out what still has to come out of it. An envelope answers that
instantly: there is fifty left for food, and ten days to go.

The second reason is less obvious. Envelopes **close the decision in advance**.
"I'll eat out less" requires a decision at every meal. An envelope requires one
decision at the start of the month and nothing but looking afterwards.

## The cash version and where it breaks

In the original, the envelopes are real. That has one advantage you cannot
fake: an empty envelope cannot be argued with. It also has three drawbacks,
which is why almost nobody does it that way now.

**It does not cover card payments.** Subscriptions, loan payments and
transfers do not come out of an envelope. You are left with a system that
covers half your spending.

**There is no history.** Three months later you cannot reconstruct what food
actually cost in March, because an envelope does not record — it only empties.

**Keeping cash at home has a price.** Not just the risk. Money outside an
account earns nothing at all, not even what a plain savings account pays.

## Moving it onto a card

The heart of the method is not cash. It is **a hard per-category limit and
being able to see what is left**. Both are available without a wallet full of
envelopes.

Start with the categories that genuinely get away from you: groceries, eating
out, entertainment, clothes, small purchases. Those are the ones that escape a
budget. Rent and loan payments do not need an envelope, because their size
does not depend on any decision you make during the month.

Give each one a monthly limit. Do not invent the number — **take the average
of the last three months and cut ten percent.** A limit detached from reality
breaks in week two and stops meaning anything after that.

In the [budget module](/help/budget) a category with a limit does exactly what
an envelope does: it shows the amount remaining, not the amount spent. The
spending chart has a running-total view with a line spreading the limit evenly
across the days of the month — a curve above that line means "I am spending
faster than the envelope allows", and you see it on the fifteenth rather than
on the last day.

## What breaks envelope budgeting

**Too many envelopes.** Twelve categories is not a budget, it is bookkeeping.
With five or six you can remember which one you are in. With twelve every
purchase needs a decision about where it belongs, and after a month you stop
recording anything.

**Borrowing between envelopes.** Once is fine. As a habit it stops the
boundaries being boundaries, and the system turns into one big envelope, which
is the thing you were escaping.

**An envelope for everything.** One-off spending — a trip, a renovation, a
wedding — does not fit a monthly envelope, because it spreads across months.
A deposit in March, flights in May, the trip in July. Forced into a monthly
limit it will blow through three of them, despite being one expense. That is
what [projects](/help/projects) are for: they gather spending around an
occasion rather than around a month.

## What to do with what is left

An envelope with something left at the end of the month raises a question:
roll it over, or reset it?

**Rolling over makes sense for irregular categories** — clothes, presents,
pharmacy. You do not buy shoes every month, so two lean months and one fat one
is the normal rhythm rather than a deviation.

**Resetting makes sense for repeating ones** — groceries, fuel,
entertainment. Rolling those over turns a saving into a loan against next
month, and after six months nobody knows what the limit actually is.

## Where to start

Do not start with twelve envelopes and limits calculated to the penny. Start
with **the three categories that get away from you most**, and with limits
based on what you have actually been spending. The first month is a
measurement, not an exam.

The second month is the one where the method starts working — because only
then do you know where to put the line so that it has a chance of holding.
