Envelope budgeting is the oldest budgeting method that still works. You decide what each pound or euro is for before you spend it, put it somewhere specific, and when an envelope is empty, you’re done spending on that thing.
Spendly gives you the method without the physical cash, and in any of 49 currencies.
How Envelopes Work in Spendly
You create envelopes for the things you spend on (Groceries, Eating Out, Transport, Kids’ Stuff) and allocate an amount to each. As you spend, the envelope drains. What’s left in the envelope is what’s left to spend.
- Named envelopes with whatever amount you allocate
- Priority ordering: drag envelopes into the order that matters, so the ones that must be funded sit at the top
- Per-currency: each envelope holds one currency, so an expat can run a euro grocery envelope and a sterling savings envelope side by side
- No pretend maths: an envelope shows what’s in it, not a projection of what might be
Why the Order Matters
Most envelope tools treat every envelope as equal. In practice they aren’t.
Rent, childcare and insurance have to be funded before anything else. Eating out doesn’t. When money is tight, the question is never “what does my budget say”: it’s “what gets funded first”. Spendly lets you drag envelopes into priority order so that question is already answered on a bad month.
Fund from the top down. Whatever runs out, runs out at the bottom, where it should.
Envelopes vs Category Budgets
Spendly has both, and they suit different people. The difference is subtle but it changes how the month feels.
| Envelopes | Category budgets | |
|---|---|---|
| The question it answers | “What’s left in this envelope?” | “Am I on track for the month?” |
| How it feels | Concrete. The money is either there or it isn’t | Analytical. You’re watching a rate against a limit |
| Handles a windfall | You allocate it somewhere specific | It just raises the number |
| Best for | People who overspend and need a hard stop | People who want visibility, not restriction |
You don’t have to choose. Plenty of people run category budgets for the whole month and envelopes for the two or three categories that actually cause problems.
Who Envelope Budgeting Suits
It works well if you tend to spend what’s available, if you’ve tried percentage budgets and found them too abstract, or if you need a concrete answer to “can we afford this”.
If your income is irregular, envelopes work best alongside sinking funds and the cash flow forecast. Those handle the variability, envelopes handle the day to day.
Envelopes Across Currencies
Each envelope holds one currency, so a euro grocery envelope stays a euro grocery envelope whatever the exchange rate does. This is where a digital envelope beats a paper one. If you’re paid in dollars and live in euros, a single envelope amount is meaningless: the number moves under you.
Spendly holds each envelope in its own currency, so a €400 grocery envelope stays a €400 grocery envelope regardless of what the dollar did this week. Your overall picture converts to your base currency at daily rates, so you can still see the total without the individual envelopes lying to you.

If you came here from YNAB, its envelope-style method is excellent but tied to one currency per budget.
Common questions
What is the difference between envelopes and category budgets?
An envelope answers “what is left in this envelope”, and a category budget answers “am I on track for the month”. Envelopes are concrete and give a hard stop. Budgets are analytical and give visibility. Spendly has both, and many people run budgets overall plus envelopes on the two or three categories that cause problems.
Can an envelope hold a currency other than my base currency?
Yes. Each envelope holds one currency, so a 400 euro grocery envelope stays 400 euros regardless of exchange rate movement. That matters because an envelope that silently resizes with the rate is no longer a limit, which was the point of having one.
What is envelope priority ordering?
You drag envelopes into the order that matters, so the ones that must be funded sit at the top. Rent, childcare and insurance get funded before eating out. On a tight month the question of what gets funded first is already answered, and whatever runs out runs out at the bottom.
