How to do a no-spend challenge (and what to do when you slip)
A no-spend challenge is a set stretch of time, often a week or a month, where you only spend on things your own rules allow. The rules are the whole challenge. This guide covers choosing a length, writing rules you can keep, what counts as a no-spend day, how to track it, and what to do on the day it goes wrong.
Pick a length you can finish
Longer is not better. A challenge you finish teaches you more than one you abandon on day nine. Common lengths:
- One no-spend day a week. A good first step if a month sounds impossible.
- One week. Long enough to notice your habits, short enough to plan every day of it.
- Thirty days, or a calendar month. The classic version, used for No Buy January and No Spend September.
- A low-buy year. Not a year of zero spending, but a year with a short list of categories you stop buying and limits on the rest.
Choose your month with care
Look at the calendar before you commit. A month with a holiday, a wedding, a move or a big birthday will fight you. Some people deliberately pick their most expensive bill month, because cutting extras then gives them room. NerdWallet's writer picks January and July for exactly that reason.
Then give the challenge a reason. "Spend less" is vague. "Have a buffer for the car" or "pay off the card" is something you can picture on the hard days.
Write rules you can keep
Write two short lists before day one: what is allowed and what is not. Be specific. "No unnecessary spending" means nothing at 9pm when you are tired; "no delivery apps" does.
Rules work better as limits than as bans for things you will not realistically give up. Moneywise suggests boundaries like eating out only at weekends or pausing clothing for 30 days rather than "never". A few examples:
- Allowed: rent, bills, groceries from a list, transport to work, medicine.
- Allowed: replacing something once it has run out.
- Allowed with a cap: social plans, up to an amount you set for the week.
- Not allowed: clothes, beauty, decor, gadgets, hobby supplies.
- Not allowed: takeaway coffee, delivery, impulse snacks, new subscriptions.
What counts as a no-spend day
A no-spend day is a day where you buy nothing outside your allowed list. Bills that leave your account automatically do not break it. Neither does something someone else pays for.
The harder question is the allowed purchase. If you buy groceries from your list, did you have a no-spend day? Strictly, you spent money. In practice, most people count it as keeping their rules, because the rules allowed it. A useful middle ground is to mark those days differently from true zero-spend days, so you can see both without either one feeling like a failure.
Set up before day one
A few small changes do more than willpower:
- Unsubscribe from shop emails and turn off shopping app notifications.
- Log out of shopping apps and remove saved cards from browsers.
- Use up what you have: plan meals around the cupboard and freezer for the first week.
- Plan free things for the first two weekends before they arrive.
- Tell one person, or join a check-in thread, so someone notices if you go quiet.
- Decide where the money you do not spend will go, and move it on payday.
During the challenge: log what you did not buy
When you want something you would normally buy, write down what it was and its price, then leave it. Fast Company describes participants keeping this list in their phone's notes app and reading it back at the end of the month. NerdWallet's "wishlist and wait" is the same idea: wait a month and see if you still want it.
Two things happen. The urge passes more often than you expect. And the list gives you a running total of things you chose not to buy, which is a more honest number than any estimate of "how much I saved".
When you slip
A slip is a purchase your rules did not allow. It is one day. It does not cancel the days before it, and it does not decide the days after it. Often the challenge ends not on the slip but on the next morning, when "I have already ruined it" turns into a weekend of spending.
So treat it as data. Write down what you bought, the price, and what was going on: tired, bored, payday, a friend's plan, an advert. Then ask one question. Was the rule wrong, or was the situation new? If the rule was unrealistic, change it for the rest of the challenge. If the situation was new, plan for it. Then start the next day as an ordinary day.
If you keep slipping in the same place, the challenge is telling you something. Make that one category a limit rather than a ban, or switch from no-spend to low-buy for the rest of the month. Finishing a gentler version is still finishing.
After the challenge
Read your list of things you did not buy. Cross out what you no longer want. Anything left is a considered purchase you can plan for, not a reward haul for the first day of next month. Moneywise points out that the payoff is the habits rather than one month's total, so keep the one or two rules that worked.
Tracking it
A paper calendar is a perfectly good tracker. If you want it on your phone, Skipped is a free Android app built for this: set your challenge length and rules, stamp each no-spend day, log a spend your rules allow as a half stamp that keeps your run going, and keep a receipt of things you did not buy with a total. Other spends are logged without judgement. It works offline, with no account and no bank link.
Questions
How long should a no-spend challenge be?
As long as you can finish. For a first attempt, a week or one no-spend day a week is a reasonable start. A month is the most common length, and some people move on to a low-buy year.
Do bills count as spending in a no-spend challenge?
No. Rent, utilities, insurance and minimum debt payments are essentials in almost every version. The challenge is about discretionary spending.
What should I do if I break my no-spend challenge?
Note what you bought and why, decide whether the rule or the situation was the problem, adjust if needed, and carry on the next day. One slip does not undo the other days.
Is a no-spend challenge the same as a no-buy challenge?
They are used almost interchangeably. No-spend often refers to days with no discretionary spending; no-buy often refers to a period where you stop buying certain things, such as clothes or beauty products.
Do I need an app for a no-spend challenge?
No. A printed calendar and a list on paper work. An app can help if you want the calendar, the list of things you skipped and a reminder in one place on your phone.
