Willpower is unreliable, but the fear of losing money is not. Putting real cash on the line — money you’ll lose if you skip your habit — taps into loss aversion, the well-documented tendency to work harder to avoid losing something than to gain something of equal value. That’s the whole idea behind a “commitment contract,” and it’s why apps built around this concept have found a real audience among people who’ve tried and failed with willpower alone.

This guide walks through exactly how to set up a money-stakes system for any habit: how to pick the right amount, where to send the money if you fail, which tools can automate it, and the common ways people undermine their own bet before it even starts.
Quick Answer
Pick a single, clearly measurable habit, set a stake that would genuinely sting to lose (not so much that you’ll quit the bet itself), choose a referee or verification method you can’t fake, and route the forfeited money somewhere you don’t want it to go — an anti-charity or a cause you dislike works better than a charity you like. Apps like stickK and Beeminder automate the tracking and charging so you don’t have to enforce it on your own honor system.
Set Up Your Commitment Contract Step by Step
Start by picking one habit and defining it in a way that’s binary or countable — ‘exercise for 20 minutes’ or ‘write 500 words,’ not ‘be healthier.’ Vague goals can’t be verified, and a stake with no clear pass/fail line just becomes a source of arguments with yourself.
Set the reporting frequency next. Daily check-ins work best for building a new routine because the stakes stay top of mind; weekly check-ins suit habits that naturally happen a few times a week, like gym sessions. Whatever you choose, keep the window short enough that failure is obvious quickly — a habit you only check on monthly gives you a month to talk yourself out of it.
Decide the stake amount so it hurts but doesn’t wreck your budget. stickK, for example, requires at least $5 per reporting period, so you can start small and raise the amount once you see whether the pressure actually changes your behavior. If a five- or ten-dollar loss doesn’t bother you, raise it until it does — that discomfort is the entire mechanism.
Choose where the money goes if you fail. Sending it to a friend, a charity you already support, or back into your own savings blunts the sting, because part of you is fine with any of those outcomes. Sending it to an ‘anti-charity’ — an organization whose mission you actively dislike — removes that escape hatch and is a core feature on stickK for this exact reason.
Line up a referee or verification method. Self-reporting is the weakest link in any stakes system, since it’s easy to quietly let yourself off the hook. A friend who confirms your gym check-ins or a habit-tracking app that pulls data automatically from your phone or wearable works better than an honor system.
Finally, put the contract in writing somewhere you’ll see it — in an app, a shared doc with your referee, or a note pinned to your desk. The act of writing down the terms, the amount, and the deadline makes the commitment feel real before you’ve even risked a dollar.
Tools That Automate Money-Stakes Habits
You don’t need to build this system by hand. stickK, co-founded by Yale economist Dean Karlan, lets you create a formal ‘commitment contract’ with a chosen stake, referee, and recipient for forfeited funds, and it’s free to set up — you’re only charged if you report failure with money on the line.
Beeminder takes a more data-driven approach: you set a numeric goal (workout minutes, pages written, weight, anything trackable), and the app plots your progress against a target line on a graph. Miss the line and it automatically charges your card — pledges start as low as $5 and climb at each subsequent derailment, up to a cap you set, so repeated slacking gets progressively more expensive.
If you’d rather skip an app entirely, a low-tech version works too: Venmo or PayPal a set amount to a friend in advance and have them send it to a cause you hate if you don’t check in by a deadline. The mechanism matters more than the platform — money at risk, a clear deadline, and someone besides you enforcing it.
Before trusting any newer habit-stakes app with your card, read its own terms or support page closely. Some apps market ‘financial stakes’ or ‘commitment contract’ language but actually run on symbolic stakes by default — you pick a leniency or honor-system setting, and no money moves unless you specifically opt into a real charge. Confirm whether the app you’re considering charges automatically on failure or only when you’ve explicitly turned on real money before assuming it works like stickK or Beeminder.
Tips and Common Mistakes
Don’t stack too many stakes at once. Betting money on five new habits simultaneously usually means all five collapse together once life gets busy — start with one habit, prove the system works for you, then add a second.
Avoid picking a stake amount that’s trivial to you. If losing the money doesn’t register emotionally, the whole mechanism does nothing; the discomfort of a potential loss is the actual behavior-change engine, not the money itself.
Don’t be your own referee for anything you’re tempted to fudge. If a habit is easy to fake (‘I definitely went to the gym’), build in outside verification from day one rather than waiting until you’ve already caught yourself cheating once.
Set an end date or a reassessment point. A stakes contract that runs forever with no review tends to either get abandoned quietly or become a source of resentment — plan to revisit the terms every few weeks and lower the stakes (or drop them) once the habit feels automatic.
Expect an early wobble. The first one to two weeks of any new habit are the hardest, and that’s exactly when a money stake earns its keep — it’s designed to carry you through the days motivation alone won’t.

Money stakes for habits FAQs
How much money should I stake on a habit?
Enough that losing it actually bothers you but not so much that missing a day feels catastrophic. Many people start around $5-$20 per lapse and adjust from there — if you don’t flinch at the amount, it’s too low to change your behavior.
What happens to the money if I fail?
It depends on the setup you choose. It can go to a friend, a charity you support, an anti-charity (a cause you dislike, which tends to work best), or simply be charged to your card by an app like Beeminder.
Do money-stakes apps actually work better than willpower alone?
The underlying idea comes from loss aversion — people are generally more motivated to avoid losing money than to gain an equivalent reward — which is why economists helped design tools like stickK specifically around this principle rather than relying on willpower or reminders alone.
Can I use a money-stakes system without an app?
Yes. Give a set amount of cash or a pre-written check to a friend or family member with instructions to send it somewhere you don’t want it to go if you miss your habit deadline. An app just automates tracking, charging, and verification.
What’s the difference between stickK and Beeminder?
stickK is built around formal commitment contracts with a referee and a chosen recipient for forfeited funds. Beeminder instead tracks a numeric goal against a graphed target line and auto-charges your card whenever you fall off the line, with the pledge amount increasing after each miss.
