A commitment contract turns:
“I plan to do this.”
into:
“There will be a consequence if I don't.”
Three products worth considering are FailTax, stickK, and Beeminder.
| App | Best For | Core Mechanism |
|---|---|---|
| FailTax | Challenge-based accountability | Money behind a challenge |
| stickK | Traditional commitment contracts | Commitment + optional stakes and people |
| Beeminder | Quantified commitments | Stay on a measurable path or pay |
What is a commitment contract?
A commitment contract is an agreement you make in advance that changes the consequences of a future decision.
Imagine you genuinely want to work out tomorrow.
Tomorrow arrives.
Suddenly the couch sounds much better.
A commitment device changes that decision by creating a consequence today that your future self will have to consider tomorrow.
Financial stakes are one version of this idea. Social accountability, deadlines, deposits, and public commitments can work similarly.
1. FailTax — Best for challenge-based commitment
FailTax turns commitment into a challenge with real stakes.
Create a supported challenge, decide what success means, put money on the line, and commit.
Instead of simply hoping your future self stays motivated, you've changed the consequences of quitting.
Best for
People who want a simple challenge-based approach to accountability.
What makes it different?
The financial consequence is central to the experience rather than being another reminder or badge inside a habit tracker.
Ready to turn a plan into a commitment? Set a FailTax, choose your challenge, and put a real consequence behind following through.
Set Your 1st FailTax2. stickK — Best for traditional Commitment Contracts
stickK explicitly builds its product around Commitment Contracts.
Users define a goal and can add financial stakes, supporters, and a referee.
This makes it one of the clearest examples of the traditional commitment-contract concept.
Best for
People who want to formalize a goal and potentially bring other people into the accountability process.
3. Beeminder — Best for measurable commitments
Beeminder works particularly well when a commitment can be represented with data.
You define a measurable target, track your progress, and commit to remaining on the required trajectory.
Go off course and a financial consequence can apply.
Best for
People who enjoy quantifying their goals and continuously measuring progress.
Which commitment contract app should you choose?
Choose FailTax if your mental model is:
“I'm taking this challenge and putting money behind it.”
Choose stickK if it's:
“I'm formally committing to this goal and choosing how I'm held accountable.”
Choose Beeminder if it's:
“I'm keeping this measurable metric on track.”
The mechanism matters more than the label.
Choose the one that makes abandoning your particular goal meaningfully harder.

- Are commitment contracts the same as habit trackers?
- No. A habit tracker primarily records behavior. A commitment contract changes the consequences of future behavior.
- Can commitment contracts involve money?
- Yes. Financial stakes are one type of commitment device, but social accountability and other consequences can also be used.
- Does more money create a stronger commitment?
- Not automatically. The consequence should matter without creating financial distress.
- What kinds of goals work best?
- Goals with a clear definition of success are easier to hold yourself accountable to than vague goals like “be better” or “get healthier.”
