How to know if you can afford something
Whether you can afford something depends less on your balance today than on what's due before your next paychecks. Here's a quick way to check.
Written and checked by the Bill & Debt Snowball team. Every figure is worked out with the app's own payoff math. Last checked October 23, 2026. How we check
The check
- Start with what you have now, or your next paycheck if you live check to check.
- Subtract every bill and debt payment due before the paycheck after that.
- Subtract the purchase. If something is still left, it fits this time around.
- For a new monthly cost (a phone plan, a subscription), check that it fits every month, not just this one.
When the answer is "not yet"
Saving up for it is often the cheapest way to buy it. Divide the price by the months until you want it, and set that aside each month like a bill. Paying for it later on a credit card usually costs more because of interest.
Using your emergency fund for something you want, not something unexpected, leaves you without a cushion. If you do, plan to put it back. See how big an emergency fund should be.
