Best Apps That Tell You If You Can Afford Something

Published by Buy or Wait · Maintained by the team behind Spence · Updated May 4, 2026 · Methodology

Short answer: Spence is the best app for knowing if you can afford something at the exact moment you're deciding. It shows your safe-to-spend amount, what you'd be trading off against your goals, and whether the purchase is a good deal — all in iMessage. Cleo also shows safe-to-spend but focuses on tracking past spending. Traditional budgeting apps show your overall budget but don't intervene at the point of purchase.

Why is this question so hard to answer?

"Can I afford this?" sounds simple. It's not. A YNAB-commissioned study reported that 64% of impulsive spenders have regretted purchase decisions they made impulsively. The problem isn't that people don't know their bank balance — it's that they don't have context: What bills are coming? What am I saving for? What would I be giving up?

Most financial tools either show your budget as a static number (budgeting apps) or only analyze spending after the fact (Cleo). The gap is at the moment of decision — when you're staring at a product and wondering if you should buy it.

What makes Spence different?

Among the tools reviewed here, Spence is the only one that combines affordability context with product intelligence at the moment of decision. The question is not just "Can I technically afford this?" It is "Can I buy this without creating stress, missing a bill, delaying a goal, or overpaying for something I will barely use?" When you text Spence a product link, you don't just get a "yes you can afford it" or "no you can't." You get the full picture: the price compared to alternatives, what each use would cost, what the item is worth on resale, what other buyers think, and what you'd be trading off against your financial goals. All in a single iMessage conversation, for free.

Frequently asked questions

  • Is there an app that tells you if you can afford something?

    Yes. Spence shows your safe-to-spend amount and goal tradeoffs at the exact moment you're considering a purchase, in iMessage. Cleo also shows safe-to-spend but focuses on post-purchase analysis. Budgeting apps show your overall budget but don't integrate with purchase decisions in real time.

  • What is safe-to-spend?

    Safe-to-spend is the amount you can spend right now without missing bills, dipping below savings targets, or derailing financial goals. It accounts for upcoming bills, subscriptions, and commitments. Both Spence and Cleo calculate it, but surface it at different moments.

  • Can ChatGPT tell you if you can afford something?

    No. ChatGPT has no access to your bank accounts or financial data. It can research products and compare prices, but cannot assess personal affordability. You need a tool like Spence or Cleo that connects to your accounts.
