Most of us decide if we can afford something by checking whether we have enough money in our account to cover it. That is not the same as actually being able to afford it. This calculator asks the real questions. Do you have an emergency fund? High-interest debt? Are you maxing your retirement match? Are you saving anything at all? A $2,000 purchase looks very different if you have $50,000 saved and no debt versus if you have $800 in checking and $15,000 on credit cards. Enter the purchase and your financial situation. Get an honest verdict.

Frequently Asked Questions
What does "risk-adjusted" affordability mean?
Standard affordability just asks whether the number fits in your budget. Risk-adjusted affordability asks whether the purchase makes sense given everything else going on in your financial life. A $2,000 vacation is very different if you have a solid emergency fund, no high-interest debt, and a stable job versus if you are floating a $10,000 credit card balance, have three months of savings, and work at a startup. The same dollar amount. Completely different risk profiles.
Why does the calculator ask about my emergency fund?
Your emergency fund is the foundation everything else sits on. If you buy something and then an unexpected expense hits, where does the money come from? If the answer is a credit card, then you did not actually afford the thing you bought. You borrowed money to afford it. The minimum target is 3 months of essential expenses. If your emergency fund is below that, spending discretionary money on anything other than building it up is a form of financial risk-taking whether it feels like it or not.
Why does high-interest debt matter so much?
Paying off a credit card at 24% APR is a guaranteed 24% return on that money. There is no investment on earth that reliably beats that. Every dollar you spend on a discretionary purchase while carrying high-interest credit card debt is a dollar you could have used to get a guaranteed 24% return by eliminating that debt. That is the actual opportunity cost. It does not mean you can never spend money. It means the hurdle rate for discretionary spending is very high when you are carrying expensive debt.
What if the calculator says no but I really want it?
Then you have a choice to make with full information, which is the whole point. The calculator is not your parent. It is not telling you what to do. It is showing you the actual financial picture so you can make an honest decision rather than a rationalized one. Plenty of reasonable people decide to buy things that are not optimal financially because life is not a spreadsheet. The goal is just to make sure the decision is conscious rather than convenient.
When should I just save up instead of buying now?
Almost always for anything over $500 that is not an emergency. The mental friction of waiting and saving is a feature, not a bug. It filters out impulse purchases, gives you time to comparison shop, and means you arrive at the purchase in a better financial position. The purchases people most regret are overwhelmingly the ones made quickly under some kind of urgency, real or manufactured. If you can wait three months to save up for it and you still want it, that is a much cleaner signal that worth buying.
How is the affordability score calculated?
The score evaluates five factors: whether the purchase is within your monthly surplus, whether your emergency fund is adequately funded, whether you carry high-interest debt, whether you are capturing your employer retirement match, and your job stability. Each factor is weighted based on its financial impact. High-interest debt and emergency fund coverage carry the most weight because they represent the most acute financial risk. Job stability adjusts the overall score because the same purchase is riskier when your income is less certain.
