💡

专业提示

Use the would-I-buy-this-if-it-were-not-on-sale test. Sales create artificial urgency - if the answer is no, the discount is completely irrelevant. For best results with the Impulse Spending Calculator, always cross-verify your inputs against source data before calculating. Running the calculation with slightly varied inputs (sensitivity analysis) helps you understand which parameters have the greatest influence on the output and where measurement precision matters most.

难度:中级

你知道吗?

Studies show the mere presence of a credit card increases spending by 12-18% compared to paying in cash - contactless payment removes even more psychological friction.
