How to Use This Calculator

Enter the cost of the purchase you're considering and your monthly income.
Rate the necessity of the item (1 = pure want, 10 = essential need) and how frequently you'd use it.
Rate whether alternatives exist and your current emotional state (1 = stressed/emotional, 10 = calm/rational).
Review Needs Score and Classification (Need, Want, or Impulse) for an objective assessment.
Check Waiting Period Hours — if the item is flagged as a potential impulse buy, wait that many hours before purchasing.

Impulse risk flag (0/1): 1 = high risk of impulse purchase (emotional state + low need score).

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Purchase cost ($) = 200, Monthly income ($) = 5000, How necessary? (1-10) = 5, Expected use frequency (1-10) = 5 = 6 input(s) provided
Calculate Needs score
Needs score
53 = 53
Calculate Classification
3 = 3
Calculate Cost as % of monthly income
Cost as % of monthly income = (purchaseCost / monthlyIncome) * 100
4 = 4%
