Build a purchase planning application that helps users decide whether to buy an item now, wait, choose an alternative, or avoid the purchase.
Users enter the item, current price, budget, urgency, expected useful life, available alternatives, and any verified historical price observations.
The application should:
Separate essential purchases from discretionary purchases.
Calculate the effect of the purchase on the user's available budget.
Compare alternatives using total ownership cost, expected durability, maintenance, and replacement costs.
Model the financial impact of waiting for configurable periods.
Evaluate hypothetical discounts without assuming that a future discount will occur.
Identify recurring purchases that may create cumulative budget pressure.
Record the original reason for buying and compare it with the eventual outcome.
Generate a transparent recommendation based on user-defined priorities.
Include a purchase comparison table, scenario controls, budget impact visualization, and exportable decision history.
Do not invent current prices or predict future prices as certainties. Clearly separate user-provided information, verified observations, and hypothetical assumptions. Avoid pressuring users to purchase through artificial urgency or unsupported savings claims.
