How Much Are You Actually Saving on This Deal?

About This Calculator

This discount calculator operates in three modes: Find Sale Price (original price + discount % → sale price), Find Discount % (original + sale price → discount percentage), and Find Original Price (sale price + discount % → implied original). Optional sales tax is applied to the sale price to show the true out-of-pocket cost. Deal score (0–100) is derived from discount depth: under 10% = 25, 10–19% = 45, 20–29% = 60, 30–39% = 75, 40–49% = 85, 50%+ = 95. All results update in real time across all inputs and mode changes.

The Breakdown tab renders a horizontal bar chart decomposing the original price into "you pay" (accent) and "you save" (emerald) segments (plus tax if entered), and a bar chart of dollar savings at six discount levels (10%–60%) with your deal highlighted and a `ReferenceLine` at your savings amount. The Comparison tab shows a stacked bar chart where sale price (accent) + savings (emerald) = original price at each discount level, plus a line chart of sale price declining as discount increases, and a comparison table with deal ratings. The Value tab shows a bar chart of cost-per-use at six usage frequencies plus a cost-per-use card grid.

Dynamic accent colours reflect deal quality: emerald (Exceptional ≥85), green (Great ≥75), indigo (Good ≥60), amber (Modest ≥45), grey (Minor). The mode selector buttons adopt the accent colour when active. Four insights adapt to discount depth (genuine deal analysis), tax situation, price legitimacy guidance, and cost-per-use calculation. Four score-tier-adaptive What To Do Next steps cover verification, stacking, price matching, and return policies for good deals; and waiting strategies, reverse-engineering, and price alerts for modest discounts.
