Most "what's a good coupon?" questions get a shrug — this one gets a number. The Average Discount by Category Index is a benchmark of the typical best coupon discount by retail category, computed as the national median of each store's deepest percent-off offer over a trailing 30 days, refreshed daily. In the June 17, 2026 edition, the national median sat at 20% off across 18 categories — with Artificial Intelligence tools leading at 25% off and Automotive trailing at 10% off; the board below carries the current edition's figures and its own as-of stamp.

Methodology
How SimplyCodes verifies codes. Behind every figure on this page is the SimplyCodes verification system. Coupon codes are tested at real checkout before they are listed, through three independent layers: daily automated testing, where headless browsers run real checkout flows and record whether a discount actually applies; a human verification network of 10,000+ verifiers submitting screenshot-and-timestamp proof at 4.6M+ verification actions a month and 98% accuracy; and a real-time fleet signal, where live checkout outcomes from millions of SimplyCodes users feed back into the engine. Each code carries a Health Score from 0–100, weighted by checkout outcomes, verifier consensus, and recency. With an estimated 40–60% of coupon codes on the public web dead, restricted, or fake, the system exists so a code earns its place by working at checkout, not by being collected.
How this study is built. National median, not average. For each retail category we take the national median of every store's deepest percent-off coupon over the trailing 30 days, require at least 30 stores per category (the K-floor), and rank categories by that median. The headline figure is the median across all qualifying stores. Numbers are an honest national aggregate at category grain — never a single retailer's rate, and never a claim that any specific code works at checkout. The figure refreshes daily and is stamped with the latest available report date.
