The months on this calendar are ranked by how deep treadmill promo codes actually run — the share of codes SimplyCodes verified in each month that took 25% off or deeper, pooled across every year on record and re-measured daily. It reads the discount climate across treadmill brands and the equipment sellers that carry the machines rather than the price of one model, since a brand store's code usually applies across its whole catalog.

Deep-discount share = the share of that month's treadmills and home cardio equipment stores whose deepest percentage-off code was 25% off or more · bar = that share relative to the strongest month · store-months = the denominator behind each share, one per store per month it ran a percentage-off code · — = fewer than 3 retailers contributed that month, so no share publishes · free ship / free gift = at least one such offer verified in that month.

Frequently asked questions
When is the best time to buy a treadmill?
The calendar above names the strongest month, its share of deep codes, and the date the snapshot was taken. Pooled across every year on record, the late-summer and early-autumn months carry the highest share of deep treadmill codes and the late-winter months carry the lowest, so a machine bought in February comes out of the year's thinnest code pool.
What month are treadmills cheapest?
Cheapest and deepest-discounted are not the same claim, and this study only makes the second one. It ranks months by the share of verified treadmill codes running 25% off or deeper across the brands and equipment sellers SimplyCodes tracks. A treadmill's shelf price also moves with model-year turnover, freight and floor-model clearance, none of which run through a promo code, so read the peak month as the widest code window rather than a guaranteed low price. The set behind it is NordicTrack, Peloton, Bowflex, ProForm, Sole Fitness, Horizon Fitness, Echelon Fitness, Schwinn Fitness, Life Fitness, Precor at Home, Xterra Fitness, TRUE Fitness, Matrix Fitness, Sunny Health & Fitness, Octane Fitness, Concept2, Hydrow, Rogue Fitness, Fitness Factory and Fitness Superstore, along with the rest of the equipment aisle.
Is January really the best month for treadmill deals?
January is the busy month for treadmill shopping, not the deep one. On the calendar above the resolution months sit near the bottom of the ranking, and the strongest months land in late summer and early autumn, when new model years arrive and the prior season's machines move to clearance. The ranking pools every year on record, so treat it as the pattern the market has repeated rather than a forecast for one particular January.
Does a deep treadmill discount mean the code will work at checkout?
They are separate questions. Depth is how much a code takes off, and reliability is whether it still applies at checkout — the Health Score (SimplyCodes' 0-100 measure of how likely a code is to work at checkout, built from live checkout tests, verifier consensus, and recency) on each code covers the second one. This calendar reads depth only, and each brand's or seller's own SimplyCodes page carries its current working codes.
Methodology
How SimplyCodes verifies codes. Behind every figure in this live data study 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 runs headless browsers through real checkout flows and records whether a discount actually applies. A human verification network of 10,000+ verifiers submits screenshot-and-timestamp proof. And a real-time fleet signal, where live checkout outcomes feed back into the engine. The calendar below summarizes that verification history month by month.
How this calendar is built. we take every treadmills and home cardio equipment store SimplyCodes tracks at the treadmill brands and home fitness equipment retailers SimplyCodes tracks and record, for each calendar month that store ran a percentage-off code, the deepest discount it offered that month — so "September" means every September on record, not one year's. For each month we report the share of those stores whose deepest code reached 25% off or more, alongside the number of store-months behind the share. This measures how many stores discount deeply in a given month, not how many individual codes did. Only percentage-off codes are counted, because fixed-amount offers are not comparable across price points. Percentage claims of 95% or more are excluded as implausible. And a month contributed by fewer than 3 retailers publishes no share at all
