In March 2026, Etsy quietly rewired the number under every shop’s name. For years, your displayed star rating was an average of only your last 12 months of reviews — a shop’s entire lifetime of feedback existed on the reviews page, but the score at the top only reflected the most recent year. Etsy has now switched to a lifetime calculation where every review you’ve ever received counts, but its influence decreases by half every year it ages (Etsy Seller Handbook, “We’re Updating How Average Review Ratings Are Calculated”). That single mechanical change can move a shop’s displayed rating by several tenths of a star in either direction, without a single new review being left. This piece works through exactly how the new formula behaves, with two worked examples showing the actual math.

Introduction
Every Etsy shop has always had two review numbers sitting next to each other, and most sellers never noticed they weren’t measuring the same thing. The review count — “1,204 reviews” — has always been a lifetime figure, every review the shop has ever collected, going back to the day it opened. The star rating next to it, though, was calculated on a rolling 12-month window: only reviews left in the past year fed the average, even though buyers were looking at a total that included years more history than that. A shop with nine excellent years and one rough one could watch its displayed rating crater based entirely on that single bad year, while the “1,204 reviews” beside it quietly implied a much longer, steadier track record buyers had no way to actually see reflected in the star number.
On March 13, 2026, Etsy published a seller handbook article announcing it was retiring that 12-month window in favor of a lifetime calculation, updating the article again on March 25 with additional detail after seller questions (Etsy Seller Handbook). Under the new system, every review a shop has ever received counts toward its rating — but not equally. Etsy’s own description of the mechanic is that “newer reviews count more, and the impact of each review decreases by half each year” it ages. That’s a specific, modelable claim, and this piece models it: what the old system rewarded and punished, what the new one does instead, and two worked examples showing shops whose displayed rating moves by several tenths of a star purely from this formula change, with zero new reviews involved.
What Actually Changed: 12-Month Window vs. Lifetime Weighting
The old system was a hard cutoff. A review left 11 months ago counted in full. A review left 13 months ago counted for nothing — it still showed up if a buyer scrolled through the full reviews list, but it contributed zero weight to the star average at the top of the shop. This produced two specific, well-documented distortions:
- A single bad stretch could dominate the entire visible score. A shop that shipped late for three months because of a carrier problem, a supplier shortage, or a seller’s own medical leave would see its rating swing hard on whatever fraction of the last 12 months that stretch represented — even if the shop had operated flawlessly for years before and fixed the problem months ago.
- Shops that went quiet came back to a blank slate, in the worst way. A seller who paused for 13+ months — a parental leave, a move, a burnout break — would return to find their star rating showing as unrated or artificially low, because there were no reviews inside the trailing 12-month window to average at all, regardless of how strong the shop’s history was.
The new system removes the hard cutoff entirely. Instead of a window that reviews either fall inside or outside of, every review gets a weight that shrinks continuously with age. Etsy’s own stated rule is that a review’s impact “decreases by half each year.” Combined with counting the full lifetime of reviews rather than the last 12 months, that means a rating is now much harder to crater from one bad quarter, but also much harder to fully outrun with one great quarter — older issues fade, they don’t vanish, and they definitely don’t disappear the moment they cross a 365-day line the way they used to.
One thing the change does not touch: the raw review text, star-by-star breakdowns, and photo/video content buyers see when they actually open a shop’s reviews page. Nothing about individual reviews changes. What changes is purely the arithmetic behind the single number displayed next to a shop’s name.
The Half-Life Mechanic, Modeled
Etsy hasn’t published the exact formula down to the decimal, and there’s no reason to expect they will — algorithmic specifics that sellers could game usually stay undisclosed. But “decreases by half each year” is precise enough to model as a simple half-life: a review’s weight in year 0 (the most recent 12 months) counts as a full 1.0, a review that’s 1–2 years old counts as roughly 0.5, one that’s 2–3 years old counts as roughly 0.25, one that’s 3–4 years old counts as roughly 0.125, and so on, halving with each additional year.
Two caveats worth stating plainly before the worked examples: first, this is an illustrative model built directly from Etsy’s own public description of the mechanic, not a reverse-engineered exact formula — Etsy may weight continuously by day rather than in whole-year buckets, and the real decay constant may not land exactly on “50% per year.” Second, no seller needs to actually run this math day-to-day. The useful takeaway isn’t the formula, it’s the shape of the effect: recent reviews dominate, older reviews fade but never zero out, and the practical result is a rating that moves more slowly and more smoothly than the old 12-month cliff-edge version did.
Worked Example 1: A Shop Climbing Out of a Rough Patch
Take a five-year-old shop that had genuinely excellent service for four years, then hit a bad stretch in the most recent 12 months because its regional shipping carrier started missing delivery windows all winter. The review history, bucketed by age:
- 0–1 year old (the carrier-delay stretch): 25 reviews, averaging 3.8 stars
- 1–2 years old: 35 reviews, averaging 4.9 stars
- 2–3 years old: 40 reviews, averaging 4.95 stars
- 3–4 years old: 30 reviews, averaging 4.9 stars
- 4–5 years old: 20 reviews, averaging 4.85 stars
Under the old 12-month-only method: only the first bucket counts. The displayed rating is a flat 3.80 — a shop with four years of near-perfect service looks, at a glance, like a shop having ongoing quality problems.
Under the new lifetime-weighted method, applying the half-per-year weights (1.0, 0.5, 0.25, 0.125, 0.0625) to each bucket:
| Age bucket | Reviews | Avg. stars | Weight | Weighted stars | Weighted count |
|---|---|---|---|---|---|
| 0–1 yr | 25 | 3.80 | 1.000 | 95.00 | 25.00 |
| 1–2 yr | 35 | 4.90 | 0.500 | 85.75 | 17.50 |
| 2–3 yr | 40 | 4.95 | 0.250 | 49.50 | 10.00 |
| 3–4 yr | 30 | 4.90 | 0.125 | 18.38 | 3.75 |
| 4–5 yr | 20 | 4.85 | 0.0625 | 6.06 | 1.25 |
| Total | 150 | – | – | 254.69 | 57.50 |
254.69 ÷ 57.50 = 4.43 stars. That’s the new displayed rating — a full 0.63 stars higher than what the old method showed, for the exact same set of reviews. The shop’s current, ongoing shipping problem still drags the score down from where it was before the bad stretch (its 1–4-year average alone would be roughly 4.9), which is honest — buyers shopping today should see some effect from a real, current issue. But it’s no longer the only thing determining the number, the way it was under the 12-month cutoff.
Worked Example 2: A Shop That Already Healed, Still Paying For It
Now the mirror case: a shop that had a real quality-control problem 1–2 years ago — a batch of a popular item shipped with a manufacturing defect — fixed it, and has been performing excellently for the past year:
- 0–1 year old (post-fix, current): 50 reviews, averaging 4.95 stars
- 1–2 years old (the defective batch): 20 reviews, averaging 2.90 stars
- 2–3 years old: 15 reviews, averaging 4.80 stars
- 3–4 years old: 10 reviews, averaging 4.90 stars
Under the old method: only the most recent 12 months count, and this shop looks fully recovered — a clean 4.95.
Under the new method:
| Age bucket | Reviews | Avg. stars | Weight | Weighted stars | Weighted count |
|---|---|---|---|---|---|
| 0–1 yr | 50 | 4.95 | 1.000 | 247.50 | 50.00 |
| 1–2 yr | 20 | 2.90 | 0.500 | 29.00 | 10.00 |
| 2–3 yr | 15 | 4.80 | 0.250 | 18.00 | 3.75 |
| 3–4 yr | 10 | 4.90 | 0.125 | 6.13 | 1.25 |
| Total | 95 | – | – | 300.63 | 65.00 |
300.63 ÷ 65.00 = 4.63 stars — about 0.32 stars lower than the 4.95 the old method would have shown, even though the shop’s current performance is objectively excellent and the defect is a year-plus in the past. This is the trade-off inherent in any recency-weighted lifetime average: a bad patch you’ve genuinely fixed still costs you something for a while, because “decreases by half each year” means that patch is still carrying 50% weight at the one-year mark, not zero. It keeps fading every month after that, but it doesn’t vanish on a fixed schedule the way the old 365-day cutoff let it.
What Didn’t Change: Star Seller’s 3-Month Window
It’s worth being precise about scope, because it’s easy to assume a review-rating overhaul touches everything review-adjacent. It doesn’t. The Star Seller badge evaluation — message response rate, on-time shipping and tracking, and review average — continues to run on its existing rolling window looking at recent performance (Etsy’s guidance points to the trailing few months, not a lifetime figure), separate from this change to the shop-level star rating shown to buyers. A shop can see its public-facing star rating shift under the new lifetime formula while its Star Seller eligibility keeps being judged on an entirely separate, shorter-term calculation. The two systems answer different questions — “how good is this shop, overall, ever” versus “is this shop currently operating well” — and Etsy is keeping them mechanically distinct rather than merging them into one number.
Why Etsy Made This Change
Etsy’s own framing centers on the mismatch described above: a lifetime review count sitting next to a 12-month rating was, functionally, showing buyers two different denominators without saying so. A shop with “2,400 reviews · 4.2 stars” implied the 4.2 was an average of 2,400 data points; it was actually an average of whatever fraction of those fell in the last year, which buyers had no way to know without digging into the reviews page themselves. Moving to a lifetime-weighted calculation makes the two numbers describe the same underlying population, just with recent experience counted more heavily — closer to how rating systems work on other major marketplaces, where long-term history contributes to a seller’s score but doesn’t get to outweigh how they’re performing right now.
It also directly addresses the returning-seller problem: a shop that stepped away for over a year no longer resets to an unrated or artificially depressed score the moment its 12-month window empties out. Its history keeps contributing, just at a discounted weight that grows lighter the longer the gap runs.
What This Means for a New Shop vs. an Established One
The practical effect splits cleanly along shop age:
- Shops under a year old see essentially no change. With no reviews old enough to fall into a discounted bucket, the weighted lifetime average and the old 12-month average are close to identical — every review a brand-new shop has is, by definition, inside year zero.
- Shops with a rocky start that have since improved benefit the most, and increasingly so as the shop ages. An early stretch of learning-curve mistakes — slow shipping before a seller nailed their workflow, a few disappointed buyers before packaging got dialed in — keeps losing weight every year it recedes into the past, eventually becoming close to negligible rather than disappearing on a hard 365-day cutoff.
- Shops with a strong multi-year history and one recent bad quarter are the clearest winners, as Worked Example 1 shows — years of good history now visibly cushion a temporary problem instead of being invisible to the rating entirely.
- Shops with a real problem in roughly the last 1–2 years are the clearest group seeing a rating decrease, as in Worked Example 2 — recent-but-not-current issues that used to age out cleanly at the 12-month mark now keep costing real weight for another year or more.
What Sellers Can Actually Do About It
There’s no lever to pull on the formula itself, but there are a handful of concrete, correct responses:
Misconceptions Sellers Are Getting Wrong About This
A few claims circulating in seller forums since the March announcement are worth correcting directly:
- “Old reviews now count the same as new ones.” The opposite is true — recency weighting means new reviews matter substantially more than old ones. The change is that old reviews now count at all past 12 months, not that they count equally.
- “This changes Star Seller eligibility.” It doesn’t. Star Seller’s review-average component looks at a separate, recent window, unaffected by this update to the shop’s public star rating.
- “I can get my rating back to where it was by requesting my old bad reviews be removed.” Only reviews that violate Etsy’s actual review policies are eligible for removal — a review being old, or simply negative, isn’t grounds for takedown on its own, under either the old or new calculation.
- “My rating will jump the moment the update rolls out.” Etsy described the rollout as happening over the weeks following the March announcement, and the visible change for any individual shop depends entirely on that shop’s own review-age distribution — shops with a flat, consistent history across years will see little to no visible movement at all.
A 5-Minute Self-Check
You don’t need a spreadsheet to get a rough read on where you stand. Open your shop’s reviews page and sort by most recent, then scroll until you can eyeball roughly where each of the last few years’ worth of reviews sits:
Frequently Asked Questions
When did Etsy’s new review rating calculation take effect?
Etsy published the announcement in its seller handbook on March 13, 2026, with an update on March 25, 2026 after seller questions, and described the rollout as happening over the following weeks. Individual shops may have seen their displayed rating update on different dates within that window.
Does the new formula affect Star Seller status?
No. Star Seller evaluates message response time, shipping performance, and review average using its own recent, rolling window, which is separate from the shop-level star rating shown to buyers. This update changes only the public rating calculation, not Star Seller eligibility.
Can I request that Etsy remove an old negative review now that it counts toward my lifetime rating?
Only if the review violates Etsy’s actual review policies, such as containing prohibited content or being unrelated to the transaction. A review being old or simply unflattering is not grounds for removal under either the old or the new calculation method.
Will my rating go up or down under the new system?
It depends on your shop’s specific history. Shops with strong multi-year track records and a recent temporary problem tend to see their rating rise, since older good reviews now cushion the recent dip. Shops with a real issue in roughly the past one to two years tend to see their rating fall somewhat, since that period still carries significant weight instead of aging out at the old 12-month cutoff. Shops with a consistent rating across their whole history should see little to no change.
Does responding to a review still lock in its star rating?
Yes, this part of Etsy’s review system is unchanged by the rating-calculation update. Buyers can generally revise a review’s star rating for up to 100 days after the estimated delivery date, but if a seller responds to the review at any point during that window, the review locks and the buyer can no longer edit it.
Key Takeaways
- Etsy switched from a 12-month-only rating calculation to a lifetime calculation where review influence roughly halves each year, effective from its March 2026 announcement.
- In a modeled example, a shop with a recent rough patch but a strong multi-year history could see its displayed rating rise from 3.80 to roughly 4.43 — purely from the formula change.
- In a mirrored example, a shop that fixed a quality problem 1–2 years ago could see its rating fall from 4.95 to roughly 4.63, since that period still carries meaningful weight under the new formula.
- Star Seller eligibility is unaffected — it continues to run on its own separate, recent-performance window.
- Only reviews that violate Etsy’s actual policies are removable; age and low ratings alone are not grounds for removal under either system.
The Bottom Line
This is a mechanical change to arithmetic, not a new set of rules sellers need to strategize around. There’s nothing to game and nothing to request — the formula runs on the reviews you already have, weighted by age, and the honest response is to keep collecting good ones and let a real recent problem get genuinely resolved rather than waiting for it to age off a calendar. What’s worth doing is understanding which direction your own shop is likely moving, since a rating shift over the coming months is expected and explainable, not a sign something’s wrong with your account.
