Smart ring cost: what every brand charges over one, three and five years

The four parts of a smart ring's cost

Ask what a smart ring costs and most answers stop at the sticker. That's one part of four. The full cost of owning one looks like this:

1. The ring price. Paid once. It moves with sales and clearance, so we link to the live price instead of printing a number.
2. Required fees. Paid every month or year for as long as you want the ring's full insights. This is the part that grows, and it's the part most product pages mention last.
3. Optional extras. Protection plans and paid add-on features. You choose these, which makes them a fair trade rather than a toll.
4. Costs nobody invoices. The phone a ring needs, a battery you can't replace, a charging case that may or may not be in the box, and whose return policy you're buying into.

This page adds all four up using each brand's own published policy, every one checked on September 19, 2026 and linked so you can check it again. It's the cost math behind our whole cost and subscriptions hub and behind the rankings in the best smart rings without a subscription.

Every brand's fee policy, quoted

One brand charges a required fee. The rest don't, though two sell optional extras and one swaps the fee for a phone requirement. Here is each policy in the brand's own words.

All policies checked September 19, 2026. Fees are US prices before sales tax.

We left one ring out on purpose. The Amazfit Helio Ring still has Amazon listings, but Amazfit's US store pages for it returned 404 when we checked and its subscription wording differs by region, so we couldn't confirm it's still sold in the US. For each brand's policy line by line, with the exact phrases to look for on a product page, see do smart rings require a subscription.

The 1, 3 and 5-year fee math for every ring

Here is what each ring's required plan adds over one, three and five years. Only the two Oura rings have a number above zero, and it's the same membership for both: buying the older Ring 4 doesn't change the fee. The last column links to the live price, because that's the only honest way to show a number that changes daily.

That's the whole “Oura ring subscription vs no subscription” question in one box. The ring price is fixed the day you buy. The fee keeps running for as long as you want more than three scores, and Oura offers no way to buy it out. The monthly plan costs a little more than the annual one over a year, so if you know you're staying, annual is the cheaper route. Every plan detail, including the one-month trial and who doesn't need to pay at all, is in our breakdown of what Oura's membership costs.

How to read “ring price + fees”

Every total on this site reads “ring price + fees” rather than a single dollar figure. That's deliberate. Ring prices change with sales, bundles and clearance; after Oura Ring 5 launched, for example, Gizmodo reported a clearance discount on Oura Ring 4 at Amazon. A price we typed in September could be wrong by October. The fee, by contrast, is the brand's own published policy, so we can quote it with a source and a date.

To get your real number:

1. Click the live price link for the ring you're considering (the “Check on Amazon” column).
2. Add the fee column for the number of years you expect to wear it.
3. Add any optional extras you actually want (the next two sections).
4. Add sales tax, which none of our figures include.

For a RingConn or a Galaxy Ring, step 2 is zero, so the price you see is the price you pay. For an Oura ring, step 2 is $209.97 over three years on the annual plan. Ultrahuman's Ring PRO and Circular Ring 2 aren't sold on Amazon.com, so their row says “Brand store only” and you'll need to check the price on the brand's own site. Our methodology explains how fee math feeds the cost-of-ownership score, which carries 30% of every ring's rating.

What's locked if you don't pay

A fee only matters if something stops working without it. Here's what each brand holds back when you don't pay.

• Oura: almost everything. Oura's support page says that without a membership you'll “only be able to see your three daily Oura scores (Readiness, Activity, and Sleep), ring battery, basic profile information, app settings, and the Explore content” ( Oura Support). Oura's store says the membership “unlocks personalized insights, an AI health companion, and new features as they arrive.” Anything not on the free list, which by our reading includes the detail behind those three scores, needs the plan. We go item by item in what the Oura Ring does without a subscription.
• RingConn: nothing. RingConn's Gen 2 page says “No Subscriptions” and “Multi-dimensional health monitoring included,” and The Gadgeteer's Gen 3 review found no locked tier at all.
• Samsung: nothing is locked behind a fee, but some features are locked behind a phone. Energy Score insights need a compatible Samsung Galaxy AI phone, and Double Pinch and Find My Ring don't work on other Android brands. The details are in does the Galaxy Ring need a subscription.
• Ultrahuman: your core data is free. Two named features, Cardio Adaptability and Cycle & Ovulation Pro, are paid PowerPlugs. See Ultrahuman's subscription costs.
• Circular: core features are included; some future features will cost Circular Coins, per Tech Advisor's review.
• WHOOP isn't a ring, but it's the other big membership name, and it goes further than Oura: the staff reply above says data collection and analysis stop when the membership ends. If that's the fee you're trying to escape, see WHOOP alternatives without a subscription.

Optional extras, and what they cost

Optional extras are the honest version of a subscription: the core product works, and you choose whether to pay for more. Here is every one we found, with its published price where the brand shows one.

• Oura protection plans. Oura's store offers optional protection at $45 for two years or $60 for three (Oura store). Weigh that against the standard terms: one year from purchase, with batteries excluded as consumable parts (Oura warranty FAQ). A protection plan sits on top of the membership, not instead of it.
• RingConn Product Protection. Optional two- and three-year plans for Gen 3, Gen 2 and Gen 2 Air, US only and bought at checkout. RingConn's FAQ says “The battery is included as part of the overall device” ( RingConn FAQ), which matters because the standard one-year warranty excludes normal battery capacity loss. We didn't find the plan price on the pages we checked.
• Ultrahuman PowerPlugs. Cardio Adaptability at $24/year and Cycle & Ovulation Pro at $39/year on Ultrahuman's US buy page. Two wrinkles: Ultrahuman's HSA/FSA page lists Cycle & Ovulation Pro at $39.99, and the5krunner reported in May 2026 that PowerPlugs were free for the first 12 months with later pricing undisclosed. Check the price at checkout.
• UltrahumanX. Optional coverage starting at $36/year that covers accidental damage and one Ring PRO replacement (UltrahumanX FAQ).
• Circular Coins. Tech Advisor reports that some future Circular features “need virtual coins,” which can be bought. We found no published Coin price.

We don't add any of these to the fee table, because none is required to see your data. If you want one, add its price yourself. Before you buy a protection plan, compare it with the standard warranty; our smart ring warranty and returns guide lays every brand's terms side by side.

Costs nobody sends you a bill for

Your phone

The Galaxy Ring charges no fee, but it doesn't work with iPhone at all, and its best features need a Samsung Galaxy phone. RingConn Gen 2 and Gen 2 Air need iOS 17 or Android 10 or newer. If your phone doesn't qualify, the real cost of that ring includes a new phone. For Ultrahuman's Ring PRO, the phone requirements weren't published on any Ultrahuman page we checked, so confirm with Ultrahuman before ordering.

A battery you can't replace

You can't swap a smart ring battery yourself, at least on the rings whose makers say so. Oura's safety page describes a “rechargeable, non-replaceable” lithium polymer battery of 15 to 22 mAh depending on size (Oura Support), and RingConn says its batteries are “not designed for user replacement.” Oura's warranty excludes batteries; RingConn's excludes normal capacity loss. The only battery-aging figure we found from any brand is Ultrahuman's for the Ring AIR (not sold in the US): about 500 charge cycles, with “a gradual reduction in battery life” expected after one to two years (Ultrahuman FAQ). So read our five-year column as “if the ring lasts that long.” No brand promises it will. Our guide to smart ring battery lifespan covers what each brand does when a battery fades.

A charging case, or the lack of one

RingConn Gen 2 and Gen 3, the Galaxy Ring and Ultrahuman's Ring PRO include a charging case. Oura's rings and RingConn's Gen 2 Air don't. If you travel and want one for an Oura ring, it's a third-party purchase; see smart ring chargers and charging cases.

Sizing and returns

Most brands give you a sizing kit free, and you should use it: no brand says its sizes match another's. Two small exceptions: Oura's Ring 5 kit on Amazon is sold rather than free, though Android Police reported it comes with a matching Amazon credit toward the ring, and Circular charges a small fee for its physical replica-ring kit. Where you buy also matters. Amazon-sold rings (Oura, RingConn, Galaxy Ring) follow Amazon's return process; Ultrahuman and Circular are brand-store only, with their own terms.

Pre-tax money can lower the bill

Every major brand labels its ring HSA/FSA eligible, and Oura says a prepaid membership can be paid with HSA or FSA funds when it's bought with a new ring (Oura Support). There is a catch: the IRS excludes expenses that are “merely beneficial to general health” (IRS), which is why checkout partners like Flex use a telehealth consult and may issue a Letter of Medical Necessity. Check with your plan administrator. Our smart ring HSA/FSA guide goes brand by brand.

How to price a ring before you buy

Seven checks, in the order that saves the most money:

1. Find the fee on the brand's support page, not the ad. Marketing pages bury it; support pages state it.
2. Read what works without paying. A fee that unlocks one niche feature is a different thing from a fee that unlocks your sleep data.
3. Multiply the fee by the years you'll wear the ring. Three years is a sensible planning window; the table above does five as well.
4. Check your phone against the ring's requirements. A no-fee ring that needs a new phone isn't a no-cost ring.
5. Check what's in the box. Charging case, charger, sizing kit.
6. Read the battery line in the warranty. It's the part most likely to fail and the part most often excluded.
7. Check where it's sold. Ultrahuman's Ring PRO is a US pre-order from its own store (“ships October 10th onwards” when we checked) and isn't on Amazon.com.

Run those checks on every ring and the field narrows fast. If you want every ring's specs in one grid, the smart ring comparison chart has them.

When paying Oura's fee can make sense

We build this site for people who'd rather not rent their own sleep data, but a fair cost page has to say when the fee buys something real. The strongest case for Oura is evidence. The best independent study we found for this site's question, Dial et al. in Physiological Reports (2025), compared Oura Gen 3 and Gen 4 against a Polar H10 chest strap across 536 nights in 13 adults, and the Oura rings agreed most closely of the wearables tested: resting heart rate error about 1.9% and HRV error about 6% for Gen 4 (Dial et al.). The study was funded by the US Air Force Research Laboratory and its authors declared no competing interests.

Paying can be a reasonable call if:

• You'll use the insights daily and published validation matters more to you than the fee.
• You can pay with pre-tax money. A prepaid membership bought with a new ring can go on an HSA or FSA card, per Oura, subject to your plan's rules.
• You don't actually owe it. Oura says Gen2 owners “do not require an Oura Membership,” and some early Gen3 buyers kept grandfathered lifetime plans. Anyone buying new pays the regular rate; Oura says there “currently is no option to purchase or upgrade to a Lifetime Membership.”

If none of those fit, the no-fee picks above cover the same basics without a running bill. You can also close the evidence gap yourself with a chest strap; how accurate smart rings are covers every study we found.
