The rent-versus-buy question is usually decided on intuition: short-term use should rent, long-term use should buy. The intuition is directionally right and quantitatively imprecise. The breakeven between rental and purchase depends on the specific rental rate, the specific purchase price, the resale value of the unit after use, and whether the patient’s need is for a 5 LPM, 10 LPM, or portable concentrator. The breakeven moves by several months depending on those inputs.
This article provides an explicit framework: rental rates by machine class in 2026 Indian pricing, breakeven tables at 6 / 12 / 24 / 36 month horizons, purchase-with-resale math that almost no one runs, the scenarios where rental clearly wins, the scenarios where purchase clearly wins, and the rent-to-own structures that occupy the middle ground. The goal is to let a family with a specific prescription and a specific budget make this decision on numbers, not on vibes.
Rental rates by machine class (2026)
Indian rental rates for home oxygen concentrators in 2026, based on market scan across metros and Tier-1 cities:
| Machine class | Rental range per month | Security deposit |
|---|---|---|
| 5 LPM home concentrator | ₹3,000 – ₹6,000 | ₹10,000 – ₹25,000 |
| 10 LPM home concentrator | ₹6,000 – ₹10,000 | ₹20,000 – ₹50,000 |
| Portable oxygen concentrator (POC) | ₹10,000 – ₹18,000 | ₹50,000 – ₹1,50,000 |
Three modifiers move these numbers:
- City tier. Metro rental is generally higher; Tier-2 and Tier-3 can be 15–25% lower for 5 LPM and 10 LPM units because local dealer operating costs are lower. Portable concentrator rental is more uniform across cities because the dealers renting them tend to be metro-based regardless of where the patient lives.
- Brand. Premium brand units (ResMed, Philips, Inogen, SimplyGo) rent at the top of the range; mid-tier brands (Oxymed, BPL, Nidek) sit in the middle; lower-tier and refurbished units sit at the bottom. For 5 LPM home concentrators the difference is smaller than buyers expect — rental is more of a commodity than new-unit sales.
- Rental duration. Month-to-month rentals sit at the top of the range; 6-month commitments typically get 5–15% discount; 12-month commitments 15–25%. Some dealers offer weekly rates that annualise higher than monthly rates but are flexible for short episodes.
Rental typically bundles: the unit, a nasal cannula, a humidifier bottle, a carry trolley, and one service visit per rental month. It does not usually include: electricity cost (patient’s burden), filter replacement (patient’s burden or add-on), and stabiliser (patient provides). POC rental sometimes includes extra batteries as an add-on.
Purchase prices (2026 reference)
To compute breakeven, match rental rates against purchase prices for the same equipment class:
| Machine class | New purchase price (2026) | Expected useful life |
|---|---|---|
| 5 LPM home concentrator (mid-tier) | ₹45,000 – ₹75,000 | 4–6 years typical, 8+ years possible |
| 5 LPM home concentrator (premium) | ₹65,000 – ₹95,000 | 5–7 years typical |
| 10 LPM home concentrator (mid-tier) | ₹95,000 – ₹1,55,000 | 4–6 years typical |
| 10 LPM home concentrator (premium) | ₹1,35,000 – ₹1,85,000 | 5–7 years typical |
| Portable oxygen concentrator (POC) | ₹1,85,000 – ₹3,50,000 | 3–5 years typical (battery life is the constraint) |
Lifespan here is unit hardware life under reasonable use in Indian conditions. Sieve bed replacement — typically needed every 3–5 years — extends the useful life meaningfully; ignoring sieve replacement shortens it.
The simple breakeven table
The simplest rent-versus-buy math assumes zero resale value at end of use. Purchase breaks even against rental when cumulative rental exceeds purchase price. For a 5 LPM mid-tier concentrator at ₹55,000 purchase price against ₹4,500/month rental:
- 6 months: rental cost ₹27,000 vs purchase ₹55,000 → rental wins by ₹28,000
- 12 months: rental cost ₹54,000 vs purchase ₹55,000 → approximately breakeven
- 18 months: rental cost ₹81,000 vs purchase ₹55,000 → purchase wins by ₹26,000
- 24 months: rental cost ₹1,08,000 vs purchase ₹55,000 → purchase wins by ₹53,000
- 36 months: rental cost ₹1,62,000 vs purchase ₹55,000 → purchase wins by ₹1,07,000
Rough breakeven for a 5 LPM is around 12 months of continuous use. This matches the intuition that 12+ months of use pushes toward purchase.
For a 10 LPM mid-tier concentrator at ₹1,25,000 purchase against ₹8,000/month rental:
- 6 months: rental ₹48,000 vs purchase ₹1,25,000 → rental wins by ₹77,000
- 12 months: rental ₹96,000 vs purchase ₹1,25,000 → rental wins by ₹29,000
- 18 months: rental ₹1,44,000 vs purchase ₹1,25,000 → purchase wins by ₹19,000
- 24 months: rental ₹1,92,000 vs purchase ₹1,25,000 → purchase wins by ₹67,000
- 36 months: rental ₹2,88,000 vs purchase ₹1,25,000 → purchase wins by ₹1,63,000
Breakeven for a 10 LPM is around 15–16 months of continuous use.
For a portable oxygen concentrator (POC) at ₹2,75,000 purchase against ₹14,000/month rental:
- 6 months: rental ₹84,000 vs purchase ₹2,75,000 → rental wins by ₹1,91,000
- 12 months: rental ₹1,68,000 vs purchase ₹2,75,000 → rental wins by ₹1,07,000
- 18 months: rental ₹2,52,000 vs purchase ₹2,75,000 → rental wins by ₹23,000
- 24 months: rental ₹3,36,000 vs purchase ₹2,75,000 → purchase wins by ₹61,000
- 36 months: rental ₹5,04,000 vs purchase ₹2,75,000 → purchase wins by ₹2,29,000
POC breakeven is around 20 months.
The pattern: the more expensive the unit, the longer the breakeven in months. Rental rates are economically tied to unit cost, but the markup ratio is slightly higher on less-expensive units, making breakeven shorter for them.
The purchase-with-resale math
The simple breakeven ignores residual value. A concentrator purchased for ₹55,000 and used for 18 months is not worth zero afterward — it can be resold through a refurbishment dealer, a trade-in program, or directly. Resale values in 2026 Indian market:
- 12 months use: 50–60% of purchase price
- 24 months use: 30–45% of purchase price
- 36 months use: 20–30% of purchase price
- 48 months use: 10–20% of purchase price
Resale assumes the unit is in good working order, ideally with a purity test confirming spec. Units with history of voltage damage, unauthorised repair, or known failures resell at a discount; some don’t resell at all.
Recomputing the 5 LPM ₹55,000 breakeven with resale:
- 12 months: rental ₹54,000 vs (purchase ₹55,000 − resale ₹30,000 = net ₹25,000) → purchase wins by ₹29,000
- 18 months: rental ₹81,000 vs (purchase ₹55,000 − resale ₹22,000 = net ₹33,000) → purchase wins by ₹48,000
- 24 months: rental ₹1,08,000 vs (purchase ₹55,000 − resale ₹18,000 = net ₹37,000) → purchase wins by ₹71,000
With realistic resale factored in, purchase pulls ahead at 12 months, sometimes earlier. At 6 months of continuous use, rental still wins but by a smaller margin than the simple table suggests:
- 6 months: rental ₹27,000 vs (purchase ₹55,000 − resale ₹38,000 = net ₹17,000) → purchase wins by ₹10,000
Even at 6 months, purchase-with-resale wins on paper if the resale happens smoothly. The rub: resale is a task, not a guarantee. Finding a buyer, negotiating price, handling the logistics, and dealing with the service-transfer takes time and effort. For a family dealing with a patient’s care, that effort is non-trivial.
The practical rule of thumb: at 6 months, rent unless the family has clear capacity to handle resale. At 12+ months, buy — the resale upside compounds the breakeven advantage.
When rental clearly wins
Rental is the right call in these scenarios:
Expected use <6 months on LTOT
Post-hospitalisation recovery, bridging therapy during a treatment cycle, oxygen support during a COPD exacerbation that’s expected to resolve, post-partum for a mother with transient hypoxia — all of these run 1–6 months typically. Rental sits under the breakeven for all unit classes; dealer handles service; no resale burden on the family.
Undefined duration
A patient whose prognosis is uncertain — newly-diagnosed ILD where disease trajectory is unclear, a patient being assessed for lung transplant, a patient with a potentially-reversible cardiac condition — benefits from rental until the prognosis stabilises. Converting to purchase later is always available; converting from purchase back to rental is not.
Trial-then-buy
A patient starting LTOT for the first time has usage-pattern uncertainty. How many hours per day will they actually tolerate oxygen? Does the unit fit their lifestyle? Do they tolerate continuous-flow delivery, or do they need pulse-dose? A 2–3 month rental trial resolves these questions before a commitment.
Travel or temporary relocation
A patient staying at a family member’s home for a few months, or travelling for extended treatment, can rent at the destination rather than shipping a purchased unit across cities.
Cash-flow constrained situations
Monthly rental smooths the cash outlay. For households where the ₹55,000–₹2,75,000 purchase price would be painful as a single payment, monthly rental is a cash-flow-manageable alternative. Interest-free payment plans from dealers (where available) can achieve similar smoothing for purchase; not all dealers offer this.
When purchase clearly wins
Purchase is the right call in:
Chronic LTOT >18 months expected
Severe COPD, idiopathic pulmonary fibrosis, pulmonary hypertension with documented resting hypoxaemia — conditions where oxygen therapy is indefinite or for years. 18 months is comfortably past the breakeven for all unit classes. Purchase breaks even and then compounds savings.
Hill-station and remote locations
Where the local rental market is thin — in hill stations (Leh, Manali, Shimla, Mussoorie, Darjeeling, Ooty, Gangtok) or in Tier-3 and rural locations — rental dealers either don’t exist or charge a premium that moves breakeven earlier. A remote patient is typically looking at 1.5–2x metro rental rates, which shifts breakeven from 12–16 months down to 8–10 months.
Service-network limited locations
Where authorised service is rare, a rental-returned unit may take 3–4 weeks to get swapped out. Owning the unit (with a local authorised service channel or at minimum a manufacturer importer that handles shipped service) is more predictable than rental, even if the rental dealer is ostensibly on the hook.
Multiple patients in household
Two patients in the same household or extended family who need concentrators sequentially or concurrently — an elderly parent with COPD, then later a second parent — justify ownership. Rental for two users sequentially becomes expensive fast.
Rent-to-own structures
A hybrid: the patient rents for 6–12 months with a pre-agreed conversion price at which ongoing rental converts to ownership. Structure variants:
- Credit-all-paid-rent. After 12 months of rental, the cumulative rental paid counts entirely toward purchase price. If purchase price is ₹55,000 and cumulative rent paid is ₹54,000, the conversion payment is ₹1,000 plus any GST adjustment. This is the most buyer-favourable structure but uncommon at market prices.
- Credit-partial-rent. 40–60% of cumulative rental credits toward purchase. Conversion payment at month 12 is purchase price minus credit. This is the most common structure.
- Flat conversion premium. Rental for any duration, with conversion to ownership at any point for a flat discounted price (e.g., ₹40,000 for the ₹55,000 unit). No rental-counting but an attractive upfront conversion discount.
- Month-to-month with right-to-buy. Rental continues indefinitely, and the patient can convert at any point for a discounted price that ages with the unit.
Rent-to-own helps in the “duration uncertain, likely long” case. It also helps when the family wants to start with rental (low commitment, short-term-looking) but sees rising usage and wants to convert without a fresh purchase decision. The terms matter — an unfavourable rent-to-own structure can be worse than either rental or purchase alone.
The post-COVID market context
The 2021 COVID overstock affected the rental market significantly in 2022–2024. Dealer inventories were elevated, rental rates softened by 10–20%, and conversion-to-buy prices dropped. By 2025–2026, the overstock has cleared and rental rates have firmed to the 2026 ranges quoted above. New units are in normal supply, and resale value for good-condition used units is somewhat lower than pre-COVID because the market absorbed a lot of used inventory already.
GST and tax treatment
Both rental and purchase of oxygen concentrators attract GST at 12% in India (as of 2026). Rental GST is charged on each monthly invoice; purchase GST is a one-time payment on the sale invoice. For patients whose medical expenses qualify under Section 80DDB of the Income Tax Act (specified diseases), both rental and purchase costs are deductible subject to the section’s limits.
A decision matrix
To tie the framework together:
| Expected use | 5 LPM concentrator | 10 LPM concentrator | POC |
|---|---|---|---|
| <6 months | Rent | Rent | Rent |
| 6–12 months | Rent, consider rent-to-own | Rent | Rent |
| 12–18 months | Buy (with resale plan) | Rent-to-own | Rent |
| 18–24 months | Buy | Buy | Rent-to-own |
| 24+ months | Buy | Buy | Buy |
| Uncertain, possibly long | Rent-to-own | Rent-to-own | Rent-to-own |
| Hill-station / remote | Buy | Buy | Buy |
The 10 LPM and POC columns lean toward rental longer because the absolute purchase price is higher and the breakeven is deeper. The 5 LPM column flips to purchase earliest because the unit is inexpensive and resale market for 5 LPM units is liquid.
Practical takeaway
Rent if the expected use is under six months, if the duration is undefined, or if the patient is in a trial-before-commit phase. Buy if the expected use is over 18 months, if the patient is in a hill-station or remote service location, or if multiple patients in the household will use the unit sequentially. The middle range (6–18 months) is where the math matters: run the breakeven table with the specific rental rate, specific purchase price, and realistic resale value for the unit class. A 5 LPM concentrator breaks even around 12 months; a 10 LPM around 15–16 months; a POC around 20 months. Factor resale into purchase cost — it typically pulls breakeven earlier by 3–6 months. Consider rent-to-own when duration is uncertain but leaning long, and read the conversion structure carefully. Don’t decide this on vibes; the numbers move the answer by several months one way or the other, and the wrong call costs ₹25,000–₹1,50,000 over the use period. Consult your pulmonologist on the expected duration of therapy before committing to either path.
