5 Most Affordable CBD Oils Under $50 (2026 Buyer's Guide)
How we ranked these
We capped entries at $50 for a non-introductory bottle (no first-order promos that don't reorder at that price).
Every brand on this list can produce a current COA, and uses U.S.-grown hemp.
We deliberately excluded several discount-tier brands that didn't pass the COA freshness check — being cheap and being safe are not the same thing.
Competitor pricing was last re-verified on September 14, 2026 against each brand's own product pages, using the everyday one-time-purchase price rather than the subscription or promotional rate. Where a standing subscription discount materially changes the math, we give both numbers. Per-mg figures are bottle price divided by total labeled CBD. Prices drift; the date on this line is the date to trust it to.
Refreshed October 11, 2026: we re-read the pages that outrank this one for 'cheap cbd oil' and 'affordable cbd oil' (Innerbody's best-CBD-oil review, Upright CBD's affordable-CBD-oil guide updated September 23, 2026, and Vaping360's CBD price guide) and added the questions they answer that this page did not, as FAQs. Competitor entry prices were not re-checked on this pass; the September 14, 2026 date on the line above still governs them. Our own prices in the new FAQs are read from our product pages on the day of the refresh.

The ranking
$35 for a 500mg bottle of broad-spectrum, THC-free, fully tested CBD oil. Available in natural, fresh mint, and peruvian lime. Same bottle, same formula, same COA discipline as botanCBD's 6,000mg flagship — just sized for first-time users or for travel. COA available on request. Two honest notes. At $0.07 per mg this is not the cheapest milligram on the page — Lazarus's 1,500mg is $40, about $0.027 per mg, and Cornbread beats this $0.07 too — so what you are buying here is THC-free at the smallest credible commitment, not the lowest unit price. And if you don't need THC-free, our own full-spectrum 500mg bottle is $30 rather than $35, the same three flavors, $0.06 per mg; it contains trace THC.

We had this bottle at $27.99 and described it as broad spectrum. Both were wrong, and the correction matters: the 500mg Relief & Relaxation Tincture is $35 at the everyday one-time price — the same $35 botanCBD charges — and it is full spectrum, so it carries trace THC. CBDistillery's broad-spectrum (0% THC) line now starts at 1,000mg for $60, which is over this list's $50 cap, so there is no THC-free CBDistillery bottle that qualifies here at all. What is still true: the 30% subscription takes the 500mg to $24.50, which is the cheapest way into a credible full-spectrum oil we found, and they publish COAs. Trade-offs are unchanged — taste runs flat, no flavor variants in this tier, and customer-service reviews skew lower than the top of this list.

Lazarus has retired the old 750mg bottle; their smallest tincture is now a 30mL/1,500mg bottle at $40. If you qualify for their assistance program (veterans, long-term disability, low-income — 60% off), the same bottle drops to about $16, and it has more than twice the CBD of the bottle it replaced. The base product is U.S.-grown, full-spectrum, organic, in-house manufactured.

Medterra has renamed this line; what we listed as the Isolate CBD Tincture is now sold as Daily Relief CBD Isolate Oil. It is $39.99 for 500mg, or $0.080 per mg — the most expensive milligram on this page — and it carries the U.S. Hemp Authority seal. Isolate means there is literally no other cannabinoid in the bottle, which some users specifically want (extreme drug-test sensitivity, or known reactions to other cannabinoids). The standing 25% subscription brings it to $29.99, or $0.060 per mg, which is where this bottle actually makes sense. For most users, broad spectrum gives you more for the money.

Cornbread replaces Bluebird Botanicals on this list, because Bluebird no longer sells a CBD oil under $50 — their cheapest is now $54.95 and the Classic oil we used to rank here is $59.95. Cornbread's 750mg Whole Flower bottle is $49.99, just inside the cap, at $0.067 per mg. It is USDA Organic on the finished product, full spectrum with up to 2mg THC per serving, and sourced from Kentucky hemp flower only — no stalk or biomass filler, which is genuinely unusual at this price. Subscribe and save takes 20% off. Trade-offs: the taste is floral and earthy in a way people either like or really don't, there are no flavored options, and it contains trace THC. A direct geographic neighbor to botanCBD — both family-owned, both working Kentucky hemp.

The bottom line
Affordable CBD oil is real — but cheap CBD oil is also real, and the gap between them is where users get burned. Every brand on this list can produce a current COA and uses U.S.-grown hemp. Below this list, in the actual cheap tier, things get sketchy fast. The September 2026 re-check moved this page around more than we expected: Bluebird Botanicals priced itself off the list entirely, CBDistillery turned out to cost $35 rather than the $27.99 we had published, and Cornbread Hemp came in at #5. If the cheapest credible milligram is what you want, the Lazarus 1,500mg bottle is $40, about $0.027 per mg. If you qualify for their assistance program, that bottle is about $16. botanCBD's $35 500mg bottle is the starting point we recommend to first-time users who want THC-free, because it is the same product, formula, and COA discipline the daily-driver customers buy at 6,000mg, just sized down for the trial.
Where our drops fit on a budget
If you want the smallest credible commitment in a THC-free oil with a batch report you can request, start with the 500mg THC-free broad-spectrum drops at $35. If trace THC is fine and the lowest entry price on our shelf is the point, the full-spectrum 500mg is $30, or $0.06 per mg. Once you know your serving, the 1,500mg of either oil is the better per-mg buy, and the THC-free 6,000mg is the cheapest milligram we sell at about $0.0275. If the cheapest credible milligram anywhere is the whole question, the answer is still Lazarus Naturals at #3, and we would rather tell you that than pretend otherwise.
FAQ
What is the cheapest CBD oil that is still third-party tested?
On price per milligram alone, Lazarus Naturals is lowest on this list at about $0.027/mg, and it publishes per-batch lab reports. On entry price for a THC-free bottle with a COA available on request, botanCBD's $35 500mg broad-spectrum drops are the pick. Either way, the test is the same: a current lab report for that bottle. A $12 tincture with no report is cheap, not affordable.
Why is botanCBD's 500mg bottle ranked #1 when Lazarus is about $0.027 per mg?
Because they answer different questions. Lazarus is $40 for 1,500mg — $0.027 per mg, against $0.07 on this 500mg bottle — and if per-mg cost is all you are optimizing, that is the bottle to buy and we would rather say so than pretend otherwise. What botanCBD's 500mg bottle gives you instead is broad spectrum (genuinely THC-free, with the THC removed, where the Lazarus tincture is full spectrum), three flavors people actually finish, COA available on request, and the smallest credible commitment on this list if you are not yet sure CBD is for you. One correction worth flagging: we used to say CBDistillery undercut us here. It doesn't — that bottle is $35, the same price as ours, and it is full spectrum.
Are there cheaper CBD oils than these five?
Yes, and you should be careful. Below this list, brands often skip per-batch COA testing, source from unknown overseas hemp, or use isolate without saying so. The 'gas station CBD' tier has been investigated repeatedly by state regulators for content not matching label.
Why was Bluebird Botanicals removed from this list?
Price, not quality. Bluebird has been making well-tested CBD since 2012 and we ranked them here for a long time. But they reformulated and repriced the Classic line, and as of September 14, 2026 their cheapest CBD oil is $54.95 with the Classic tincture at $59.95 — above this page's $50 cap. The rule is the rule, so they come off. If the cap is not a hard constraint for you, they remain a credible brand.
Can I get even better pricing with subscribe-and-save?
On botanCBD, yes — subscribe-and-save drops the 500mg bottle further. Every other brand on this list discounts a subscription too, and on some of them it changes the ranking: CBDistillery goes to $24.50 (30% off), Medterra to $29.99 (25%), Cornbread takes 20% off, and Lazarus 15%. Read the recurring-charge terms before subscribing on any of them, and check whether the discount applies to every order or only the first.
How much does CBD oil cost?
Measured the way the price guides measure it, by price per milligram of CBD, a credible CBD oil in 2026 runs from about $0.02 per mg at the high-strength end to roughly $0.12 per mg for a small, low-strength bottle. Upright CBD's affordable-oil guide (updated September 23, 2026, read October 11) calls $0.05 to $0.07 per mg affordable and $0.02 to $0.05 highly affordable; Vaping360's price guide puts CBD products as a whole at $0.02 to $0.20 per mg, with the better tinctures averaging around $0.12. The five bottles on this list run $0.027 (Lazarus, 1,500mg for $40) to $0.080 (Medterra, 500mg for $39.99). Our own drops, priced from the product pages on October 11, 2026: the THC-free broad-spectrum drops are $35 for 500mg ($0.070/mg), $70 for 1,500mg ($0.047), $110 for 3,000mg ($0.037) and $165 for 6,000mg ($0.0275); the full-spectrum drops are $30 for 500mg ($0.060) and $65 for 1,500mg ($0.043). So the honest answer to 'how much does CBD oil cost' is: about $30 to $50 for an entry bottle, and $0.03 to $0.08 per milligram once you compare like for like.
How do I work out the price per mg of a CBD oil?
Divide the bottle price by the total milligrams of CBD on the label, and ignore the bottle size in millilitres — it tells you how much liquid you get, not how much CBD. Vaping360's worked example is $29.99 ÷ 250mg = $0.12 per mg; ours is $35 ÷ 500mg = $0.07 per mg. Two traps the guides flag. First, some labels give milligrams of 'hemp extract' or 'hemp oil' rather than milligrams of CBD, and some sell hemp seed oil, which contains no meaningful CBD at all; only a CBD figure counts. Second, the label number is a claim until the certificate of analysis for that batch confirms it, so check the COA's total CBD against the label before you trust the per-mg math. Our glossary has a short explainer on reading mg per mL if the label gives concentration instead of a bottle total.
What makes a cheap CBD oil too cheap to trust?
Not the price itself — Lazarus at $0.027 per mg is cheap and credible — but what is missing at that price. The guides we read agree on the same checklist. No batch-specific lab report, or a report you cannot match to the batch number on your bottle. A label that lists 'hemp extract' or hemp seed oil milligrams instead of CBD milligrams. Isolate sold under full-spectrum language. Hemp of unknown origin, where the brand cannot say what farm or country it came from. Innerbody ranks quality and safety above cost for exactly this reason: a bottle that fails the first two checks is not a bargain at any price. And Vaping360's standing advice is to skip gas stations, corner stores and websites that do not look credible, because that is where the untested tier lives. If a $12 bottle passes every check on this list, buy it; in our experience it does not. Our longer guide to the difference is Affordable CBD Without Cheap Quality.
Where is the lowest price per mg — a cheap small bottle or a stronger one?
The stronger one, almost always. Every price guide we read says the same thing: the more CBD in the bottle, the less you pay per milligram, because the carrier oil, bottle, dropper, lab testing and shipping cost roughly the same whether the bottle holds 500mg or 6,000mg. Innerbody averages its picks into cost per milligram precisely so a high-price, high-potency bottle can be compared fairly with a low-price, weak one. Our own ladder shows the effect: the THC-free drops go from $0.070 per mg at 500mg to $0.0275 per mg at 6,000mg, about two and a half times cheaper per milligram for the same oil. The catch is that a strong bottle only saves you money if you finish it, so start small until you know your serving — our serving-size guide walks through that — and then move up. If strength is the whole question, the strongest CBD oils list is the companion to this page.
Is a cheaper CBD isolate oil a better deal than full or broad spectrum?
Sometimes at wholesale, not reliably at retail. Isolate is the cheapest form of CBD to make, and Vaping360 notes that bulk isolate is the most cost-effective way to buy CBD by the gram — but the only isolate on this list, Medterra's 500mg oil at $39.99, is the most expensive milligram on the page at $0.080. What you give up with isolate is every other compound from the plant: it is CBD and carrier oil, nothing else, which is what buyers who want CBD only specifically want. Broad spectrum keeps the other cannabinoids and terpenes with the THC removed; full spectrum keeps the trace THC too. Innerbody's reviewers say they generally prefer full spectrum for that reason. Our take: pick the spectrum first, then compare price per mg within it. The comparison pages on isolate versus broad spectrum and isolate versus full spectrum lay out the trade-offs, and if THC-free is the requirement, our broad-spectrum drops are the budget entry on this list that is not isolate.
