K-Cup Caffeine Calculator
A K-Cup holds a fixed amount of coffee, and a fixed amount of caffeine comes with it. Choosing a bigger cup size on your Keurig doesn't add caffeine — it just spreads the same dose through more water. Pick a brand and a brew size below to see both numbers at once: what's actually in the pod, and how concentrated it ends up in your mug.
How much caffeine is in a K-Cup? Keurig's own stated range is 75–150 mg per pod. Most mainstream brands — Green Mountain, Dunkin', McDonald's — land around 95–130 mg. Starbucks runs slightly higher at 120–135 mg, and its 2X line reaches roughly 260 mg. Death Wish, by its own official product pages, is 140–180 mg depending on roast — far less than the 300–700+ mg some sites still claim.
Death Wish's real number is smaller than its reputation
An old 2015 lab test (later disputed by other labs) is the source of the wild "700+ mg" claims still repeated across the internet today. Death Wish's own current product pages state it plainly: Light Roast pods are about 140 mg, Medium Roast about 165 mg, and Dark Roast about 180 mg, each based on a standard 6 oz serving. Still genuinely strong — well above a typical K-Cup — but nowhere near the figure most blog posts quote.

from the whole pod — this doesn't change with brew size
Figures come from brand-published product information where available (Death Wish) and from Keurig's own stated 75–150 mg range plus widely compiled brand estimates elsewhere. Actual caffeine varies by bean origin, grind and how full your reservoir runs — treat these as good estimates, not lab measurements.
Same pod, different setting: what really changes
Press 6 oz and the pod's caffeine lands in a small, strong cup. Press 12 oz and the same caffeine spreads through twice the water — weaker to taste, but not weaker in total dose. The bar below shows both at once for your selected pod.
The one exception: running a pod twice
The first brew extracts most of the caffeine available in the grounds. Run the same used pod through a second cycle and you're mostly getting hot, coffee-tinted water — the total caffeine across both cups barely exceeds what one cycle already pulled out. Doubling the water doesn't double the pod's yield either way.
Complete K-Cup caffeine chart
Mainstream brands (8 oz brew)
| Brand / pod | Caffeine, 8 oz brew |
|---|---|
| Keurig's own stated range (any brand) | 75–150 mg |
| Green Mountain Coffee Roasters | 95–120 mg |
| Dunkin' | 100–120 mg |
| McDonald's | 100–120 mg |
| Peet's Coffee | 120–140 mg |
| Starbucks (regular lines) | 120–135 mg |
| Starbucks Blonde Roast | ~135 mg |
| Extra Bold pods (any brand, ~30% more grounds) | ~150 mg |
| Starbucks 2X | ~260 mg |
Starbucks 2X is a genuinely different product, not just a stronger regular pod — it blends ground Arabica with added coffee extract to roughly double the caffeine of a standard Starbucks K-Cup.
Death Wish and other high-caffeine pods (brand-stated figures)
| Pod | Caffeine, standard serving |
|---|---|
| Death Wish Light Roast | ~140 mg (6 oz serving) |
| Death Wish Medium Roast | ~165 mg (6 oz serving) |
| Death Wish Dark Roast | ~180 mg (6 oz serving) |
| Shock Coffee | 100–250 mg (range varies by source) |
These are Death Wish's own current product-page figures, based on the standard 6 oz brew their packaging recommends. Brewing the same pod at 10 or 12 oz doesn't add caffeine — it just makes a bigger, weaker cup from the same dose, per the general Keurig mechanic described above.
Half-caff and decaf
| Pod type | Caffeine |
|---|---|
| Half-caff pods (any brand) | Roughly half of that brand's regular pod |
| Decaf K-Cups (any brand) | 2–15 mg |
Decaf is not zero. The decaffeination process removes most, not all, of the caffeine, which is why even a decaf K-Cup carries a small measurable amount.
What actually predicts a K-Cup's caffeine
- Roast level, counterintuitively. Light roasts generally carry slightly more caffeine than dark roasts of the same bean, because longer roasting burns off a small amount of it. A "bold" or "dark" label describes flavour, not strength.
- Bean type. Robusta beans carry roughly double the caffeine of Arabica. High-caffeine novelty brands like Death Wish blend in Robusta specifically to push the number up.
- Grounds per pod. "Extra Bold" pods pack about 30% more ground coffee into the same size K-Cup, which is the honest way to raise caffeine rather than relying on roast marketing.
- Brew size — for concentration, not total. As covered above, this changes how strong the cup tastes, not how much caffeine the pod contained to begin with.
The "light roast has more caffeine" surprise
It's one of the most counterintuitive facts in coffee, and it applies to K-Cups exactly as it does to any other bean. If you're choosing a pod specifically to reduce caffeine, picking a lighter roast doesn't help — if anything, it can mildly work against you. Bean type (Robusta vs Arabica) and grounds-per-pod matter far more than roast colour.
K-Cup vs regular drip coffee vs café coffee
| Drink | Caffeine |
|---|---|
| Starbucks 2X K-Cup, 8 oz | ~260 mg |
| Death Wish Dark Roast K-Cup, 6 oz | ~180 mg |
| Starbucks Grande Pike Place, brewed in-café | 310 mg |
| Drip coffee from a carafe machine, 8 oz | ~95–140 mg |
| Standard K-Cup, 8 oz | ~95–130 mg |
| Half-caff K-Cup, 8 oz | ~50–65 mg |
| Decaf K-Cup, 8 oz | 2–15 mg |
A standard K-Cup runs slightly weaker on average than coffee brewed from a carafe machine at home, mainly because a full-size drip machine typically uses more grounds per cup than a single K-Cup pod is designed to hold. The gap closes or reverses with Extra Bold pods, and disappears entirely once you're comparing against genuinely high-caffeine pods like Death Wish or Starbucks 2X.
How many K-Cups a day is safe?
The U.S. Food and Drug Administration cites 400 mg a day as an amount not generally associated with negative effects in healthy adults.
| Pod | Pods to reach 400 mg |
|---|---|
| Standard K-Cup (~110 mg) | About 3.5 |
| Starbucks regular (~128 mg) | About 3 |
| Death Wish Dark Roast (~180 mg) | About 2.2 |
| Starbucks 2X (~260 mg) | About 1.5 |
Three standard K-Cups a day is a common, unremarkable habit that lands comfortably under the guideline. The math changes fast with high-caffeine pods — two Death Wish cups or a single Starbucks 2X plus a regular cup can put you at or near 400 mg well before the day is over. Lower ceilings are commonly cited for some groups: around 200 mg a day in pregnancy, and roughly 100 mg for adolescents. Sensitivity varies a great deal between individuals. Talk to a doctor or pharmacist if you're pregnant, have a heart condition or anxiety disorder, or take medication that interacts with stimulants.
K-Cup caffeine: frequently asked questions
How much caffeine is in a K-Cup?
Keurig itself states a range of 75–150 mg per pod. Most mainstream brands fall between about 95 and 130 mg for a standard 8 oz brew.
Does a bigger Keurig brew size mean more caffeine?
No. The pod contains a fixed amount of coffee and caffeine. Choosing a larger brew size setting passes more water through the same grounds, which dilutes the cup rather than adding caffeine to it.
How much caffeine is in Death Wish K-Cups?
By Death Wish's own current product pages: approximately 140 mg for Light Roast, 165 mg for Medium Roast, and 180 mg for Dark Roast, each based on a standard 6 oz serving. These figures are considerably lower than older, widely repeated claims of 300–700+ mg per cup.
Why do some websites say Death Wish has 700 mg of caffeine?
That figure traces back to a 2015 lab test that produced unusually high results, which other independent labs have not consistently replicated. Death Wish's own current published figures for its K-Cups are 140–180 mg, depending on roast.
Do light roast K-Cups have more caffeine than dark roast?
Generally yes, slightly. Longer roasting burns off a small amount of caffeine, so a light roast of the same bean typically carries a bit more than a dark roast version. It's a modest effect, not a dramatic one.
Which K-Cup has the most caffeine?
Among verifiable figures, Starbucks 2X leads at roughly 260 mg per 8 oz cup. Death Wish's dark roast, at about 180 mg per 6 oz serving, is the strongest of the widely available "extreme" novelty brands based on the company's own stated figures.
Do decaf K-Cups have any caffeine?
Yes, a small amount — typically 2 to 15 mg per cup. Decaffeination removes most but not all of the caffeine.
What's the difference between a regular and an Extra Bold K-Cup?
Extra Bold pods pack roughly 30% more ground coffee into the same size K-Cup, which raises caffeine to around 150 mg per 8 oz brew — a real difference in dose, not just a stronger-tasting roast.
Does running a used K-Cup through the machine twice give you more caffeine?
Very little more. The first brew extracts most of the available caffeine from the grounds, so a second pass through the same pod yields mostly hot water with residual coffee flavour rather than a meaningful second dose.
Sources and method
Death Wish figures come directly from the company's current product pages for its Light, Medium and Dark Roast single-serve pods, each stated per standard 6 oz brew. Keurig's 75–150 mg range is the company's own published figure covering K-Cups broadly. Other brand estimates (Green Mountain, Starbucks, Dunkin', McDonald's, Peet's) are not individually published as exact milligram figures by those companies and are compiled from independent testing and caffeine-reference sources; they are presented as ranges rather than single numbers for that reason.
