About $900 a year — that’s the swing for a household that swaps two-cocktails-out a week for two-cocktails-in. A bar charges $14–18 for a drink. The same drink at home, accounting for the bottles you’ve amortized across many pours, costs about $3. The math holds even if you buy decent bottles.
What follows is the bottle-amortization model, which is the only honest way to look at the cost of a home cocktail. A single bottle of gin doesn’t make a single drink — it makes 17. Once you’re thinking in pours per bottle instead of dollars per bottle, the home math gets clear.
The bottle-amortization model
A standard bottle of spirits is 750mL — about 25 ounces. A standard cocktail uses 1.5 ounces of base spirit. So a bottle of gin is 17 cocktails, give or take.
A $30 bottle of decent gin, divided across 17 pours, is $1.76 per drink. A $20 sweet vermouth is 25 pours per bottle (a typical Negroni uses 0.75 oz), or about $0.80 per pour. A bottle of bitters is 100+ dashes, or roughly $0.10 per drink.
A Negroni at home: $1.76 + $0.80 + $0.80 (Campari, similar math) + $0.10 (bitters) ≈ $3.50. The same drink at most bars: $14–18.
Now multiply by frequency.

What’s worth stocking
The starter bar is small. About six bottles, maybe $200 total, that cover most of the classic cocktail canon for at least a year of casual home drinking.
- Gin ($25–30) — for Negronis, gin & tonics, martinis.
- Vodka ($20) — neutral; for a vodka soda or a Moscow mule.
- Bourbon ($25) — old fashioned, whiskey sour, manhattan.
- Tequila ($25) — margarita, paloma. Reposado is the most versatile.
- Sweet vermouth ($15) — Negroni, manhattan, perfect martini.
- Dry vermouth ($12) — martini, gibson.
- Campari ($28) — Negroni, americano, jungle bird.
- Angostura bitters ($10) — old fashioned, manhattan, lasts a year.
- Lemons & limes (handful per week, $3) — citrus is non-negotiable.
That’s about $170. Three more bottles you might want over time: a triple sec ($15) for margaritas and sidecars, an amaro like Montenegro ($30) for after-dinner drinks, and a bottle of mezcal ($35) if you want to play. Don’t buy them all at once.
What we explicitly do not buy in the starter kit: simple syrup (you make it: 1:1 sugar to hot water, shake, store in the fridge a month), grenadine (the bottled stuff is awful; if you need it, see a homemade pomegranate version), bottled sour mix (truly bad, and not necessary).
Three drinks that actually pay off at home
If you are starting from zero, prove the math to yourself with these three. They’re three-ingredient, no-shaker, and forgiving. Stir, don’t shake.
Negroni. Equal parts gin, sweet vermouth, Campari. Stir over ice 30 seconds. Big rocks glass, big ice cube, orange peel. Bar price: $14. Home cost: $3.50. The cocktail that makes the case for itself.
Old Fashioned. 2 oz bourbon, 1 sugar cube (or a teaspoon of simple syrup), 2 dashes Angostura. Stir over ice 30 seconds. Orange peel. Bar price: $15. Home cost: $3. Most bars pour a worse one than you can make.
Gin & Tonic. 2 oz gin, 4 oz tonic, lime wedge, ice. Bar price: $12. Home cost: $1.50. Boring on paper, excellent in practice if the gin is good.
Make all three a few times. Once you trust them, the rest of the canon opens up.

What the math doesn’t say
A few honest caveats. The bar charge isn’t only for the liquid — it’s also for the room, the music, and someone else doing the work. There’s a value to going out that doesn’t fit on a spreadsheet, and the savings argument doesn’t say “never go to bars.” It says “if you currently have a cocktail-out habit you’d rather have a cocktail-in habit, here’s what flipping it costs.”
The other caveat: drinking more at home because it’s cheaper isn’t a savings. If the goal is to drink less, this is also the right setup — making cocktails at home tends to slow you down, because you’re doing the work.
A note on the math
The $900 figure assumes two cocktails out per week, $14 each (a midrange American bar in 2026), and $3.50 per home cocktail across reasonable spirits. Heavier drinkers and pricier markets see higher gross savings. Lighter drinkers and cheaper bars see less. The bottle-amortization math doesn’t change.
