The drink package break-even is higher than the bar menu suggests.

Cruise lines sell drink packages as a one-line decision: unlimited drinks, one flat fee. The spreadsheet is messier. You have to add the service charge (the automatic tip, usually 18% to 20%), respect the per-drink dollar cap, and multiply by every adult in the cabin because of the "everyone buys or nobody buys" rule.

Here is the 2026 math for the three lines most Vacation Math readers actually sail.

The formula (spell it out once)

Break-even drinks per day equals all-in package cost per person per day divided by your typical drink price. All-in means the advertised daily rate plus the automatic beverage gratuity. Your typical drink price is not the $14 menu ceiling. It is the mix you actually order (beer, wine by the glass, cocktails, specialty coffee).

Two more adjustments that move the answer:

• Cabin rule: Carnival, Royal Caribbean, and Norwegian require every adult of legal drinking age in the stateroom to buy if one does. A light drinker in the cabin raises the couple's break-even.
• Sea-day vs port-day: Embarkation afternoons and long port days rarely hit the same pace as a sea day. A 7-night sailing is not seven identical drinking days.

Carnival CHEERS! (2026)

Carnival's CHEERS! Beverage Program is the cleanest sticker to work with because Carnival publishes an all-days rate. Per Carnival's site and help pages, pre-purchase runs $69.95 per person, per day plus a 20% service charge (about $83.94 all-in). Onboard purchase is higher: $74.95 plus 20% (about $89.94). The Points Guy's February 2026 line-by-line guide lists similar all-in figures of about $82.54 advance and $88.44 onboard.

What you get: beer, wine by the glass, mixed drinks, specialty cocktails, soda, juices, mocktails, energy drinks, specialty coffees, teas, and most bottled water, plus a discount on wine bottles. Alcoholic drinks are capped at 15 per person in a 24-hour period. Drinks over $20 are not free; Carnival applies a 25% discount on those pours (and on wine bottles) under the current CHEERS! terms. If one adult in the cabin buys CHEERS!, every other adult in that cabin must buy it too.

Carnival's published sample menu (subject to change) puts beer from about $6.50, wine by the glass from about $9.50, and mixed drinks roughly $7.50 to $20. If your real mix is closer to beer and house wine than $14 cocktails, the break-even climbs toward 8+ drinks.

Royal Caribbean Deluxe Beverage Package (2026)

Royal Caribbean's Deluxe Beverage Package is priced by ship and sailing. TPG (Feb 2026) lists a range of about $56 to $105 per person, per day before the 18% gratuity. Independent 2026 tracking puts the fleet median near the mid-$70s to mid-$80s before tip. Use your Cruise Planner number, not a blog median.

The package covers beer, wine by the glass, spirits, cocktails, soda, juices, mocktails, energy drinks, specialty coffees, teas, and premium bottled water, with wine-bottle discounts. The hard ceiling is $14 per single beverage. Anything above that is billed as the difference (plus gratuity on the difference). Starbucks on ships, specialty beers, room service, and minibar items are out. As of March 15, 2026, Coca-Cola Freestyle machines and the souvenir cup are no longer included with Deluxe (you can still buy a Freestyle cup onboard). Same cabin rule as Carnival: one adult buys, every legal-age adult in the cabin buys.

That is why the popular "5 to 7 drinks" rule of thumb undershoots. It often starts from the pre-gratuity sticker and assumes every order hits the $14 cap. Real menus mix $8 beers with $13 cocktails, and embarkation day is half a day.

Norwegian Free at Sea (2026)

Norwegian is the odd one out because of Free at Sea. When the promo is attached to your booking, the beverage package itself is included and you pay the mandatory gratuities of about $28.50 per person, per day for the open-bar and specialty-dining components (TPG, Feb 2026; mirrored in Norwegian's 2026 Free at Sea explainers). That drops the drink break-even to roughly 2 to 3 drinks per day at typical cocktail prices. Standard Free at Sea covers pours typically up to about $15; higher pours take an upcharge.

For sailings beginning February 1, 2026, Norwegian also sells Free at Sea Plus as a $49.99 per person, per day upgrade (often $15 off if crew prepaid service charges are already on the reservation). Plus adds unlimited Starbucks (one drink per visit), signature-collection wine and Champagne, bottled water, energy drinks, fresh juices, top-shelf spirits, streaming Wi-Fi, and open bar at Great Stirrup Cay. It does not replace the ~$28.50 beverage/dining gratuities. Norwegian's own FAQ notes that prepaid service charges do not cover bar, beverage, or specialty dining gratuities. Treat Plus as a premium-extras buy, not a cheaper drink package.

Policy note: beginning March 1, 2026, standard Free at Sea no longer covers alcoholic drinks at Great Stirrup Cay; Plus (or a la carte) is required for the island open bar. Still subject to the cabin-wide purchase rule.

Side-by-side (one adult, sea-day pace)

For a couple on a 7-night Carnival or Royal sailing where only one person drinks seriously, the package often costs $1,100 to $1,300 for the cabin before anyone orders a soda. That is the number to put next to a la carte, not the single-person daily rate on the marketing page.
