Here are some sample menus and pictures of drinks I've found around the internet.  
The Starbucks frappucino's aren't included if you get them from the Starbucks Kiosk on the bigger ships.  They are included if you get them from elsewhere on ship like Cafe-Latitudes.

Since I'm cruising again after too long of a break I've decided I need to update and repost DrinkCalc, now at V.3.  
The math is the same but the interface and prices have been updated.
I was looking back at the comments and I'm thinking about integrating a selectable feature to not depreciate coffee and juice on port days for more accurate calculations.  I've also added two "misc" fields at the bottom for less common drink options.  The drink prices are also adjustable, but the new prices will reset to default whenever the page is reloaded due to lack of any persistent database function.
Both the calculator host and website host are also now free which means it won't be subject to price increases which is what killed the last version.
Enjoy, and please feel free to suggest improvements or let me know if you find any bugs.
Quick Edit:  The calculator now shows your average daily drink cost both with and without discounting coffee and juice on port days.  Admittedly it made more of a difference than I expected.  Cheers!

I made a spreadsheet to calculate my break even point for getting the Deluxe Beverage Package on an upcoming cruise.  It turned out to be pretty useful and I thought others might find it interesting.  So...  I made a site on Wix to host an online version of the calculator for anyone that might be interested.
DrinkCalc
DrinkCalc V.2  (Now prettier and hopefully easier to use.)
I'm open to feedback to improve it as needed.  Keep in mind the options for style are limited but I can tweak the math as much as I want.

I know how you feel.  I'm not sure if I should be relieved or concerned that I should definitely get my monies worth buying the drink package.

Fwiw, we were originally going to get my daughter certified and a refresher for me on our upcoming cruise.  After a little research about our local dive shops we found it was cheaper for my daughter to trained locally and I ended up getting my refresher free.  The deciding factors were the difficulty in planning our excursions when we didn't know when and where the open water dives would be, how much personal attention we would get during the classes, and whether my our certifying dives would be together.  She ended up certifying through SDI over about 2 months, as our schedules allowed, and found it very enjoyable and unhurried.  (She also finds it very amusing that she got her diving license before her friends got their driving licenses.)  As a result we now have 4 dives planned together thru local dive shops when we visit Roatan and Costa Maya.

$275 per person,and they only charge for the first rwo passengers. So, for three of us to go from a large balcony to JS was $550 total.

Alright, Drinkcalc V.2 is ready for testing.  The underlying math is identical but the interface is better due to it being through a different service.

I contacted special needs due to a allergy I have.  Here is the response they sent me...

Oh! If you want a rum drink, try a Dark & Stormy. Official drink of Bermuda but made everywhere nowadays. Just make sure it's made with Black Seal spiced rum and (if at all possible) ginger beer rather than ginger ale.

@JLMoran , Good thought.  I'll have to think about that. Ultimately it would be easier if it was a selectable option but I'm at the limit for usable fields with the level of calcapp I subscribe to.  I might be able to rig something in the background calculations.  As it stands it would probably be a blanket removal of the depreciation for coffee, juice, and water.  That would be easily done without needing another field.

The first one I can't do much about due the limitations in the service I'm using.  I'll need to find a more flexible standalone website builder that I can work with.  Maybe changing the input fields to the same style as the cruise length and port stays will make it easier to scroll.  I noticed that scrolling on my phone would routinely screw up the values I entered on the drink sliders.
The second one is done.  I changed the default to 33 and allowed selection of any whole number value between 0 and 100.
