Income-multiplier Upgrades

These 140 upgrades contribute to a multiplier of the cookie income, which is the total output of all the buildings equipped with their respective upgrades. The income-multiplier upgrades are a mid-game to end-game feature because they become very expensive.

Flavored Cookies

Flavored cookies increase the base multiplier, which starts at 100%. These bonuses stack multiplicatively. Any multipliers from heavenly chips are treated in the same way as flavored cookies in that they are also added multiplicatively.

Template:Cookie upgrades

These 128 flavored cookies (without "Starlove" heavenly upgrade purchased) add up to:

$1.01^{7}\times 1.02^{51}\times 1.03^{20}\times 1.04^{40}\times 1.05\times 1.1^{9}\approx 63.192=6319.2\%$

When "Starlove" heavenly upgrade is purchased, the cookie production multiplier of 6 heart biscuits increases to 3% and the total multiplier goes to:

$1.01^{7}\times 1.02^{45}\times 1.03^{26}\times 1.04^{40}\times 1.05\times 1.1^{9}\approx 67.001=6700.1\%$

Kitten Upgrades

Each kitten upgrade boosts the CpS multiplier by a percentage proportionate to the Milk amount and each upgrade's effect stacks with another multiplicatively. For example:

Kitten helpers boost the CpS by 10% of the Milk amount. So with a Milk level of 150%, Kitten helpers will boost CpS by 1 + 0.1 × 1.5 = 1.15 = 115%
Kitten workers boost the CpS by 12.5% of the Milk amount. With a Milk level of 150%, Kitten workers will boost CpS by 1 + 0.125 × 1.5 = 1.1875 = 118.75%
With both Kitten helpers and Kitten workers upgrades, CpS will be multiplied by 1.15 × 1.1875 = 1.365625 = 136.5625%

See Milk for more details.

Bingo Center/Research Facility

After you have the elder achievement and own at least 7 grandmas you are eligible to get the "Bingo Center/Research Facility", which costs 1 quadrillion cookies (as of version 2). After you purchase it, it will research an upgrade with each research period taking 30 minutes without "Persistent memory" heavenly upgrade and 3 minutes with it. HOWEVER: research time is based on frames, not minutes. The game naturally runs at 30fps. If you alter that to 5fps to reduce load on your CPU, upgrades will then take 3 hours. At 10fps they take 1 hour 30 minutes, at 20fps they take 45 minutes, and so on. Research on the next upgrade will not begin until the previously researched item has been purchased.

If you want "Sacrificial rolling pins" without waiting, you can buy "Elder Pledge", then "Elder Covenant", then "Revoke Elder Covenant", then repeat until you've unlocked the upgrade.

Once Elder pledge is maxed out, you should buy the sacrificial rolling pins and keep using the pledge. Because the rewards from golden cookies are CPS reliant the elder covenant is never worth it. Until 3.9*10^9 CPS the wrath cookies (red cookies) are the best because of the increased chance on getting a cookie chain. From 3.9* 10^9 CPS onward pledge is the best option.
If you are actively playing, enabling the Elder Pledge or Elder Covenant will remove the wrath cookies and their bad outcomes; if you have all of the golden cookie upgrades this will pay off for sure. But if you're not going to play for a good while (i.e. letting it idle overnight, or preferably a weekend) there's no benefit from pre-buying the Pledge or leaving the Covenant enabled, unless you want the Sacrificial Rolling Pins in the case of the former. Also, the wrinklers which spawn when you do not have the Pledge/Covenant enabled greatly decrease your CPS.
However, be careful that revoking the Covenant and then re-declaring it too soon doesn't covertly eat into your overall CpS. At the 3.05*10^9 CpS breakpoint where Pledge and Covenant cost about the same, it may initially seem that you need just 37 minutes of idling to produce the cookies required to re-declare the Covenant after breaking it... but actually, it takes nearly 12 hours for the 5.26% bonus from breaking the Covenant to pay off. It takes longer still if your idle CpS is lower, or you haven't upgraded to Sacrificial Rolling Pins - potentially 24 hours or (much!) more. There still is no "intrinsic" bonus from leaving the Covenant in place, but by doing so you avoid the 66.67 trillion overall cost of breaking and re-declaring it, which can itself be very valuable. (Mind that there is no such hidden downside to not buying an additional Pledge - unless you are angling for the "Upgrader" achievement - as they remain a one-shot "upgrade" at all levels). However you should not buy the Covenant except for the achievement or if you are too lazy to click the elder pledge every hour.
Note that as of v1.037 (beta), the price cap for the Elder Pledge increases eight-fold, to about 4 trillion cookies; this will of course impact on the calculations above and whether you are better off buying the Covenant or not. EG the "3.05 Gcps breakpoint" will shift upwards to about 24.4 Gcps instead, or approximately the idle production level of a no-reset, 100 Antimatter Condenser endgame.

Notes

↑ Purchasing the One Mind upgrade triggers the beginning of the Grandmapocalypse.
↑ The price of Elder Pledge goes up to 4.398 trillion or 8¹⁴ (or, 2⁴²), and increases by 8x (2³) each time. Elder Pledge does not show up in the Upgrades list. Elder Pledge is not availble when Elder Covenant is in effect.
↑ ^3.0 ^3.1 The Elder Covenant and its reversion Revoke Elder Covenant can be repeatedly purchased. The "Revoke" upgrade appears in the cookie Store when the Elder Covenant is purchased and vice versa. This is not a toggleable upgrade in any conventional sense - and would be better considered "reversible" - as a change in state must be purchased each time whereas "toggling" normally refers to a single on-off switch function. Note that, at least as of v1.035, the 5% of CpS is literally that - with the Covenant in place, your overall cookie production rate, inclusive of all other bonuses and multipliers, falls to 0.95x what it would have been before. Revoking it therefore actually grants you an extra 1/19th cookies, or a 5.26% bonus to CpS.
↑ The price of each season switch is twice the last. Unlike the Elder Pledge, this is not capped and will eventually exceed a day's production.
↑ ^5.0 ^5.1 ^5.2 Once this upgrade is unlocked, it will be unlocked across the ascension.
↑ ^6.0 ^6.1 ^6.2 At least one golden cookie click in the current game is needed before the all-time number will be counted for the criteria of upgrades.
↑ The price of all Santa upgrades you haven't purchased yet triples each time you upgrade Santa.
↑ ^8.0 ^8.1 ^8.2 Upgrades which lower the cost of upgrades stack multiplicatively, not additively. That is, if you have 3 of them which reduce the cost of upgrades by 5%, 2% and 1% then the final cost of an upgrade is (original cost) * 0.95 * 0.98 * 0.99.
↑ The price of each common egg doubles each time you buy an egg.
↑ The price of each rare egg triples each time you buy an egg.

The 1.037 beta has the same upgrades as the previous version.
Note that upgrades can be cheaper via "Toy workshop" (-5% to all upgrades prices), "Santa's dominion" (-2%) and "Faberge egg" (-1%) upgrades or "Five-finger discount" (-1% per every 100 Cursors bought), "Divine sales" (-1%) and "Divine bakeries" (-80% to flavored cookies) heavenly upgrades or "Master of the Armory" dragon aura (-2%).

The description of the upgrade Jaffa Cakes is a reference to a product of the same name introduced by the company McVitie's, and is a reference to Carl Sagan's quote "If you wish to make an apple pie from scratch, you must first invent the universe" from his book Cosmos. It could also be a reference to the YouTube channel "The Yogscast" where in a modded version of Minecraft called Tekkit, they created a factory to automatically make jaffa cakes.

The Weighted Sleighs upgrade's flavor text may possibly be a reference to a saying from Gabe Newell.
It seems like even with upgrades that make other upgrades cheaper, you still need the original amount of cookies for upgrades to light up. This is only a visual bug, and you can still buy the upgrade even if it isn't brightened.
When holding your cursor in the store and moving it quickly over the tooltip of an upgrade, the store window will minimize.
The flavor text for the Christmas upgrade 'Increased merriness' ,'The s'more the merrier', is a play on the quote, "The more the merrier". A s'more is a roasted marshmallow sandwiched between two graham crackers.

The Prism upgrade Pure Cosmic Light was the only main building final upgrade to not have a blue sparkle in its sprite as of V1.0411 (fixed in 1.0418).
The flavor text for the prism upgrade Grainbow, "Remember the different grains using the handy Roy G. Biv mnemonic" refers to the mnemonic Roy G. Biv, which actually is used to remember the seven colors of the rainbow.
Вefore 1.0420, season updates couldn't be bought twice in a row (i.e. once the 24 hours are over, it becomes locked again, so you need to buy a different season before you can buy this one again).
Starting with the version 2, base cost of "Licorice macarons" upgrade increased 10 million times, from 1 quintillion to 10 septillion, which makes it most significant upgrade cost increase both in absolute and relative numbers at the moment. Next cost increase in absolute numbers to consider is "Brane transplant" — from 1.667 trillion to 5 quintillion (cost of efficiency increase upgrades for buildings is calculated based on building base price and tier multiplier common for all building types).
The flavor text for Bunny biscuit is a reference to Watership Down's El-Ahrairah being blessed with being hard to catch.
The flavor text for Duck Egg is a reference to the song, video, and book 'The Duck Song.'
The flavor text for Robin Egg is a reference to the superhero Robin from the 1960s Batman TV show as he would often make exclamations following the same format.
The flavor text for Salmon roe is a reference to the song 'Libera me from hell' from the anime 'Tengen Toppa Gurren Lagann.'
The flavor text for Omelette "Omelette du fromage" is a reference to an episode of the cartoon show 'Dexter's Laboratory', when the main character (Dexter) repeats the same phrase over and over again.
The "Aqua crustulae" upgrade name means "Water of cookie" in Latin, although in proper grammar this would be "Aqua crustuli" or "Aqua crustulorum". It's probably is a reference to Latin expression "Aqua vitae" that means "Water of life".
The "Ardent heart biscuits" upgrade's flavor text probably have a reference to Red Hot Chili Peppers band.
The "egg" bears a strong resemblance to Yoshi's eggs from Super Mario World, a normal Pokémon egg from the game series "Pokémon" and a spawn egg from Minecraft. Orteil said that there is no reference in any of it.
The flavor text for "Shark Egg" is a reference to the scene in Finding Nemo where a group of sharks is swearing off fish, trying to remain vegan, saying "Fish are friends, not food!"
The tiers of the building upgrades are named in the source code:
- Plain, these upgrades have no specific colour associated with them
- Berrylium, pun on Beryllium and Berry
- Blueberrylium, pun on Beryllium and Blueberry
- Chalcedhoney, pun on Chalcedony and Honey
- Buttergold, pun on Butter and Gold
- Sugarmuck, pun on Sugar and Muck(?)
- Jetmint, pun on Jet and Spearmint
- Cherrysilver, pun on Cherry and Silver
- Hazelrald, pun on Hazel and Emerald (commented out/not in use) (only shown with cursor and mouse upgrades)
- Mooncandy, pun on Moonstone and Candy (commented out/not in use) (only shown with Sextillion Fingers, Septillion Fingers and Octillion Fingers)
If you look at the upgrades in the Stats screen after they are purchased, they will all say "[Purchased]". However, the kitten upgrades will say "[Purrchased]".
Version 2 changed quite a few upgrades:
- All upgrades that "added x base CpS" to the buildings were changed to another "doubles efficiency" upgrade, which was a buff because the base CpS increase was less than the original base CpS, and each upgrade stacks with all others (except the doubling efficiency of cursors and their -illion fingers)
- Every -illion fingers upgrade for the cursors except "thousand fingers" and (maybe) "million fingers" were buffed, so now all of them except "thousand fingers" add 5x10^x cookies per cursor. "Octillion fingers" now gives 5 million CpS per cursor instead of around 200,000 (needs correction).
- As stated above, Persistent Memory is no longer an actual upgrade, but now a legacy upgrade, costing 5 heavenly chips.
- Upgrades that add to the cookie production multiplier (i.e. Santa's Dominion adds +20% cookie production) were buffed to be global, so the percentages were reduced. Cookie upgrades that added +5% made the percentage, for example, go from 1,000% go up to 1,005% production. Now, those +5% cookie upgrades give +1% cookie production, and would boost the percentage from 1,000% to 1,010%.
- The description of certain research upgrades were changed to match how they really act. One Mind, for example, originally said "grandmas gain +1 base CpS per 50 grandmas," implying you may need to get 50 grandmas for a CpS boost. Now, it says "grandmas gain +0.02 CpS per grandma," showing that each grandma boosts every other grandma by 0.02 base CpS, instead of requiring 50 to get the boost.
- Some cookies/biscuits (i.e. Macarons) now require a Heavenly Upgrade to purchase.
The Cookie Upgrade "Pecan Sandies" flavor text is a reference to the It's Always Sunny In Philadelphia Season 3 Episode 9 "Sweet Dee's Dating a Retarded Person" where Frank wants the band to be called "The Pecan Sandies"
