Planet Clicker Upgrades: Every Generator, Price and Output

Everything you buy in Planet Clicker comes from the shop, which you open with the button in the bottom right corner. Each planet has its own list. There are two kinds of upgrade: one clicker upgrade per planet, which multiplies your click power on that planet, and generators, which add a fixed amount of energy per second. The figures below come from the upgrade lists inside the game's Scratch project.

Generators

Planet	Generator	First price	Adds	Seconds to pay back the first one
Earth	Campfire	100	1/s	100
Earth	Farm	800	10/s	80
Earth	Animal farm	10,000	120/s	83
Earth	Windmill	75,000	1,000/s	75
Earth	Factory	250,000	5,000/s	50
Mars	Solar panels	250,000	8,000/s	31
Mars	Oil mine	3 million	75,000/s	40
Mars	Coal power plant	40 million	1 million/s	40
Mars	Nuclear power plant	500 million	20 million/s	25
Mars	Alien technology	8 billion	500 million/s	16
Venus	Iron mine	250 billion	1 billion/s	250
Venus	Lava power plant	3 trillion	20 billion/s	150
Venus	Future technology	80 trillion	1 trillion/s	80

Every time you buy a generator, its next price goes up by 15%. Each generator can be bought up to 1,000 times; after that the shop shows "maxed". The payback column is just price divided by output for the first copy, so it gets longer with every copy you add.

Clicker upgrades

Upgrade	First price	Effect	Price growth	Max
Earth clicker	20	x2 Earth click power	x3 per buy	10
Mars clicker	100,000	x4 Mars click power	x6 per buy	10
Venus clicker	100 billion	x8 Venus click power	x12 per buy	10

The clicker upgrades multiply, they do not add. Ten Earth clicker upgrades take Earth from 1 to 1,024 energy per click and cost 590,480 energy in total. Click power only applies on the planet the upgrade belongs to.

What the numbers mean for buying

• On Earth, the factory is the best value per energy spent. Its first copy pays for itself in 50 seconds, faster than any other Earth generator. The campfire is the slowest.
• Mars generators beat Earth ones. Solar panels cost the same as a factory but add 8,000/s instead of 5,000/s. Further up the list, alien technology pays back fastest of anything in the game.
• Venus generators are slow to repay at first. An iron mine needs 250 seconds to return its price. They are still the only way to add billions and trillions per second, so they matter once you are on Venus.
• Cheap Earth clicker upgrades help at the very start. The first few cost 20, 60 and 180, so they double your click several times before you can afford much else.
• Compare after a few copies. Because of the 15% price rise, a generator you have bought many times can become worse value than the next one up the list. Check the price shown on each "buy" button.

Energy per second is one shared total, so generators on every planet add to the same balance no matter which planet you are viewing.
