Upgrading System Numbers

I am making a simulator where you can upgrade the multiplier for how much of a currency you get.

I need good numbers for how much more it will cost each upgrade, and how much it will give next upgrade.

Example:

-- when player buys:
cost = cost * 1.1 -- this is how much the next upgrade will cost
multi = multi * 2 -- this is what multiplier the next upgrade will give

I’m confused what your question is?
What exactly is the problem you need to solve?

I need suggestions for how the cost of an upgrade will change each time the player purchases it, and how much (and if) the multiplier will change.
Example:
Cost: 100, multiplier 1 → 2
Player buys,
Now the cost is 1.1 of the original and multiplier is 2x the original so Cost: 110, multiplier 2 → 4
Next would be Cost: 121, multiplier 4 → 8 etc.
I just need numbers for how much it changes by right now the cost is multiplied by 1.1 per purchase and multiplier is by 2.

I meant like what multiplier to use; the 2, and 1.1 are examples

Sorry, I had to correct this one

Multiplier:
1-2-4-8-16-32-64-128-256-512-1024 and so on

Cost:
100-110-121-133.1-146.41-161.051 and so on,

maybe use a calculator to do it?

A good way is to make the cost somewhat bigger than the multiplier, maybe 2.5 for the cost and 2 for the multiplier? Then make a rebirth/extra upgrades which give you an additional multiplier.
