This doodad will help you determine how many unit-producing structures your bases can support.
Choose the mixture of units spawned from your larvae. For example, (D=1, Z=2) would mean that you spawn drones and twice as many zergling. Only the ratio of units is relevant, so (D=4, Z=8) is exactly the same as (D=1, Z=2). For units that are morphed from other units (Baneling, Brood Lords and Overseers), the cost of the original unit is included (for example, the cost of a Baneling would be 50 mineral and 25 gas).
N.B. You don't have to add Zergling if you want to spawn Baneling.

With this distribution, your income will be ? minerals per second and ? gas per second. You can find the math behind the income per Drone in this article.
In addition, your bases will spawn a larva every ? seconds.
Below is the amount of resources used to produce your army, assuming that all buildings are continually producing units.
What this means is that continually producing units from all buildings costs ? than your bases will produce.
There are additional places to sink your resources into, such as new buildings, expansions and upgrades, which will limit the amount of resources available for growing your army. It's also quite alright if the percentage of resources you can spend exceeds 100%. In many circumstances, buildings may be idle for short periods. It's usually better to have a bit too much production capacity.
N.B. All calculations above assume the game speed is set to Normal. On Faster speed, which is common for ladder games, everything is 21% faster. You mine 21% more per second, and you produce units 21% faster. For the purpose of comparing the resources mined to the resources spent, this balances out.
If you were able to afford continually producing units from all larvae, you would produce:
