## HackingFormulas.growAmount() method
|
||||
|
||||
Calculate the amount of money a grow action will leave a server with. Starting money is server.moneyAvailable. Note that when simulating the effect of [grow](./bitburner.ns.grow.md)<!-- -->, what matters is the state of the server and player when the grow \*finishes\*, not when it is started.
|
||||
|
||||
The growth amount depends both linearly \*and\* exponentially on threads; see [grow](./bitburner.ns.grow.md) for more details.
|
||||
|
||||
The inverse of this function is [formulas.hacking.growThreads](./bitburner.hackingformulas.growthreads.md)<!-- -->, although it rounds up to integer threads.

|

| Parameter | Type | Description |
|
||||
| --- | --- | --- |
|
||||
| server | [Server](./bitburner.server.md) | Server info, typically from [getServer](./bitburner.ns.getserver.md) |
|
||||
| player | [Person](./bitburner.person.md) | Player info, typically from [getPlayer](./bitburner.ns.getplayer.md) |
|
||||
| threads | number | Number of threads to grow with. Can be fractional. |
|
||||
| cores | number | _(Optional)_ Number of cores on the computer that will execute grow. |
|
||||
|
||||
**Returns:**
|
||||
|
||||
number
|
||||
|
||||
The amount of money after the calculated grow.

|
||||
|
||||
## HackingFormulas.growPercent() method
|
||||
|
||||
Calculate the percent a server would grow to. Not exact due to limitations of mathematics. (Ex: 3.0 would grow the server to 300% of its current value.)
|
||||
Calculate the growth multiplier constant for a given server and threads.
|
||||
|
||||
The actual amount of money grown depends both linearly \*and\* exponentially on threads; this is only giving the exponential part that is used for the multiplier. See [grow](./bitburner.ns.grow.md) for more details.
|
||||
|
||||
As a result of the above, this multiplier does \*not\* depend on the amount of money on the server. Changing server.moneyAvailable and server.moneyMax will have no effect.
|
||||
|
||||
For the most common use-cases, you probably want either [formulas.hacking.growThreads](./bitburner.hackingformulas.growthreads.md) or [formulas.hacking.growAmount](./bitburner.hackingformulas.growamount.md) instead.
