## HackingFormulas.growThreads() method

Calculate how many threads it will take to grow server to targetMoney. 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.growAmount](./bitburner.hackingformulas.growamount.md)<!-- -->, although it can work with fractional threads.

**Signature:**

```typescript
growThreads(server: Server, player: Person, targetMoney: number, cores?: number): number;
```

## Parameters

|  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) |
|  targetMoney | number | Desired final money, capped to server's moneyMax |
|  cores | number | _(Optional)_ Number of cores on the computer that will execute grow. |

**Returns:**

number

The calculated grow threads as an integer, rounded up.
