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. **Signature:** ```typescript growAmount(server: Server, player: Person, threads: 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) | | 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.
