One option is to use a getter which is just a method that returns the value of a property

i basicly use a trait to get alot of price information from the database. I would like to return the prices from the trait so i can use them in a controller.

i'm not quite sure how your trait looks like, is the first code block the trait method ?

you can create a getContractValueAttribute method on your BuiOreContractContents model:

public function getContractValueAttribute()
{
    // return calculated value
}

usage

$oreContract->ContractValue //returns calculated value

Here is the first code block for the trait.

trait Contracts
{
    use Prices;

    public function OreContract(Request $request)
    {
        $update = BuiOrePrices::orderBy('created_at', 'desc')->first();
        $lastContractNum = BuiContracts::max('ContractNum');

        $oreContract = new BuiOreContractContents();
        
        $ContractNum = $lastContractNum + 1;
        $oreContract->ContractNum = $ContractNum;
        $oreContract->QuoteTime = $update['created_at'];

        if($request['Veldspar_units'])
            {$oreContract->Veldspar = $request['Veldspar_units'];} else {$oreContract->Veldspar = '0';}

Prices is another trait i've setup to pull prices from the database. Hopefully this helps a bit
