Laravel Sum each section using foreach

I have below table with data.

    ID - CLASS - CATEGORY - AMOUNT
    --------------------------------
     1    I       A          5000
     2    I       B          6000
     3    I       C          7000
     4    V       A          9000
     5    V       B          12000

now I want to sum the amount classwise in blade.php using foreach loop. like class I total is 18000, class V 21000 etc..

Controller Function:

   $viewRecords = YearlyFees::Where('registration_id',Auth::user()->id)->get();

    return view('yearly_fees_setup',
        ['viewRecords' => $viewRecords]);

Blade.php

     @foreach($viewRecords as $record)
                <tr>
                    <td></td>

                    <td>
                        
                    </td>
                    <td>
                    </td>
                </tr>
            <tr>
            <td> ?????? TOTAL of each class </td></tr>
            @endforeach

Result:

Class   Category          Amount
I       School Fees       5000
I       Tution Fees       6000
I       Library Fees      7000
                         **I WANT TOTAL HERE**
V       School Fees       9000
V       Tution Fees       12000
                         **I WANT TOTAL HERE**
