can you try with something like this?

Forms\Components\TextInput::make('size')
  ->numeric()
  ->live()
  ->label('Altura'),
Forms\Components\TextInput::make('weight')
  ->label('Peso Kg.')
  ->numeric()
  ->live(debounce: 1500)
  ->afterStateUpdated(fn (Set $set, Get $get) => $set('imc', $get('weight') / ($get('size') * $get('size')))),
Forms\Components\TextInput::make('imc')
  ->label('Indice de masa corporal')
  ->live(),

Forms\Components\TextInput::make('size')
  ->numeric()
  ->live()
  ->label('Altura'),
Forms\Components\TextInput::make('weight')
  ->label('Peso Kg.')
  ->numeric()
  ->live(debounce: 1500)
  ->afterStateUpdated(fn (Set $set, Get $get) => $set('imc', $get('weight') / ($get('size') * $get('size')))),
Forms\Components\TextInput::make('imc')
  ->label('Indice de masa corporal')
  ->live(),

just replace * for + of course

thanks for your help, but the placeholder can't storage to database

Why do you need to storage to database? if you do calculations front-end someone can manipulate the value that is passing to database. For showing you can use placeholder, but to safe in database use a lifecycle hook : https://filamentphp.com/docs/3.x/panels/resources/editing-records#lifecycle-hooks
