Mega-Sena: quanto rendem R$ 8 milhões na poupança, Tesouro Direto ou CDB | CNN Brasil
Sorteio deste sábado (21) será realizado às 21h; apostas podem ser feitas até 20h
A Mega-Sena realiza neste sábado (21) o concurso 2987, com prêmio estimado em R$ 8 milhões.
A pedido do CNN Money, Michael Viriato, estrategista da Casa do Investidor, realizou um levantamento mostrando quanto rende uma aplicação do valor integral do prêmio, considerando o atual patamar da taxa básica de juros em 14,75%.
A poupança segue com o "menor" retorno, tanto no curto quanto no longo prazo: em um mês, a aplicação renderia pouco mais de R$ 53 mil e, após um ano, o ganho seria de R$ 652 mil.
A melhor opção estaria nos CDBs de bancos médios, considerando uma remuneração de 110% do CDI.
Neste caso, os mesmos R$ 8 milhões renderiam R$ 80 mil em apenas um mês e R$ 1 milhão em um ano.
O levantamento apresenta os ganhos em percentuais e em reais da poupança, do Tesouro Direto (considerado o título pós-fixado, o Tesouro Selic), CDBs e fundos DI, que acompanham o CDI e a taxa Selic.
As contas já consideram os rendimentos líquidos, ou seja, descontados do Imposto de Renda que incide sobre os ganhos. Apenas a poupança é livre de cobranças.
A simulação considera taxa de administração de 0,5% para os fundos DI e de 0,2% para Tesouro Selic, embora a cobrança varie entre fundos e corretoras.
O sorteio da Mega-Sena será realizado às 21h, no Espaço da Sorte, em São Paulo, e será transmitido ao vivo pelas redes sociais da Caixa.
