O Match do Empregador

Se o empregador iguala 100% dos primeiros 3% e 50% dos próximos 2%: contribuir 5% de $80.000 ($4.000/ano) gera $3.200 de match — 80% de retorno IMEDIATO. 25% dos empregados não contribuem o suficiente para o match completo — bilhões em dinheiro grátis perdidos.

Equivalente no Brasil

O equivalente brasileiro é a previdência privada (PGBL/VGBL). O PGBL permite deduzir até 12% da renda bruta no IRPF. Algumas empresas oferecem previdência corporativa com match — sempre contribua o suficiente para capturar 100% do match.

⚡ CalcWolf Insight

The 2025 401k contribution limit is $23,500 ($31,000 for age 50+). If you max it out for 30 years at 8% returns, your 401k alone grows to $2.95 million. Even if you start maxing at age 35 (25 years), you reach $1.95 million. The 401k is the single most powerful wealth-building tool available to most Americans.
