Sobre esta ferramenta

Enter your salary, your contribution and your employer match as a percent of pay, your current balance, years to retirement, expected return and yearly pay raise. The calculator adds contributions each year and compounds the balance to show the total at retirement. Figures are for the 2026 tax year and can change. A guide only, check irs.gov or a tax professional.

How it is calculated

Each year the tool adds your contribution and the employer match, both as a share of that year's pay, and grows the balance by the expected return. Pay rises by the raise rate each year. Contributions are assumed to arrive evenly through the year.

Example

On $80,000, with 8 percent saved and a 4 percent match, a $20,000 start and 7 percent return, the balance after 30 years is above $1.6 million, before inflation.

Limits and tips

The 2026 employee deferral limit is $24,500, with extra catch-up contributions from age 50. Always capture the full employer match first, because it is an immediate return. Results are in future dollars and inflation reduces what they buy.

Exemplo prático

With the boxes at their starting values (Current yearly salary ($): 80000; Your contribution (% of pay): 8; Employer match (% of pay): 4; Current balance ($): 20000; Years until retirement: 30; Expected return per year (%): 7), the tool shows: Your contributions ($): 304,483; Employer contributions ($): 152,241; Investment growth ($): 963,473; Total saved in the first year ($): 9,600; Projected balance ($): 1,440,197.

Dicas para melhores resultados

Confira cada campo antes de confiar em um resultado, porque um dígito errado muda a resposta inteira. Use os valores exatos do seu holerite, conta, certificado ou contrato e anote a data em que calculou. Alíquotas, limites e regras mudam de tempos em tempos, então em impostos, taxas e assuntos legais trate o resultado como estimativa e confirme com a fonte oficial indicada nesta página. Você pode testar quantos cenários quiser; nada é guardado nem enviado, e atualizar a página limpa os campos.
