A financial tool is employed to project potential retirement savings outcomes under two distinct 401(k) plan types: Roth and traditional. It requires inputs such as current age, salary, contribution rate, estimated rate of return, and tax bracket information to model future account values and tax liabilities in retirement. For example, an individual could use such a tool to compare estimated after-tax retirement income from contributing $10,000 annually to either a Roth or traditional 401(k) over a 30-year period, factoring in projected tax rates.
This instrument offers valuable insights for retirement planning. It aids in making informed decisions about which type of 401(k) plan may be more advantageous based on individual financial circumstances and expectations regarding future tax rates. Historically, individuals considered traditional 401(k)s more suitable when expecting to be in a lower tax bracket during retirement, while Roth 401(k)s were favored when anticipating higher retirement tax rates. The tool helps to quantify these potential differences.
