You are contributing 10.0% of salary, using a 22.0% estimated marginal federal tax rate, over 30 years at a 7.0% annual return.
What does this result mean?
Your projected balance combines your current balance, the annual contribution calculated from your salary, and the return assumption you entered. It does not predict what the market will do. It shows how powerful steady contributions and compounding can be under one simple scenario.
The tax-savings estimate applies your selected marginal federal tax rate to your pre-tax contribution. Your actual tax result can differ because of deductions, credits, payroll withholding, state taxes, and other income.
Methodology and assumptions
- Annual contribution = salary × contribution rate, capped at the current employee limit.
- Projected balance compounds once per year, with contributions added at the end of each year.
- Return and tax-rate inputs are assumptions you control; Gleefund does not recommend them.
- The estimate excludes employer matching, inflation, investment fees, market volatility, and state income tax.
- The active policy set is labeled 2026 and must be checked against the IRS when annual limits change.
Frequently asked questions
How much should I contribute to my 401(k)?
A common starting point is enough to receive the full employer match, if your plan offers one. Your own target depends on your income, goals, current savings, and other priorities.
What is the 401(k) contribution limit?
The active Gleefund data layer currently uses a 2026 employee deferral limit of $24,500 and a catch-up amount of $8,000.00 for eligible participants age 50 or older. Under SECURE 2.0, participants ages 60-63 may use a higher catch-up of $11,250. Verify current limits with the IRS before acting.
Does contributing to a 401(k) reduce my taxes?
Traditional pre-tax contributions can reduce taxable income, but the actual impact depends on your tax situation. Roth 401(k) contributions are taxed differently and are not represented by this simplified estimate.
