# Why Your 401(k) Statement Shows a Monthly 'Paycheck' — and Why the Number Can Feel So Small
Your 401(k) provider calculates what your balance could generate each month if you withdrew it steadily over your retirement years. This projection appears on your statement as a "paycheck" or "monthly income estimate" to help you visualize retirement spending power.
The number often shocks people. A $500,000 balance might show a monthly income of just $1,800 or $2,000. The math behind this deflation is straightforward. Brokers typically divide your total balance by 300 months, assuming a 25-year retirement starting at age 65. They also factor in conservative investment returns, inflation adjustments, and fees that eat into gains.
Vanguard, Fidelity, and Charles Schwab all display these estimates differently. Vanguard uses a modest 4% withdrawal assumption. Fidelity applies more aggressive return projections. Schwab calculates based on your current asset allocation. Read your statement's fine print to understand which assumptions your plan uses.
The paycheck estimate serves a real purpose. It forces you to confront a hard reality early: your current savings rate may not support the lifestyle you imagine. A 30-year-old contributing $200 monthly to a 401(k) earning 5% annually will accumulate roughly $400,000 by 65. At conservative withdrawal rates, that generates $1,300 monthly.
Don't treat this number as gospel. It reflects worst-case assumptions. If you earn 6% instead of 4%, your income stretches further. If you work two extra years, your balance jumps significantly. If you spend less than expected, your money lasts longer.
Use the estimate as a starting point for honest conversation with yourself.
