Note
This is not financial advice. It is a simplified model: it applies the displayed standard formula to the figures you entered, assumes a single constant rate for every year, and ignores taxes, fees, sequence-of-returns risk, health costs, longevity risk and any country's specific pension, benefit or minimum-distribution rules. Real returns can be negative and real retirements rarely follow a smooth curve. Check the assumptions and consult a licensed adviser before acting on any figure.

What does the required nest egg calculate?+
It works backward from your desired annual retirement income and a chosen withdrawal rate to tell you the total portfolio size needed to sustain that income. It's the inverse of the safe withdrawal calculation: instead of income from a balance, it finds the balance needed for an income.
How does the withdrawal rate I choose change the target?+
A lower withdrawal rate produces a larger required nest egg because it spreads the same income over a smaller percentage of the portfolio (more conservative), while a higher rate lowers the target but assumes more risk of shortfall over a long retirement.
Should the income figure be before or after taxes?+
Use your desired after-tax spending power as the target if the calculator doesn't otherwise separate taxes, then account separately for taxes on withdrawals, since tax treatment differs by account type (401(k) withdrawals are taxed as income, Roth withdrawals typically aren't). Ignoring taxes will understate the true nest egg needed.
Does this number include Social Security or pension income?+
No — the calculator typically computes the nest egg needed to cover the income gap you specify, so if you plan to supplement retirement with Social Security, a pension, or part-time work, subtract that expected income from your target spending first.
Is a bigger nest egg always safer?+
Generally yes for portfolio survival, but an oversized target can mean working longer or saving more aggressively than necessary. It's worth balancing the estimate against your actual life expectancy, planned retirement age, and tolerance for adjusting spending later.
