Retirement Income & Spending
Retirement income is the combination of Social Security, pensions, and withdrawals from taxable, traditional, and Roth accounts. Spending is what remains after you separate essential costs from discretionary ones. The planning question is how long that mix can last under assumptions you can change.
How much income and how much spending
How much you can spend depends on the income that does not come from the portfolio, the withdrawals that do, taxes, and how long the retirement might last. A rule of thumb can start the conversation. It is not a guarantee that a portfolio will survive a bad sequence of returns.
Essential spending and discretionary spending do not have to move together. Cash reserves can cover a short period without selling investments after a decline. Inflation changes what a fixed withdrawal buys later.
Withdrawal sequencing
The account you draw from changes taxable income, future required distributions, and sometimes Medicare premiums. Taxable brokerage withdrawals, traditional IRA and 401(k) withdrawals, and Roth withdrawals are not interchangeable. Social Security timing changes how large those withdrawals need to be in the bridge years.
Portfolio longevity is an estimate under the returns, spending, and lifespan you assume. RetirementNeuron keeps that estimate separate from the written explanation of why it matters.
