Accumulation has one job: build the balance. Retirement income is harder. Which account do you draw from, in what order, at what tax cost, while timing Social Security and staying under the thresholds that raise your Medicare premiums. Done well, the same portfolio supports a higher, steadier income for longer.
Building the balance is the straightforward part: save, invest, stay diversified, wait. Turning that balance into income is harder. You have to decide which account funds which years, in what order, at what tax cost, while timing Social Security and staying under the income thresholds that raise your Medicare premiums. Done deliberately, the same portfolio supports a higher, steadier income for longer.
Two retirements can see the same average return and end very differently, because the order of returns is not the same. A sharp market drop in the first year of retirement, while you are withdrawing, does damage that the same drop in year fifteen does not. A retirement income plan holds enough in stable assets that a bad market does not force selling at the bottom. More on the risks we look at first.
A written income plan: year by year, which account, how much, and what it does to your tax bracket and your Medicare premium. It is one part of the broader financial plan, reviewed every year and after any major change, so it reflects the retirement you are actually in.
The 4% rule is a starting reference point, not a plan. It says a retiree can withdraw about 4% of the starting balance, adjusted for inflation, with a low chance of running out over 30 years. A real plan adjusts each year to actual markets, taxes, spending, and how long the money needs to last, which usually lets you spend more in good years and protects you in bad ones.
As a default, taxable accounts first, then traditional IRA and 401(k), then Roth. That order is bent in practice around Roth conversion years, IRMAA income thresholds, and what you want to leave to heirs. The sequencing decision has a large effect on your lifetime tax bill and how long the portfolio lasts.
For most people with the resources to wait, claiming closer to 70 produces the largest inflation-adjusted lifetime benefit, because the benefit grows for each year you delay past full retirement age. Married couples coordinate two claiming ages and the survivor benefit, which makes it more than a single breakeven calculation.
By building the plan around the risks, not just the average return. That means holding enough in stable assets that a bad market early in retirement does not force selling at a loss, sequencing withdrawals to control taxes, and revisiting the plan every year against what actually happened. The goal is an income that stays steady across a full retirement, in real terms.
