Almost every retirement plan comes down to two numbers: how much you will need, and how much to set aside now to get there. Everything else, the accounts, the investments, the claiming decisions, is detail hung on those two. The trouble is that both numbers sit decades away, so most people fly blind until the runway is short. You do not have to.
This guide walks the whole arc, from estimating the nest egg to drawing it down, and points you to the calculator behind each step so you can put your own figures in as you go.
Finding your retirement number
A common shortcut estimates your target as annual spending in retirement divided by a safe withdrawal rate, often 4 percent. Plan to spend $60,000 a year from savings and the math points to roughly $1.5 million. It is only a starting point, Social Security, a pension, or part-time work all lower the pile you need, but it turns a vague worry into a figure you can aim at.
The estimate improves as you refine two inputs: how much you will actually spend (often less than your working income once the mortgage and commute are gone) and how long the money must last (plan for a long life, not an average one).
The savings rate that gets you there
Time does most of the heavy lifting. A dollar saved in your twenties can be worth several times a dollar saved in your fifties, because it compounds for longer. That is why the single most powerful retirement move is starting early and letting the market work, even at a modest rate.
If starting early is not an option, the levers are a higher savings rate, working a little longer, or spending a little less in retirement. Small moves on each, combined, close surprisingly large gaps.
Accounts, and the order to fill them
Where you save matters almost as much as how much. A sensible order for most people: contribute enough to a 401(k) to get the full employer match, then fund a Roth or traditional IRA, then return to max the 401(k). The choice between Roth (taxed now, tax-free later) and traditional (deducted now, taxed later) hinges on whether your tax rate is likely higher today or in retirement.
Our Roth vs. Traditional and retirement accounts guide go deeper on that decision, which is worth getting roughly right rather than perfectly wrong.
The best retirement account is the one you actually fund, every paycheck, without thinking about it.
When to claim Social Security
Social Security is a guaranteed, inflation-adjusted income stream, and when you start it changes the check for life. Claim at 62 and the benefit is permanently reduced; wait past full retirement age and it grows about 8 percent a year until 70. The right age depends on your health, other income, and whether a spouse depends on the benefit.
Because claiming early means more checks but smaller ones, the decision turns on how long you expect to collect. The Social Security estimator and claiming optimizer show the trade-off in dollars for your situation.
Turning savings into a paycheck
The hardest part of retirement is not saving; it is spending down without running out. The 4 percent rule, withdrawing 4 percent of the starting balance and adjusting for inflation each year, is a durable starting point, but it is a guideline, not a guarantee. A weak market in your first few retirement years, called sequence risk, can force you to spend flexibly.
Your first-year income is roughly the balance times your withdrawal rate, divided by twelve. Staying flexible in down years, trimming a little rather than selling into a slump, is what makes a plan last thirty years.

Frequently asked questions
How much do I need to retire?
A rough target is your annual retirement spending divided by a safe withdrawal rate, often 4 percent, so $60,000 a year points to about $1.5 million. Social Security, pensions, or part-time income lower the amount you need to have saved.
What percentage of income should I save for retirement?
Many planners suggest around 15 percent of gross income, including any employer match, for someone who starts in their twenties or thirties. Starting later means saving a higher share or working a bit longer.
Is the 4 percent rule still safe?
It remains a widely used starting point, though some researchers favor a slightly lower rate for long retirements. Its biggest risk is a weak market early in retirement, which is why staying flexible with spending matters.
Should I use a Roth or traditional account?
Roth if you expect your tax rate to be higher in retirement, traditional if you expect it to be lower. Many people split the difference to hedge, since future tax rates are unknown.
When should I claim Social Security?
Waiting past full retirement age grows the benefit about 8 percent a year until 70, which pays off if you live long enough to collect it. Health, other income, and a spouse's needs all factor in.
