How Much Do You Need to Retire? A Worked Estimate You Can Redo

The savings target is the last number in the sum. Don’t start there. Everything that sets it comes earlier: the spending, the income that arrives no matter what markets do, and the rate at which you are willing to draw down what is left.

Get those roughly right and the target follows in one line of division.

Step 1: What will you spend each year?

Start from what you spend now. A year of bank and card statements beats any rule of thumb about replacing a share of your salary, because it describes your own life.

Then adjust. Some costs stop at retirement, among them commuting, work clothes, payroll taxes on wages and the retirement contributions themselves, while others rise: health care almost always, travel and hobbies often, and home repairs as a house ages. A paid-off mortgage can remove the largest line of all.

Step 2: What does guaranteed income cover?

Guaranteed income arrives whether markets rise or fall. Social Security, a pension and an annuity you already own all count. Subtract it from spending. What remains is the gap your savings must fill.

The age you claim changes that figure a great deal, since benefits are reduced for claiming before full retirement age and increased for each year you wait past it, up to 70. The Social Security claiming calculator shows how much the gap shrinks if you delay.

A pension shrinks the gap further.

Check whether the pension rises with inflation. Social Security benefits receive a cost-of-living adjustment each year, set by the SSA. Many private pensions pay a fixed amount for life, and a fixed payment buys less every year, so the gap it leaves slowly widens as prices climb.

Step 3: Divide the gap by a withdrawal rate

The withdrawal rate is the share of savings you take out in the first year. Later withdrawals usually rise with inflation. Dividing the gap by that rate gives the savings needed.

Half a percentage point on the rate moves the target by about $107,000. Lower rates are the cautious choice. They leave more cushion for bad markets and long lives. They also need more savings.

The 4% figure comes from research on historical returns. The strategy page on the 4 percent rule covers where it holds up, where it breaks down, and why a lower rate is often suggested for long or early retirements.

Step 4: Add taxes back in

Traditional IRA and 401(k) money counts as ordinary income when it comes out. Spending $30,000 means withdrawing more than $30,000.

Add the expected tax to spending before you divide.

The $5,000 is a placeholder for the sum. Your real tax depends on filing status, the current brackets, how much of your Social Security becomes taxable and how the savings are split between traditional, Roth and taxable accounts, and those brackets are published by the IRS and change every year. Qualified Roth withdrawals are tax-free. They shrink the figure.

Step 5: Adjust for your circumstances

Age at retirement

Retiring early stretches the same savings over more years. It can also leave years before Social Security starts. The gap is wider then. Retiring later works the other way, with fewer years to fund, more years of saving and a larger benefit if you also delay claiming.

Health care before Medicare

Medicare eligibility starts at 65. If you stop work before then, you pay for health coverage yourself. Put that cost in the spending line for those years. Budget it separately, since it ends when Medicare begins. Premiums for coverage you buy yourself vary by age, state and plan. Get quotes for your own situation.

A longer or shorter retirement

A 35- or 40-year retirement needs a lower withdrawal rate than a 20-year one. That means a larger target. Your health, family history and a younger spouse all move the horizon.

Redo it every few years

The estimate is only as good as its inputs, and every input shifts over time, since spending changes, the Social Security statement updates with each year of earnings, and markets move the savings balance up and down.

Rerun the sum with fresh figures. The retirement withdrawal calculator takes your gap and rate and shows how long a balance lasts under different returns, and the free course on building a withdrawal plan starts with finding your retirement income gap and works through withdrawal rates, sequence risk and guaranteed income. Situations differ, so treat the result as a starting point for your own planning.
