Will Your Retirement Income Last?

The retirement question that actually matters

Most retirement anxiety comes from not knowing one number: will your savings produce enough income to last? This calculator projects your nest egg to your retirement age, applies the widely-used 4% withdrawal guideline to estimate sustainable annual income, adds your pension or Social Security, and compares it to the income you actually want.

The result tells you whether you're on track or facing a gap — and seeing a gap early, while you still have years to act, is the whole point. Small changes today (a higher contribution, a few more working years, a more efficient withdrawal strategy) compound into large differences by retirement.

Understanding your retirement income estimate

RetireGauge is built to help you picture whether the money you have set aside will keep paying you a paycheck once your working income stops. Retirement planning can feel abstract, so this tool turns a few familiar numbers into a single, plain-language read on how long your savings might last. Use it as a conversation starter, not a final verdict.

How this retirement estimate works

The calculation begins with what you tell it. You enter your current savings, the contributions you expect to keep adding each year, an expected average annual return on your invested balance, and a withdrawal rate that represents how much you plan to draw down once you retire. From there the tool projects your balance forward, applies your withdrawals, and gauges whether your income is likely to hold up across a long retirement or run dry early. Changing any single input shows you how sensitive your outcome is. A slightly higher savings rate, a more modest spending target, or a few extra working years can move the result meaningfully, which is exactly why it helps to test several scenarios rather than trust one.

What the 4% rule assumes

The withdrawal rate sits at the center of every retirement projection, and the widely cited 4% rule is the common starting point. It assumes roughly a 30-year retirement horizon and leans on historical market returns to suggest that withdrawing about 4% of your portfolio in the first year, then adjusting for inflation, has a reasonable chance of lasting. Treat that as a guideline, not a guarantee. Real markets do not deliver smooth average returns. Sequence-of-returns risk, the danger of poor returns landing in your first retirement years while you are also withdrawing, can shorten how long a portfolio survives even when the long-run average looks fine. A shorter horizon, higher spending, or a rough early stretch may call for a more conservative withdrawal rate, while a flexible budget gives you room to adapt.

Income beyond your savings

Your portfolio rarely has to carry the full load on its own. Social Security benefits, an employer pension, or an annuity can each provide steady income that reduces how much your invested savings must produce every year. Even a modest guaranteed stream lowers your effective withdrawal rate and eases sequence-of-returns pressure, because you are pulling less from the market during downturns. Because these sources matter so much, it is worth getting real figures rather than guessing. You can check your personalized benefit estimate from the Social Security Administration at SSA.gov, and confirm any pension or annuity details with the plan provider, then fold those numbers into your own planning.
