Plan your future with confidence. Project your nest egg, estimate retirement income, and find out exactly how much you need to retire comfortably.
Retirement planning can feel overwhelming, but it comes down to a few key numbers: how much you've saved, how much you add, how long your money grows, and how much you'll need. Our retirement calculators turn those numbers into a clear picture — so you can see if you're on track and adjust while there's still time.
Project your nest egg at retirement, estimate your annual income using the 4% rule, and see if you're on track. Includes a growth chart and personalized verdict.

RelatedThe scariest thing about retirement isn't the math — it's not knowing whether you're doing enough. A retirement calculator removes that uncertainty. By projecting your savings forward and comparing them to your goals, it tells you clearly whether you're on track, ahead, or need to save more.
It also reveals the power of small changes. Bumping your monthly contribution by even $100, or starting a few years earlier, can add hundreds of thousands to your final nest egg. Seeing those numbers is often the motivation people need to take action today.
| Annual Spending | Target Nest Egg (×25) | 4% Income |
|---|---|---|
| $40,000 | $1,000,000 | $40,000/yr |
| $60,000 | $1,500,000 | $60,000/yr |
| $80,000 | $2,000,000 | $80,000/yr |
| $100,000 | $2,500,000 | $100,000/yr |

The calculator focuses on your personal savings and investments. Social Security and pensions are separate income sources that supplement your nest egg, so your total retirement income will typically be higher. Check your estimated Social Security benefit at ssa.gov.
Projections are estimates based on the return rate you enter, which isn't guaranteed. Real markets fluctuate. Use conservative assumptions and treat the results as a planning guide, not a promise. For a personalized plan, consult a licensed financial advisor.
When you start. Compound growth rewards time more than amount, so ten early years frequently outweigh twenty later ones at the same monthly contribution. Contributions can be raised later; the years cannot be recovered, which is the argument for starting with whatever is currently possible.

Open Retirement Calculator →Retirement planning is unusual among financial tasks because the horizon is measured in decades, which makes compound growth the dominant factor and makes small early decisions disproportionately important. Someone starting at twenty-five with a modest contribution frequently ends up ahead of someone starting at forty with a much larger one.
The other defining feature is uncertainty. Nobody knows what returns markets will deliver, what inflation will do, or how long they will live. A projection is not a forecast; it is a statement of what follows from a set of assumptions. Running several scenarios is considerably more informative than running one.
| Concept | What It Means | Rough Guide |
|---|---|---|
| Rule of 25 | Target nest egg for your spending | 25 x expected annual expenses |
| The 4% rule | Sustainable first-year withdrawal | 4% of the nest egg, adjusted for inflation after |
| Savings rate | Share of gross income put aside | Often cited as 15%, including employer match |
| Employer match | Free contribution from your employer | Contribute at least enough to capture it fully |
The 4 percent rule comes from historical study of a specific portfolio over 30-year periods. Early retirement, poor returns in the first years, or high fees can all make a lower withdrawal rate necessary. Treat it as a planning anchor rather than a promise.
The single most consequential variable in retirement planning is when you start, because compound growth rewards time more than amount. Ten years of early contributions frequently outweigh twenty years of later ones at the same monthly figure.
This is not an argument for perfectionism. It is an argument for starting with whatever amount is currently possible rather than waiting for a moment when a larger contribution feels comfortable. Contributions can always be increased later; the years cannot be recovered.
