How Much Do You Need to Retire?
The most widely used rule of thumb is the 25x Rule: multiply your expected annual retirement expenses by 25. If you plan to spend $50,000/year in retirement, you need a $1.25 million nest egg. This is derived from the 4% safe withdrawal rate — the rate at which research shows a portfolio historically lasts 30+ years.
How to Build Your Retirement Savings
- Maximize your 401(k) — Contribute at least enough to get your full employer match. That's an immediate 50–100% return on those dollars.
- Open a Roth IRA — Contributions grow tax-free. In 2025, the limit is $7,000/year ($8,000 if you're 50+).
- Increase contributions by 1% per year — Automating small annual increases is painless and compounds dramatically over time.
- Invest in low-cost index funds — Broad market index funds (like S&P 500 ETFs) have historically returned 7–10% annually over the long term.
- Delay Social Security — Every year you delay claiming past 62 increases your benefit by up to 8% per year until age 70.
Common Retirement Mistakes to Avoid
The biggest retirement mistake is starting too late. Due to compound interest, someone who saves $200/month from age 25 to 35 (10 years) and then stops will have more at 65 than someone who saves $200/month from age 35 to 65 (30 years). Starting a decade earlier — even for a short period — beats saving three times as long but starting late.

Frequently Asked Questions
How much should I have saved by age 40?
A common benchmark is 3x your annual salary saved by age 40. So if you earn $70,000, aim for $210,000 by 40. By 50, target 6x; by 60, target 8x. These are benchmarks, not absolutes — start wherever you are and increase contributions as much as you can.
What is the 4% rule?
The 4% rule states that retirees can withdraw 4% of their portfolio in the first year, then adjust for inflation each year, and the money should last 30 years. It's based on historical US stock and bond market data. It's a useful guideline, not a guarantee — many financial planners now use 3–3.5% for longer retirements.
What if I'm starting to save for retirement late?
It's never too late to start. If you're in your 40s or 50s, maximize your 401(k) contributions (including catch-up contributions of $7,500/year extra if you're 50+), consider delaying retirement by 2–3 years (which dramatically improves your position), and look at part-time work in early retirement to reduce withdrawals.
Should I use a Roth IRA or Traditional IRA?
If you expect to be in a higher tax bracket in retirement than now, choose Roth (pay taxes now, withdraw tax-free later). If you expect a lower tax bracket in retirement, choose Traditional (deduct now, pay taxes on withdrawals). When unsure, many advisors recommend Roth for younger savers since tax rates may rise over decades.
How does this calculator estimate my retirement?
This calculator projects your savings to retirement age using your current balance, monthly contributions, and an expected annual return. It then calculates how long your projected nest egg will last given your monthly withdrawal amount. Adjust the return rate based on your investment mix — 5–6% for conservative, 7–8% for moderate, 9–10% for aggressive equity portfolios.
