Estimate your retirement savings goal, see if you are on track, and discover how small changes today can transform your financial future.
Retirement planning is one of the most important financial undertakings of your life, yet most people spend more time planning a vacation than planning for decades of life after work. The question "How much do I need to retire?" does not have a single answer — it depends on your lifestyle, expected expenses, Social Security benefits, and how long you will need your money to last. Our free retirement calculator takes all these factors into account and gives you a clear, personalized projection of where you stand and what adjustments you might need.
Whether you are 25 and just starting your career or 55 and wondering if you have saved enough, this guide will help you understand the key concepts, use the calculator effectively, and build a retirement strategy you can feel confident about.

Open Retirement Calculator →A retirement calculator is a comprehensive financial planning tool that estimates how much money you will have at retirement based on your current savings, monthly contributions, expected investment returns, and years until retirement. It then compares that projected balance against your estimated retirement expenses to determine whether you are on track — or how much more you need to save.
Our Risetop retirement calculator factors in inflation, Social Security income, expected retirement spending, and investment growth to give you a realistic picture. It also shows you what happens if you retire early, delay retirement, increase your contributions, or adjust your spending.
Planning your retirement takes just a few minutes with our tool:
Scenario: Two people both want $1 million by age 65 at 7% annual returns. Person A starts at 25; Person B starts at 35.
| Factor | Person A (Starts 25) | Person B (Starts 35) |
|---|---|---|
| Investment Period | 40 years | 30 years |
| Monthly Contribution Needed | $381 | $820 |
| Total Contributions | $182,880 | $295,200 |
| Final Balance | $1,000,000 | $1,000,000 |
Person A contributes $112,320 less but ends up with the same result — all because of 10 extra years of compounding. Starting early is the single most impactful decision in retirement planning. Use our calculator to see what your age means for your monthly savings target.
Scenario: You are 40 years old with $150,000 saved. You contribute $800/month, expect 7% returns, and plan to retire at 65. Your desired annual retirement income is $60,000 (including $20,000 Social Security).
| Factor | Amount |
|---|---|
| Current Savings | $150,000 |
| Monthly Contribution | $800 |
| Years to Retirement | 25 |
| Projected Balance at 65 | $936,238 |
| 4% Safe Withdrawal | $37,449/year |
| Plus Social Security | $20,000/year |
| Total Annual Income | $57,449 |
| Gap | $2,551/year |
You are close but slightly short. Increasing contributions by just $50/month ($850 total) closes the gap entirely, giving you a projected balance of $987,000 — enough for $59,480/year plus Social Security. Small adjustments compound into big results.
Scenario: $500,000 saved at age 50, contributing $1,500/month at 7% returns. Comparing retiring at 60 vs. 65 vs. 70.
| Retirement Age | Portfolio Balance | 4% Annual Income | Years Money Must Last (to 90) |
|---|---|---|---|
| 60 | $1,037,000 | $41,480 | 30 years |
| 65 | $1,622,000 | $64,880 | 25 years |
| 70 | $2,448,000 | $97,920 | 20 years |
Each additional 5 years of work nearly doubles your portfolio — and your retirement income. Retiring at 65 instead of 60 means 57% more income. If early retirement is your dream, you will need a significantly larger savings rate or a more frugal lifestyle to make it work.
A common guideline is the 25x rule: save 25 times your annual expenses. If you spend $50,000/year, aim for $1.25 million. The 4% rule suggests you can safely withdraw 4% of your portfolio in year one, adjusting for inflation annually, with a high probability of not running out over a 30-year retirement. However, individual needs vary widely based on healthcare costs, desired lifestyle, debt, and whether you own your home.
The 4% rule states that you can withdraw 4% of your retirement portfolio in the first year, then increase that amount by inflation each subsequent year, and have a 95%+ chance of your money lasting 30 years. On a $1 million portfolio, that is $40,000 in year one. It is based on historical market returns across decades including the Great Depression, stagflation, and multiple recessions. It is a starting point, not a guarantee — adjust based on your risk tolerance and spending flexibility.
Financial experts recommend saving 15–20% of your gross income for retirement, including any employer match. If you earn $60,000/year, aim for $750–$1,000/month. Starting early is critical — a 25-year-old needs to save about $381/month to reach $1 million by 65 at 7% returns, while a 40-year-old would need to save $820/month for the same goal. Automating contributions through payroll deduction makes consistency effortless.
Traditional retirement age is 65–67 (when full Social Security benefits begin), but you can retire at any age if your savings and passive income cover your expenses. The FIRE (Financial Independence, Retire Early) movement shows it is possible to retire in your 40s or even 30s with aggressive saving rates of 50–70% of income. Use our retirement calculator to model different retirement ages and see what each one requires.
Yes, but treat it as a supplement, not a foundation. The average Social Security benefit in 2025 is approximately $1,900/month, which covers basic expenses but not a comfortable lifestyle for most people. You can check your estimated benefits at ssa.gov based on your earnings history. Benefits increase by about 8% for each year you delay claiming past full retirement age (up to age 70), which can be a powerful strategy if you can afford to wait.
