Retirement Calculator
Take control of your financial future! Our Retirement Calculator helps you project your potential retirement savings (your "nest egg") and estimate the annual income you might draw from it. By inputting details about your current situation and future expectations, you can get a clearer picture of what your retirement could look like and make informed decisions today.

Understanding the Calculations & Assumptions
This Retirement Calculator uses common financial formulas to project your potential savings. Here's a brief overview:
- Future Value of Current Savings: This is calculated using the standard compound interest formula: `FV = PV * (1 + r)^n`, where PV is your current savings, r is the annual return rate, and n is the number of years until retirement.
- Future Value of Future Contributions: This is more complex as it involves a growing annuity (your contributions increase as your salary increases). The calculator iterates year by year, calculating the contribution for that year (salary × savings rate), adding it to the accumulated sum, and then applying the investment return to the new total for that year. This process repeats for each year until retirement.
- Total Nest Egg: This is the sum of the future value of your current savings and the future value of all your future contributions.
- Estimated Annual Retirement Income (4% Rule): This is a widely discussed guideline in retirement planning. It suggests that if you withdraw 4% of your retirement savings in the first year of retirement, and then adjust that amount for inflation each subsequent year, there's a high probability your money will last for at least 30 years. Our calculator simply applies 4% to your estimated total nest egg to give a rough idea of potential first-year income. This rule has its proponents and critics, and its suitability depends on many factors (market conditions, lifespan, desired withdrawal flexibility).
Key Assumptions Made by This Calculator:
- Rates of salary increase and investment return are constant over the entire period.
- Savings are made consistently each year.
- Investment returns are compounded annually.
- The calculation does not account for taxes on investment gains or retirement income.
- Inflation's impact on purchasing power is not explicitly shown in the income figure (though the 4% rule itself historically aimed to account for inflation-adjusted withdrawals).
Frequently Asked Questions (FAQ)
What is a realistic 'Expected Annual Investment Return' to use?
This is highly subjective and depends on your investment strategy, risk tolerance, and market conditions. Historically, diversified stock market investments have averaged around 7-10% annually over the long term, but this is not guaranteed and can fluctuate significantly. Bonds typically offer lower returns with lower risk. It's often advisable to use a conservative estimate (e.g., 5-7%) for long-term planning. Consulting a financial advisor is best for personalized advice.
Does this calculator consider inflation?
The calculator does not explicitly adjust the final nest egg or the estimated annual income for future inflation. The 4% withdrawal rule, historically, was developed with the idea that withdrawals could be adjusted for inflation. However, the income figure shown is in today's dollar terms relative to the future nest egg. High inflation can significantly erode the purchasing power of your savings and income.
What if my salary increase or savings rate changes over time?
This calculator assumes constant percentage rates for salary increase and savings. If you anticipate significant changes, you might need to run multiple scenarios or use more advanced financial planning software. You can, however, re-run the calculation with different average rates to see various outcomes.
Is the 4% rule always reliable for retirement income?
The 4% rule is a guideline, not a guarantee. Its success depends on factors like investment performance during retirement, inflation rates, and how long your retirement lasts. Some financial planners now suggest a more conservative withdrawal rate (e.g., 3% or 3.5%) due to changing market expectations and increased longevity. It's a good starting point for discussion but should be reviewed with a financial professional.
