Key Concepts in Retirement Planning
Power of Compound Interest
Starting early allows your investment returns to generate their own earnings, exponentially accelerating your fund growth over time.
Impact of Inflation
Inflation reduces purchasing power over time. Ensuring your portfolio returns outpace annual inflation is essential for long-term security.
The 4% Safe Withdrawal Rule
A widely used guideline suggesting you can withdraw 4% of your total fund annually in retirement without prematurely depleting capital.
Frequently Asked Questions
How does this calculator estimate future retirement savings?
The calculator applies standard compound interest formulas using your starting balance, monthly contributions, expected annual return rate, and total years remaining until your target retirement age.
What is a realistic expected rate of return?
Returns depend on risk profile: conservative portfolios (bonds/cash) typically average 4%–5%, while balanced or growth portfolios (diversified index funds) historically yield 6%–8% over long-term horizons.
When should I start saving for retirement?
The earlier you start, the better. Beginning in your 20s or 30s significantly lowers the monthly amount you need to save to reach your goal due to decades of compounding growth.
