Complete Guide to Retirement Planning
Retirement planning is the process of determining retirement income goals and the actions needed to achieve those goals. It involves identifying income sources, estimating expenses, implementing a savings program, and managing assets and risk. The earlier you start planning, the more time your investments have to grow through the power of compound interest.
Our retirement calculator helps you estimate how much you need to save for a comfortable retirement, taking into account factors like current age, retirement age, current savings, monthly contributions, expected investment returns, and inflation.
Key Retirement Calculations
Future Value of Savings
FV = PV × (1 + r)ⁿ + PMT × [((1 + r)ⁿ - 1) / r]
Where:
- FV = Future value (retirement corpus)
- PV = Present value (current savings)
- r = Expected rate of return (per period)
- n = Number of periods until retirement
- PMT = Regular contribution amount
The 4% Rule for Withdrawals
The 4% rule suggests you can safely withdraw 4% of your retirement portfolio in the first year, then adjust for inflation each subsequent year. This approach is designed to make your savings last 30+ years.
Annual Withdrawal = Retirement Corpus × 0.04
