Formula Used in Retirement Calculation
This calculator uses standard financial growth formulas based on compound interest and systematic investment planning.
1. Future Value of Current Savings
Your current savings grow using compound interest:
Future Value = Savings × (1 + r)^t
Where:
- r = annual return rate (decimal form)
- t = number of years until retirement
This formula calculates how your existing savings grow over time.
2. Future Value of Monthly Contributions
Monthly investments grow using compound interest:
FV = P × [((1 + r)^n − 1) / r]
Where:
- P = monthly contribution
- r = monthly return rate
- n = total number of months
This shows how your consistent savings build wealth over time.
3. Total Retirement Corpus
Total Corpus = Future Value of Savings + Future Value of Contributions
This gives the total amount you will have at retirement.
4. Estimated Monthly Retirement Income
The calculator assumes a safe withdrawal rate of 4% per year:
Monthly Income = Total Corpus × 0.04 ÷ 12
This provides an estimate of how much you can safely withdraw each month during retirement.
Example Calculation
Let’s understand this with a simple example:
- Current Savings: $50,000
- Current Age: 30
- Retirement Age: 60
- Annual Return Rate: 8%
- Monthly Contribution: $500
Step 1: Calculate Investment Period
60 - 30 = 30 years
Step 2: Growth of Current Savings
$50,000 grows at 8% for 30 years → approximately $503,000
Step 3: Growth of Monthly Contributions
$500 monthly investment over 30 years → approximately $745,000
Step 4: Total Retirement Corpus
$503,000 + $745,000 = $1,248,000
Step 5: Monthly Retirement Income
$1,248,000 × 4% ÷ 12 ≈ $4,160 per month
This example shows how consistent savings and compound growth can create significant wealth over time.
