Understanding the Calculation Formula
The calculator uses compound interest principles to estimate future value.
1. Investment Duration
Years until retirement:
Years = Retirement Age − Current Age
2. Future Value of Current Savings
Your existing savings grow using compound interest:
Future Value = Current Savings × (1 + r)^t
Where:
- r = annual return rate
- t = number of years
3. Total Contributions
Monthly savings over time:
Total Contributions = Monthly Savings × 12 × Years
4. Growth on Contributions
Since contributions are added over time, they also grow:
Adjusted Contributions = Contributions × (1 + r)^(Years / 2)
5. Total Retirement Savings
Final retirement amount:
Total Savings = Future Value + Adjusted Contributions
6. Interest Earned
Total profit generated:
Interest = Total Savings − (Current Savings + Contributions)
Example Calculation
Let’s understand how the calculator works with a real-life example.
User Inputs:
- Current Age: 30
- Retirement Age: 60
- Monthly Savings: $500
- Annual Return Rate: 7%
- Current Savings: $10,000
Step 1: Investment Duration
Years = 60 − 30 = 30 years
Step 2: Future Value of Current Savings
$10,000 grows at 7% for 30 years:
≈ $76,123
Step 3: Total Contributions
$500 × 12 × 30 = $180,000
Step 4: Growth on Contributions
Adjusted value ≈ $344,000 (approx.)
Step 5: Final Retirement Savings
Total ≈ $76,123 + $344,000 = $420,123
Step 6: Interest Earned
Interest ≈ $420,123 − $190,000 = $230,123
