Key Formulas Used in Actuarial Calculator
This tool is based on financial mathematics and actuarial science principles.
1. Working Years Formula
Working Years = Retirement Age − Current Age
Example:
Retirement Age = 60
Current Age = 30
Working Years = 30
2. Future Income Value Formula
This calculates the expected income at retirement using compound growth.
Formula:
Future Income = Current Income × (1 + Growth Rate / 100) ^ Years
Example:
- Income = $50,000
- Growth Rate = 5%
- Years = 30
Future Income = 50,000 × (1.05)^30
= $216,097 (approx.)
3. Present Value Formula
This calculates today's value of future income.
Formula:
Present Value = Future Income ÷ (1 + Interest Rate / 100) ^ Years
Example:
- Future Income = $216,097
- Interest Rate = 6%
- Years = 30
Present Value ≈ $37,748
4. Lifetime Earnings Formula
This calculates total earnings over the working period with growth applied yearly.
Formula:
Lifetime Earnings = Σ [Income × (1 + Growth Rate)^i]
Where i = each working year.
Example Calculation Using Actuarial Calculator
Let’s understand with a real-world scenario.
Input Values:
| Parameter | Value |
|---|---|
| Current Age | 28 years |
| Retirement Age | 60 years |
| Annual Income | $40,000 |
| Growth Rate | 4% |
| Interest Rate | 6% |
Step 1: Working Years
60 − 28 = 32 years
Step 2: Future Income
40,000 × (1.04)^32
= $138,000 approx.
Step 3: Present Value
138,000 ÷ (1.06)^32
= $25,400 approx.
Step 4: Lifetime Earnings
Sum of increasing income over 32 years
= $1,850,000 approx.
Results Summary Table
| Metric | Value |
|---|---|
| Working Years | 32 years |
| Future Income | $138,000 |
| Present Value | $25,400 |
| Lifetime Earnings | $1,850,000 |
