Example Calculation
Let’s understand how the annuity calculator works with a real-life example:
- Periodic Payment: $300
- Interest Rate: 5% per year
- Number of Periods: 10 years
- Annuity Type: Ordinary
Step 1: Total Contribution
$300 × 10 = $3,000
Step 2: Future Value
Using the annuity formula, the investment grows with compound interest over time.
Approximate result:
Future Value ≈ $3,773
Step 3: Interest Earned
$3,773 − $3,000 = $773
This shows how consistent investing can significantly increase your wealth over time.
Ordinary Annuity vs Annuity Due
Understanding the difference between these two types is crucial:
Ordinary Annuity
- Payments made at the end of each period
- Slightly lower future value
- Common in loans and savings plans
Annuity Due
- Payments made at the beginning of each period
- Higher future value due to extra interest time
- Common in rent or insurance payments
