Formula Behind Add Money Calculator
This calculator uses compound interest and annuity growth formulas.
1. Future Value of Initial Investment
Formula:
FV = P × (1 + r/n)^(n×t)
Where:
- P = Initial amount
- r = Annual interest rate
- n = Compounding periods per year
- t = Time in years
2. Future Value of Monthly Contributions
Formula:
FV = PMT × [( (1 + r)^n − 1 ) / r ] × (1 + r)
Where:
- PMT = Monthly contribution
- r = Monthly interest rate
- n = Total number of months
3. Total Value
Total Value = Future Value of Principal + Future Value of Contributions
4. Interest Earned
Interest = Total Value − Total Invested
Example Calculation
Let’s understand with a real-life example.
Scenario:
- Initial Investment: $5,000
- Monthly Contribution: $200
- Annual Interest Rate: 7%
- Time Period: 10 years
- Compounding: Monthly
Step 1: Total Invested
- $5,000 initial
- $200 × 120 months = $24,000
Total Invested = $29,000
Step 2: Future Value
After compounding growth:
Future Value ≈ $43,200 (approx.)
Step 3: Interest Earned
$43,200 − $29,000 = $14,200
Final Result:
| Category | Amount |
|---|---|
| Total Invested | $29,000 |
| Future Value | $43,200 |
| Interest Earned | $14,200 |
Investment Growth Table (Example)
| Years | Invested Amount | Estimated Value (7%) |
|---|---|---|
| 1 | $7,400 | $7,700 |
| 3 | $11,000 | $12,800 |
| 5 | $17,000 | $20,300 |
| 10 | $29,000 | $43,200 |
| 20 | $53,000 | $98,000 |
