Formula Used
A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)]
Where:
- A = Final amount (future value)
- P = Initial principal balance
- r = Annual interest rate (in decimal)
- n = Number of times interest compounds per year
- t = Number of years
- PMT = Regular monthly contribution
Example Calculation
Real-World Scenario:
Sarah wants to save for a down payment on a house. She has $5,000 saved and plans to contribute $500 monthly for 5 years in a high-yield savings account earning 4.5% APY compounded monthly.
Given:
- Initial Deposit = $5,000
- Monthly Contribution = $500
- Annual Interest Rate = 4.5%
- Compound Frequency = Monthly (12 times per year)
- Savings Period = 5 years
Calculation:
A = $5,000(1 + 0.045/12)^(12×5) + $500 × [((1 + 0.045/12)^(12×5) - 1) / (0.045/12)]
Result: After 5 years, Sarah will have approximately $41,872, with $30,000 in contributions and $6,872 in interest earned.
