Compound interest can significantly enhance savings in high-interest accounts, providing accelerated growth over time.
Understanding Compound Interest
Compound interest refers to the process of earning interest on previously earned interest. In high-interest savings accounts, this effect can lead to substantial growth in your savings over time. The interest is calculated on the initial principal, which also includes all the accumulated interest from previous periods.
How Compound Interest Works
- Principal Amount: The initial sum of money deposited or invested.
- Interest Rate: The percentage at which the money earns interest, usually expressed as an annual percentage.
- Time Period: The duration the money is left to grow, often measured in years.
- Compounding Frequency: How often the interest is calculated and added to the account (e.g., annually, semi-annually, quarterly, monthly, daily).
Formula for Compound Interest
The formula to calculate compound interest is as follows:
A = P (1 + r/n)^{nt}
Where:
- A: The future value of the investment/loan, including interest.
- P: The principal investment amount (initial deposit).
- r: The annual interest rate (decimal).
- n: The number of times that interest is compounded per year.
- t: The number of years the money is invested or borrowed for.
Example Calculation
Let’s assume the following:
- Principal (P): $1,000
- Annual Interest Rate (r): 5% or 0.05
- Compounding Frequency (n): Annually (1 time per year)
- Time (t): 10 years
Using the formula to calculate the future value:
A = 1000 (1 + 0.05/1)^{1*10} = 1000 (1.05)^{10} ≈ 1628.89
After 10 years, the account will grow to approximately $1,628.89.
Compound Interest Table
| Years | Amount with 5% Interest | Amount with 10% Interest |
|---|---|---|
| 1 | $1,050.00 | $1,100.00 |
| 5 | $1,276.28 | $1,610.51 |
| 10 | $1,628.89 | $2,593.74 |
| 20 | $2,653.30 | $6,727.50 |
