Earning interest in a savings account helps your money grow over time. Let’s break down how to calculate it and maximize your earnings!

1. Simple Interest Formula

Simple interest provides a quick estimate of your earnings:

Formula:
Interest = P × R × T
- P = Principal amount (starting balance).
- R = Annual interest rate (as a decimal).
- T = Time period (in years).

Example:
- Deposit: $10,000
- Rate: 4% (0.04 as a decimal)
- Time: 1 year
- Calculation: $10,000 × 0.04 × 1 = $400

Note: This formula gives a rough estimate but doesn’t account for compounding interest.

2. Compound Interest Formula

Compound interest includes earnings on previously earned interest, leading to faster growth.

Formula:
A = P (1 + r/n) ^ (n × t)
- A = Final amount
- P = Principal amount
- r = Annual interest rate (as a decimal)
- n = Number of compounding periods per year
- t = Time (in years)

Example with Daily Compounding:
- Deposit: $10,000
- Rate: 4% (0.04)
- Compounded: Daily (n = 365)
- Time: 5 years
- Calculation: $10,000 × (1 + 0.04/365) ^ (365 × 5) $12,214

You earn $2,214 in interest over 5 years with daily compounding compared to $2,000 with simple interest.

3. Monthly Compound Interest

For monthly compounding, adjust the formula:
- n = 12 for monthly periods.

Tip: The more frequent the compounding, the more interest earned!

4. Boosting Your Earnings

To maximize savings account interest:
- Find High-Yield Accounts: Online banks often offer higher interest rates.
- Make Regular Deposits: Consistent contributions increase your principal and compound interest.
- Leverage Tools: Use a savings calculator to estimate growth with different scenarios.

Example with Regular Deposits:
- Start: $10,000
- Add: $100/month
- Rate: 4% APY (daily compounding)
- After 5 years: ~$18,845 (includes ~$2,845 interest).

5. Other Considerations

• Interest Rate Variability: Savings account rates can change. Monitor rates to ensure you’re getting the best return.
• Certificates of Deposit (CDs): For fixed rates, consider CDs, but note early withdrawal penalties.

Final Takeaway

Start saving regularly—even small deposits add up! By understanding and leveraging compounding, you can grow your money faster and reach financial goals with minimal effort.
