1. What is the High Yield Savings Formula?

The high yield savings formula calculates how your money grows with daily compounding interest, typical of high-yield savings accounts offered by online banks. It accounts for principal, annual interest rate (APY), and time.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

Where:

• \( A \) — Final amount ($)
• \( P \) — Principal investment ($)
• \( r \) — Annual interest rate (decimal)
• \( t \) — Time in years
• 365 — Daily compounding factor

Explanation: The formula calculates daily compounding by dividing the annual rate by 365 days and applying it over the total number of days (365 × years).

3. Importance of Compound Interest

Details: Compound interest allows your savings to grow exponentially over time, as you earn interest on both your principal and accumulated interest. High-yield accounts typically offer rates 10-20x higher than traditional savings accounts.

4. Using the Calculator

Tips: Enter principal amount in dollars, annual interest rate as a percentage (e.g., 4.5 for 4.5% APY), and time in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between APR and APY?
A: APR doesn't account for compounding, while APY does. High-yield accounts use APY to show the actual yield you'll earn.

Q2: How often is interest compounded?
A: Most high-yield accounts compound interest daily and credit it monthly.

Q3: Are high-yield savings accounts safe?
A: Yes, when from FDIC-insured banks (up to $250,000 per depositor).

Q4: What's a good high-yield savings rate?
A: As of 2023, top accounts offer 4-5% APY, significantly higher than the national average of 0.42%.

Q5: How does this compare to regular savings?
A: A $10,000 deposit at 4.5% APY earns $460 in 1 year vs. $42 at 0.42% APY.
