Where:
Explanation: The formula calculates how your money grows with daily compounding, which means interest is calculated on your principal plus previously earned interest every day.
Details: Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods. Daily compounding means interest is calculated and added to your balance every day, leading to faster growth than monthly or annual compounding.
Tips: Enter your initial deposit amount, the annual interest rate (default is 4.60% for SoFi), and the number of years you plan to save. The calculator will show your projected balance at the end of the period.
Q1: How often is interest compounded in high-yield savings accounts?
A: Most high-yield savings accounts, including SoFi, compound interest daily and credit it to your account monthly.
Q2: Is the interest rate guaranteed?
A: No, APY can change based on market conditions. The calculator uses the current rate for projections.
Q3: Are there any fees that would affect these calculations?
A: Most high-yield savings accounts have no monthly fees, but check with your specific bank for any account requirements.
Q4: How does this compare to regular savings accounts?
A: High-yield accounts typically offer 10-20x higher interest rates than traditional savings accounts.
Q5: Are there tax implications for the interest earned?
A: Yes, interest earned is considered taxable income and must be reported on your tax return.
