This calculator helps you estimate the growth of your money in a high-yield checking account using compound interest. High-yield checking accounts offer better interest rates than traditional checking accounts, typically with certain balance requirements.
The calculator uses the compound interest formula:
Where:
Explanation: The formula accounts for how often interest is compounded (daily, monthly, quarterly) and how that affects your total earnings over time.
Details: Compound interest allows your money to grow exponentially because you earn interest on both your initial deposit and the accumulated interest from previous periods.
Tips: Enter your initial deposit, the account's annual interest rate (APY), how often interest compounds (typically monthly for checking accounts), and the time period you plan to keep the money in the account.
Q1: What's a typical APY for high-yield checking?
A: Rates vary but typically range from 0.25% to 2.00% APY, often with balance requirements (e.g., Ally offers 0.25% APY for balances over $15,000).
Q2: How often do checking accounts compound interest?
A: Most compound interest daily but credit it monthly.
Q3: Are there fees or requirements?
A: Some accounts require minimum balances, direct deposits, or limited withdrawals to earn the high yield.
Q4: How does this compare to savings accounts?
A: High-yield savings typically offer slightly higher rates but with more withdrawal restrictions.
Q5: Is my money safe in these accounts?
A: Yes, if the bank is FDIC-insured (up to $250,000 per depositor).
