Monthly Compounding Formula:
From: | To: |
Monthly compounding means your interest is calculated and added to your principal each month, allowing you to earn interest on your interest. This leads to faster growth compared to simple interest or annual compounding.
The calculator uses the monthly compounding formula:
Where:
Example: $10,000 at 4.10% APY for 5 years = $10,000 × (1 + 0.0410/12)^(12×5) = $12,268.47
Details: High-yield savings accounts (like Synchrony, Ally, Marcus) offer significantly higher interest rates than traditional banks, with FDIC insurance up to $250,000. Monthly compounding maximizes your earnings.
Tips: Enter your initial deposit, current APY (e.g., 4.10%), and time horizon. The calculator shows your projected balance and interest earned.
Q1: How often do high-yield savings accounts compound?
A: Most compound interest daily and pay it monthly, though this calculator uses monthly compounding for conservative estimates.
Q2: Are high-yield savings accounts safe?
A: Yes, when FDIC-insured (up to $250,000 per depositor per bank).
Q3: How does this compare to CDs?
A: Savings accounts offer liquidity while CDs typically have higher rates but lock up your money.
Q4: Will rates stay this high?
A: Rates fluctuate with the federal funds rate. This calculator helps project growth at current rates.
Q5: Are there any fees?
A: Most online high-yield accounts have no monthly fees, but always check terms.
