How Savings is Calculated
Interest compounds on both starting balance and ongoing monthly deposits using the monthly periodic rate (Annual Rate / 12).
P is initial deposit, PMT is monthly deposit, r is monthly interest rate, and n is total months.
- 1Total Principal Deposited = $5,000 + ($400 × 120) = $53,000
- 2Future Value with Monthly Compounding = $69,458.12
- 3Total Interest Earned = $16,458.12
What affects Savings results
- Interest rate fluctuations on variable high-yield savings accounts.
- Consistency of monthly deposit timing.
