Compounding with a fixed 3% daily return means that each day, you earn 3% on your current balance (including previous earnings). This creates exponential growth over time.
Example: Starting with $100, on Day 1 you earn $3 (3% of $100), making your balance $103. On Day 2, you earn 3% of $103 ($3.09), making your balance $106.09, and so on.
Mathematical Formula: Final Balance = Initial Investment × (1 + Daily Rate)^Number of Days
For 3% daily over 100 days: $100 × (1.03)^100 = $100 × 19.2186 = $1,921.86
Note: This calculator assumes earnings are reinvested daily with no withdrawals or fees.
