Quick notes
• If you choose Annual Rate (APR), the calculator converts it to daily rate by dividing by 365 (daily_rate = APR/100 / 365).
• Formula: A = P * (1 + r_d)ⁿ where r_d = daily rate (decimal), n = number of days.
• Effective APY ≈ (1 + r_d)ⁿ – 1 recalculated to 1 year (if n is 365) — shown for reference.
