Good to know

• Starting value and years must be positive; ending value can be zero. No intermediate deposits, withdrawals, or cash-flow timing are supported.
• Decimal inputs have at most 120 characters and magnitude from 1e-100 to 1e15, or zero. Floating-point results are rounded to 12 significant digits; extreme derived results may underflow or be rejected. Exact integer results are identified separately.
• Educational estimate with user-entered assumptions, not a quote or financial/tax advice. Rates are hypothetical, fixed, and not fetched. Fees, taxes, inflation, payment-day conventions, and currency rules are excluded unless explicitly entered.
