How to use ROI Calculator

ROI is (total proceeds − investment cost) ÷ investment cost × 100. Include all relevant proceeds and costs in the amounts you enter.

Cost must be positive and proceeds nonnegative. This is a total-period arithmetic return; it ignores timing and intermediate cash flows.
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.

Reconcile current holding values with user-chosen target weights and a cash contribution or withdrawal.

Decompose a user-supplied return on equity into profit margin, asset turnover and equity multiplier.
