What limitation matters most?
Marketing ratios are only as meaningful as the inputs. Revenue attribution windows, duplicate conversions, bot traffic and what counts as a “new customer” can change the interpretation without changing the arithmetic. Use a consistent lead definition.

No. Lead Conversion Calculator applies the displayed arithmetic to the values you enter. Rules, rates, eligibility definitions and contractual terms can differ, so use the governing source for an official decision.
