Computing platforms, methods, and storage media for validating a price calculation, such as a premium calculation, are disclosed. Exemplary implementations may: obtain, from a rating system configured for calculating premiums, a rating system premium calculation based on a plurality of profiles and on a stored set of rate factors; independently calculate a local system premium calculation based on the plurality of profiles and based on a current set of rate factors associated with calculating premiums; and automatically validate the rating system premium calculation based on comparing the rating system premium calculation with the local system premium calculation.
