According to some embodiments, account information may be received in connection with a potential insurance policy. A premium indication portal processor may receive, from a risk score model application, an account score matrix for the potential insurance policy, including grade values comparing the account information with other insured policies in a risk database, along with a benchmark premium value calibrated to a target return on equity based on the account information and information in the risk database. The account score matrix may be displayed on an underwriter device, and guide indication adjustments may be received from the underwriter device for the potential insurance policy. The premium indication portal processor may then automatically calculate an adjusted premium value calibrated to the target return on equity based at least in part on the guide indication adjustments.
