Methods and systems for providing estimated insurance quotes / premiums are described herein. After analyzing rate factors, a subset of rate factors are selected that yield a fairly accurate estimated insurance premium from a minimum amount of information easily obtainable from a user. The user inputs a value from a predetermined set of allowable inputs (value input filter). After receiving and analyzing the user inputs, the system generates one or more estimates and displays the one or more estimates to the user, e.g., via a web page. When multiple estimates are provided, the multiple estimates may differ based on the level of coverage, add-on features, or both. Readily known non-personal identifying information is preferably requested and used, thereby alleviating privacy concerns while still being able to provide an estimate to the user very quickly, e.g., under 30 seconds, once all the requested information is obtained.
