Methodology

Lemonade Insurance conducted an internal analysis to evaluate policy rates across different makes and models of vehicles for a 32-year-old single female customer, currently holding a Lemonade Renters Policy in the state of Illinois. The policy considered includes only liability coverages with minimum state-mandated limits, and no optional coverages or upgrades. The customer resides in a zip code with an average cost of living, and has an insurance history that reflects no accidents, violations, or claims, with average driving patterns relative to other drivers in the state. This analysis is based on Lemonade’s internal data and is meant for illustrative purposes only. Quotes may vary depending on individual circumstances.
