Risk Rating 2.0: Equity in Action

As of April 1, 2023, FEMA has fully implemented the National Flood Insurance Program's (NFIP) pricing methodology called Risk Rating 2.0. The methodology leverages industry best practices and cutting-edge technology to enable FEMA to deliver rates that are actuarily sound, equitable, easier to understand and better reflect a property’s flood risk.

National Flood Insurance Program policyholders can contact their insurance company or insurance agent to learn more about what Risk Rating 2.0-Equity in Action means to them. The rating methodology was implemented in phases from Oct. 1, 2021 through April 1, 2023.

FEMA continues to engage with Congress, its industry partners and state, local, tribal and territorial agencies to ensure a clear understanding of these changes that took place on the rating methodology and how it impacted policyholders.  

FEMA is committed to building a culture of preparedness across the nation. Purchasing flood insurance is the first line of defense against flood damage and a step toward a quicker recovery following a flood.

Since the 1970s, rates have been predominantly based on relatively static measurements, emphasizing a property’s elevation within a zone on a Flood Insurance Rate Map (FIRM).

The 1970s legacy rating methodology did not incorporate as many flooding variables as Risk Rating 2.0. FEMA is building on years of investment in flood hazard information by incorporating private sector data sets, catastrophe models, and evolving actuarial science. In addition, the 1970s legacy rating methodology did not account for the cost of rebuilding a home. Policyholders with lower-valued homes may have been paying more than their share of the risk while policyholders with higher-valued homes may have been paying less than their share of the risk. Risk Rating 2.0 was not just a minor improvement, but a transformational leap forward for the NFIP.

With Risk Rating 2.0 fully implemented, FEMA is using its capabilities and tools to address rating disparities by incorporating more flood risk variables. These include flood frequency, multiple flood types—river overflow, storm surge, coastal erosion and heavy rainfall—and distance to a water source along with property characteristics such as elevation and the cost to rebuild. Since the implementation of Risk Rating 2.0, FEMA is now able to equitably distribute premiums across all policyholders based on home value and a property’s flood risk, and set rates that are fairer and more equitable.

We are upholding statutory requirements by:

Limiting Annual Premium Increases
Existing statutory limits on rate increases require that most rates not increase more than 18% per year.

Using Flood Insurance Rate Maps (FIRMs) for Mandatory Purchase and Floodplain Management
FEMA’s flood map data informs the catastrophe models used in the development of rates under Risk Rating 2.0. That is why critical flood mapping data is necessary and essential for communities. It informs floodplain management building requirements and the mandatory purchase requirement.

Maintaining Features
We are maintaining features to simplify the transition to Risk Rating 2.0 by offering premium discounts to eligible policyholders. This means:

• FEMA is continuing to offer premium discounts for pre-FIRM subsidized and newly mapped properties.
• Policyholders are still able to transfer their discount to a new owner by assigning their flood insurance policy when their property changes ownership.
• And discounts to policyholders in communities who participate in the Community Rating System will continue. Communities can continue earning National Flood Insurance Program rate discounts of 5% - 45% based on the Community Rating System classification. However, since Risk Rating 2.0 does not use flood zones to determine flood risk, the discount will be uniformly applied to all policies throughout the participating community, regardless of whether the structure is inside or outside of the Special Flood Hazard Area.
