In Indiana the median single-family flood policy cost $955 a year on July 31, 2026, roughly $80 a month, with the Reserve Fund Assessment, the HFIAA surcharge and the Federal Policy Fee included. That is below the national median of $1,081, and the state is close to the end of its price transition: priced at full risk, the same policies would have a median bill of $1,009, and only 34 % still pay less than their full-risk premium; only 12 of the 51 jurisdictions in the data, DC included, have a lower share. The market is small. Only 12,527 homes are insured, and 74 % of them are in A zones, where a federally regulated lender requires a policy. Bills differ little by zone, $978 in A zones and $899 in X zones, and FEMA's 2023 table counts no surge exposure in the state.
Few insured homes
The USGS gauges the Wabash, the White and the Ohio rivers in Indiana, and the state has 337 ZIP codes with flood policies in FEMA's 2023 table. Still, Marion County, which includes Indianapolis, leads with just 1,983 single-family policies. The eight largest counties together hold a minority of the state total; the rest is spread thinly over the other counties.
74 % of policies are in A zones, where the mortgage rule applies: a federally regulated lender requires flood insurance for a loan on a building in a high-risk zone. Fewer homes outside those zones are insured, though they produced 301 paid claims from 2016 to 2025.

The Ohio River counties
Clark County, where the USGS gauges the Ohio River at Clarksville and which borders Louisville's Jefferson County, Kentucky, is where losses run deepest among the large counties. It recorded 169 paid single-family claims over the decade, with a median of $36,246, 2.4 times the state median claim of $15,160. Its median bill, $1,118 on July 31, 2026, is the highest of the eight. Vanderburgh County, which includes Evansville and its Ohio River gauge, paid $925 at the median.
Lake and Kosciusko counties
Lake County, which borders Cook County, Illinois, holds 839 policies at a median of $1,004. FEMA counted 1 % of Indiana's single-family policies as exposed to Great Lakes flooding. Kosciusko County has the cheapest median of the larger counties, $749.
Recent floods and the remaining gap
The largest event in the file is Central U.S. April Flooding in 2025, with 226 paid claims for $9,777,266; losses of 2025 are still being settled. Carroll County had the widest gap in the 2023 table, $995 against $2,288, on 219 policies. The monthly cost guide explains how the fixed fees weigh on a small bill.
