Flood Insurance Cost & Coverage Calculator

Premium by flood zone and elevation, and the gap a standard homeowners policy leaves.

Read the how-to
The formula

How this number is built

premium ≈ (coverage ÷ 1,000) × base rate × zone × elevation × basement × deductible factors
Step by step

Doing it by hand

Step 1

Find your flood zone and base flood elevation from the official flood map for the address.

Step 2

Get an elevation certificate if the property sits near the base flood level; it can cut the premium sharply.

Step 3

Note the federal coverage caps and consider excess flood coverage above them.

Step 4

Buy well before you need it — policies commonly carry a waiting period before cover starts.

Questions

What people ask next

Does homeowners insurance cover flooding?

No. Surface flooding is excluded from standard policies and requires a separate flood policy.

Is coverage worth it outside a high-risk zone?

Frequently, because premiums there are much lower and a meaningful share of claims come from those zones.
