Homeowners insurance in South Dakota costs $3,965 a year on average in 2026 for a $400,000 dwelling policy, according to NerdWallet, or about $330 a month. Other datasets put the same state average anywhere from $2,616 to $3,965 a year, because they price different houses with different methods. This post lays out what each dataset actually measures, what South Dakota homeowners pay by city and carrier, and what moves your own premium.
The spread between sources is worth understanding before you shop. NerdWallet prices a $400,000 dwelling for a 40 year old homeowner with good credit. ValuePenguin prices a $350,000 dwelling for a 45 year old married man with no claims. Insurify uses real quotes for a $300,000 dwelling. A bigger house costs more to insure, so the $400,000 figures run higher by design. None of these numbers is wrong. They answer slightly different questions.
How much is homeowners insurance in South Dakota in 2026?
For a $400,000 dwelling with a $1,000 deductible, South Dakota homeowners pay about $3,965 a year, or $330 a month, according to NerdWallet. That is about 59 percent above the national average of $2,490 a year for the same coverage. Smaller houses cost less. For a $300,000 dwelling, the average runs $2,616 to $3,760 a year depending on the dataset.
| Source | Dwelling coverage | Average per year | Average per month | National average in the same study |
|---|---|---|---|---|
| NerdWallet (May 2026) | $400,000 | $3,965 | $330 | $2,490 |
| ValuePenguin (Sept 2026) | $350,000 | $3,258 | $272 | $2,395 |

One more figure puts the study averages in context. The U.S. Census Bureau American Community Survey reports that South Dakota homeowners with a mortgage said they paid a median of $1,354 a year in the 2023 five year estimates. That figure counts every policy in force, including older homes with low dwelling limits and longtime customers with loyalty discounts. The study figures above price one sample home at current filed rates. Use the study figures to compare companies and the Census figure as a reminder that your own quote depends on your house.
ValuePenguin also publishes a national table that lists South Dakota at $2,596 a year, which conflicts with its own South Dakota page figure of $3,258. The two pages use different samples and update on different schedules. The state page figure is the one built from South Dakota ZIP codes, so this post uses $3,258 as the ValuePenguin number and notes the conflict rather than hiding it.
Why South Dakota home insurance rates jumped 57 percent in five years
Home insurance prices in South Dakota rose 57.2 percent between 2021 and 2025, the tenth highest increase in the country, according to ValuePenguin and S and P Global RateWatch data drawn from National Association of Insurance Commissioners filings. The biggest single jump came in 2024, when prices surged 18.48 percent. Rates rose another 6.46 percent in 2025.
| Year | Average rate increase |
|---|---|
| 2021 | 4.74 percent |
| 2022 | 6.37 percent |
| 2023 | 11.75 percent |
| 2024 | 18.48 percent |
| 2025 | 6.46 percent |
The increases did not hit every carrier the same way. Chubb raised prices close to 130 percent over the five years. USAA raised rates 26.4 percent and State Farm 29.8 percent, the smallest jumps among the large carriers ValuePenguin tracked. A carrier that held its rates down for five years can still be the expensive one today if it started high, so the trend matters less than the current quote for your house.
What South Dakota homeowners pay by city
Where you live in South Dakota moves the premium by more than $1,400 a year. The eastern side of the state tends to cost less than the western and southern parts. Aberdeen, in the northeast, has the cheapest average rates in the state at $2,732 a year. Buffalo Gap, in the southwest near Wind Cave National Park, has the highest at $4,196 a year.
| City | Average per year | Cheapest company | Cheapest rate per year |
|---|---|---|---|
| Aberdeen | $2,732 | State Farm | $1,888 |
| Brookings | $2,811 | American Family | $2,014 |
| Sioux Falls | $3,111 | American Family | $2,242 |
| Belle Fourche | $3,760 | State Farm | $1,627 |
| Rapid City | $3,972 | State Farm | Not published |
| Buffalo Gap | $4,196 | State Farm | $2,063 |
Sioux Falls, the largest city, averages $3,111 a year, about 5 percent below the state average. American Family is the cheapest carrier there at $2,242 a year, which is 28 percent below the city average. Rapid City runs $3,972 a year, $714 above the state average. The Rapid City gap shows up in the cheapest carrier column too: State Farm prices far below the city average in Belle Fourche at $1,627 a year, while the city average sits at $3,760. The same company can be the cheapest in one town and mid priced in the next, which is why a statewide cheapest list is only a starting point.
Who has the cheapest homeowners insurance in South Dakota?
State Farm has the cheapest home insurance in South Dakota for most people, with an average rate of $2,133 a year for $350,000 in dwelling coverage, according to ValuePenguin. That is $1,125 a year below the state average of $3,258 for the same coverage. State Farm also holds cheap rates across home values from $200,000 to $1 million in dwelling coverage, and it raised rates less than most competitors over the last five years.
| Company | Average per year, $200,000 dwelling | Complaints, NAIC |
|---|---|---|
| State Farm | $1,568 | Average |
| Farmers Mutual of Nebraska | $1,589 | Low |
| North Star Mutual | $1,704 | Average |
| Auto-Owners | $1,950 | Low |
| American Family | $2,077 | Average |
| USAA, military only | $2,531 | Low |
| Nationwide | $2,801 | High |
| Farm Bureau | $3,133 | Low |
Those rates are for a $200,000 dwelling, the level where ValuePenguin publishes a full company table. The spread is wide: Farm Bureau costs about twice what State Farm charges for the same house. Auto-Owners is the best rated home insurance company in South Dakota, with about 61 percent fewer complaints than expected according to NAIC data, and strong claims service scores from J.D. Power. Price and service point in different directions here: State Farm wins on price, Auto-Owners wins on complaints, and American Family wins in Sioux Falls specifically.
USAA averages $2,531 a year in South Dakota, but only military members, veterans, and some family members can buy it. For a $1 million dwelling, the ranking changes again, so homeowners with high value houses should get quotes from Chubb and other high value specialists rather than assuming the mass market cheapest carrier stays cheapest.
What drives the cost: hail, wind, and the deductible that follows
Wind and hail are the most common causes of home damage in South Dakota. Standard home insurance covers both, but the deductible is where the cost lands on the homeowner. Many South Dakota policies carry a separate wind and hail deductible, usually 1 or 2 percent of the dwelling limit, instead of the flat $1,000 deductible on the rest of the policy. On a $350,000 home, a 1 percent wind and hail deductible means $3,500 out of pocket before the insurer pays on a hail claim.
The storm numbers explain why carriers price this way. South Dakota reported 613 windstorms in 2025, according to the NOAA National Weather Service Storm Prediction Center, and only eight states had more. Hail damage is so common that a single storm can damage thousands of roofs in one afternoon, and roof age matters more in South Dakota than in most states. A roof near the end of its life may be settled at actual cash value, the depreciated value, rather than full replacement cost.
Flood is the coverage gap most South Dakota homeowners miss. Home insurance almost never covers flood damage. The National Flood Insurance Program has handled more than 1,870 flood insurance claims in South Dakota since 2000, causing more than $50 million in damage, according to FEMA. Flooding is more common in the eastern part of the state. A separate flood policy from the NFIP or a private carrier is the only way to cover it.
A worked example: the same house, three quotes
Take a $350,000 dwelling in Sioux Falls with a $1,000 deductible. The city average is $3,111 a year. American Family averages $2,242 a year there, $869 below the city average. State Farm averages $2,133 a year statewide, $1,125 below the state average. A homeowner who takes the first renewal quote instead of comparing three carriers can easily pay $800 to $1,100 a year more for the same coverage on the same house. The gap is the whole story in South Dakota: the state average is high, but the cheapest carriers price far below it.
How to lower your South Dakota homeowners insurance premium
Start by deciding how much coverage you actually need. Most basic policies cover the structure, your belongings, liability, and extra living costs, but the dwelling limit should match rebuild cost, not market value. A home that would cost $300,000 to rebuild does not need $400,000 of dwelling coverage, and the extra limit adds premium for nothing.
Get quotes from at least three companies, and include one regional carrier. Farmers Mutual of Nebraska and North Star Mutual both price below the big national carriers in South Dakota, and neither shows up in most national cheapest lists because they only write in a handful of states. Ask each carrier about the same discounts: bundling home and auto, a new roof, a monitored alarm, and a higher deductible. Raising the deductible from $1,000 to $2,500 cuts the premium, but only take the higher deductible if you can pay it after a storm without borrowing.
Your credit score shapes the price more than most homeowners expect. Our guide to how a credit score affects homeowners insurance premiums explains which states limit the practice and how much a lower score can add. Roof age matters too: our guide to how roof age affects homeowners insurance rates covers when a carrier switches a roof to actual cash value settlement. For comparison with other storm heavy states, see our Kansas homeowners insurance guide, our Nebraska homeowners insurance guide, and our Colorado homeowners insurance guide.
What to remember about South Dakota homeowners insurance
South Dakota homeowners pay $3,965 a year on average for a $400,000 dwelling, or $3,258 for a $350,000 dwelling, depending on which house the dataset prices. Rates rose 57 percent in five years, driven by hail and wind claims. State Farm is cheapest for most people at $2,133 a year, and the city you live in moves the price by more than $1,400 a year. Check whether your policy carries a separate wind and hail deductible, and remember flood needs its own policy.
