A mortgage calculator for South Dakota estimates the full monthly cost of a South Dakota home loan: principal and interest from standard amortization, plus property tax, homeowners insurance and private mortgage insurance (PMI) when you put down less than 20%. It also shows the $0.50 per $500 state transfer fee due at closing.
How the Mortgage Calculator South Dakota Formula Works (Worked Example)
Principal and interest use the standard amortization formula M = P × r(1+r)n ÷ ((1+r)n − 1), where P is the loan amount, r the monthly rate (annual rate ÷ 12) and n the number of payments. Property tax is the home price × your local rate ÷ 12, insurance is your annual premium ÷ 12, and PMI is the loan amount × your PMI rate ÷ 12. Example: a $300,000 South Dakota home, 10% down, 30-year fixed at a user-entered 6.5% (click Load Example above to reproduce it).
| Item | Inputs | Monthly |
|---|---|---|
| Principal & interest | $270,000 loan, 6.5%, 360 payments | $1,706.58 |
| Property tax | 1.00% of $300,000 ($3,000/yr) | $250.00 |
| Homeowners insurance | $1,600/yr (example — use your quote) | $133.33 |
| PMI | 0.6% of $270,000 ($1,620/yr) | $135.00 |
| Total monthly payment | $2,224.92 | |
| State transfer fee, seller (grantor) (one-time) | on $300,000 | $300.00 |
Over 30 years this loan pays about $344,370 in interest. Your rate is an input, not an assumption — check the current weekly national average in Freddie Mac’s Primary Mortgage Market Survey and compare lender Loan Estimates.
South Dakota Property Tax Rate and Your Monthly Payment
The Tax Foundation puts South Dakota’s effective property tax rate at about 1.00% of owner-occupied home value (annual property tax paid ÷ home value, from Census American Community Survey data), so the calculator defaults to 1.00%. Owner-occupied homes are taxed at a lower school levy than other property, which is part of why the effective rate is close to 1%; your county auditor or treasurer can confirm the levy for your address.
| Effective rate | Annual tax on $300,000 | Added to monthly payment |
|---|---|---|
| 0.75% | $2,250 | $187.50 |
| 1.00% (Tax Foundation statewide average) | $3,000 | $250.00 |
| 1.40% | $4,200 | $350.00 |
South Dakota Closing Costs: Transfer Fee and Other Fees
South Dakota charges one statewide real estate transfer fee rather than county transfer taxes. Under SDCL § 43-4-21 the fee is 50 cents for each $500 of value or fraction of $500 — effectively $1 per $1,000 — and it is paid by the grantor, so the seller normally pays it. SDCL § 43-4-22 lists exempt transfers.
| South Dakota item | Amount | Usually paid by |
|---|---|---|
| Real estate transfer fee (SDCL § 43-4-21) | $0.50 per $500 of value — $300 on $300,000 | Seller (grantor) |
| County recording fees | Set by the county — see your Loan Estimate | Party recording the document |
| Escrow deposits for tax and insurance | Set by your lender — see your Loan Estimate | Buyer |
| Lender, appraisal and title charges | Vary by lender and title company — compare Loan Estimates | Negotiable |
Some costs are negotiable, and sellers sometimes cover part of a buyer’s closing costs as a concession.
How South Dakota Mortgage Rates Affect Your Payment
Rates in South Dakota follow national mortgage markets and vary by lender, credit score, down payment and loan type. On a $305,000 home with 20% down, an example rate of 6.95% produces a monthly principal and interest payment of about $1,615. A 0.25-point higher rate adds roughly $41 a month, so shopping several lenders can save thousands over the life of the loan.
Adjustable-rate mortgages (ARMs) often start lower but carry rate-reset risk, while a fixed rate keeps principal and interest the same for the whole term. FHA loans (3.5% down) and VA loans (0% down for eligible veterans) are alternatives to a conventional loan in South Dakota.
First-Time Buyer Programs in South Dakota
South Dakota Housing (the South Dakota Housing Development Authority) runs first-time buyer mortgage and down payment assistance programs; check its website for current income limits and terms.
FHA loans are available nationwide and require 3.5% down with a 580+ credit score. USDA loans offer 0% down for eligible rural properties in South Dakota. VA loans are available to qualified veterans and active-duty service members with no down payment required and no PMI.
If your down payment is below 20%, Private Mortgage Insurance (PMI) on a $270,000 loan adds about $135/month at a 0.6% annual rate. Experian, citing the Urban Institute puts typical PMI at roughly 0.46%–1.5% of the loan per year depending on credit score, so enter your lender’s quote in the PMI field. PMI can be removed once your loan-to-value ratio reaches 80%, and extra payments get you there sooner.

Frequently Asked Questions
What is the average mortgage rate in South Dakota in 2026?
South Dakota mortgage rates track national averages and change weekly. Check the Freddie Mac Primary Mortgage Market Survey for the current 30-year fixed average, then compare quotes from several lenders - your rate depends on credit score, down payment and loan type. The 6.95% default in this calculator is only an example.
What is the average monthly mortgage payment in South Dakota?
There is no single average - it depends on price, rate and local tax. As an example, a $305,000 home with 20% down at 6.95% has principal and interest of about $1,615 a month; adding 1.00% property tax and $1,600 a year for insurance gives an estimated PITI of about $2,003 a month.
