South Dakota Rent Calculator

South Dakota imposes no state individual income tax and no local wage tax, so take-home pay is federal-only, and SDCL 43-32-6.1 caps the security deposit at one month’s rent with a 14-day return. This calculator sizes the rent that income supports against both the 30 percent standard and the income ratio your landlord publishes, prices the cash you need at signing under the one-month deposit cap, and benchmarks your rent against the HUD Fair Market Rent for your county.

What Do You Want To Calculate?

The second and third modes require a target monthly rent. The third solves for annual salary.

Location and Unit

Select the county where you will rent.
Selects the HUD FY 2025 Fair Market Rent for your county.
Select a county to load its HUD Fair Market Rent schedule and the income a published screening ratio would require at that benchmark.

South Dakota rules this calculator enforces: SDCL 43-32-6.1 caps the security deposit at one month’s rent except where special conditions exist; SDCL 43-32-24 requires return of the deposit within 14 days after termination and an itemized accounting within 45 days upon the tenant’s request. SDCL 43-32-13 requires at least 30 days written notice before a month-to-month rent increase takes effect; rent cannot be raised during a fixed term. South Dakota has no statewide or local rent control, no cap on the increase size, no statewide just cause requirement and no statutory cap on application fees.

Understanding Rent Affordability in South Dakota

South Dakota has no state individual income tax and no local wage tax, so take-home pay is high relative to gross, and rents are among the nation’s lowest, so the binding constraint is usually the screening ratio and after-tax budget rather than the tax code.
  • South Dakota imposes no state individual income tax and no local wage income tax, so the only payroll deductions are federal income tax and FICA.
  • The 30 percent affordability standard requires annual income equal to 40 times the monthly rent, while the 3 times monthly ratio many SD landlords publish requires only 36 times. Test case 4 shows the solver returning the income at which the 30 percent rule binds at the Sioux Falls-area Fair Market Rent.
  • SDCL 43-32-6.1 caps the security deposit at one month’s rent except where special conditions exist; SDCL 43-32-24 requires return within 14 days after termination and an itemized accounting within 45 days upon the tenant’s request.
  • SDCL 43-32-13 requires at least 30 days written notice before a month-to-month rent increase takes effect; rent cannot be raised during a fixed term. South Dakota has no rent control and no cap on the increase size.
  • South Dakota has no statewide just cause requirement and no statutory cap on application fees.
  • South Dakota’s FY 2025 two-bedroom Fair Market Rent ranges from about $872 in the non-metropolitan interior to $1,119 in Rapid City, with Sioux Falls at $1,030 and Meade County at $1,095, against a $913 statewide average (54th lowest nationally).

Methodology Notes

  • Recommended maximum rent is the lowest of the 30 percent gross rule, the after-tax budget rule and the debt-to-income rule. The screening ratio ceiling is reported separately as an approval test.
  • The take-home engine applies federal income tax on wages minus pre-tax retirement contributions minus the federal standard deduction, less $2,000 per dependent for the first three, then FICA. South Dakota adds no state or local income tax.
  • Deposit clamping reduces any request above one month’s rent to one month under SDCL 43-32-6.1 (except special conditions).
  • Required-income mode uses a guarded bisection solver with 60 bound expansions and 90 iterations, rounded up to the next whole dollar, evaluated against the recommended affordability figure rather than a fixed multiple.
  • Fair Market Rent comparisons add tenant-paid utilities to base rent because HUD publishes FMR as a gross rent.
  • Not modeled: South Dakota state and local sales taxes, which do not apply to wage withholding.

What Is the South Dakota Rent Calculator?

The South Dakota Rent Calculator is a rental affordability and budgeting tool for renters comparing housing costs with household income. It offers three modes: maximum rent supported by income, affordability of a specific target rent, and annual salary required for a target rent. It also estimates federal taxes and payroll deductions using the tax year 2025 settings coded into the calculator.

A South Dakota rent calculator helps estimate the base monthly rent your income and budget can support. This tool compares a 30 percent gross-income limit, a debt-to-income limit, and an after-tax budget limit. It separately checks a landlord income ratio and estimates take-home pay, housing costs, move-in cash, and Fair Market Rent differences.

The calculator is designed for renters planning a move, comparing listings, checking an income requirement, or estimating the salary needed for a desired apartment. Results are planning estimates. They do not guarantee landlord approval and should not be treated as tax, legal, or financial advice.

How the South Dakota Rent Calculator Formula Works

The calculator starts with gross monthly household income. Annual salary is combined with 12 months of other household income, then divided by 12.

G=S+12O12G=\frac{S+12O}{12}

Here, G is gross monthly household income, S is annual gross household salary, and O is other monthly household income.

Tenant-paid utilities, renters insurance, pet rent, and parking or storage are combined as monthly housing add-ons. If you check that utilities are included, the calculator uses zero for tenant-paid utilities.

A=U+I+P+KA=U+I+P+K

The recommended base rent is the lowest of three affordability limits:

R30=0.30GR_{30}=0.30G
RDTI=Gd−D−AR_{DTI}=Gd-D-A
Rbudget=N−D−V−L−AR_{budget}=N-D-V-L-A
Rrecommended=max⁡(0,min⁡(R30,RDTI,Rbudget))R_{recommended}=\max\left(0,\min\left(R_{30},R_{DTI},R_{budget}\right)\right)

In these formulas, d is the selected DTI ceiling, D is monthly debt, N is estimated monthly take-home pay, V is the savings target, and L is other monthly living expenses. A negative recommended amount is changed to zero.

The landlord screening ratio is calculated separately and does not control the recommended maximum:

Rscreen=GqR_{screen}=\frac{G}{q}

For example, use a $60,000 salary, no other income, no pre-tax contribution, single filing status, no dependents, no debt, no savings target, no living expenses, no housing add-ons, a 43 percent DTI ceiling, and a 3x screening ratio. Gross monthly income is $5,000.00. The 30 percent limit is $1,500.00. The DTI limit is $2,150.00. The code estimates $50,248.50 annual take-home pay, or $4,187.38 monthly, making the budget limit $4,187.38. The recommended maximum is therefore $1,500.00.

Required-income mode uses the same recommended-rent calculation. The code expands a salary range up to 60 times if needed, runs 90 bisection iterations, and rounds the resulting annual salary up to the next whole dollar.

How to Use the South Dakota Rent Calculator: Step by Step

  1. Choose your calculator mode. Select maximum supported rent, test a specific rent, or calculate the annual salary needed for a target rent.
  2. Select your South Dakota county or the available rural South Dakota option. Then choose a studio, one-bedroom, two-bedroom, three-bedroom, or four-bedroom unit.
  3. Enter annual gross household salary and any other monthly household income. You can also enter annual pre-tax retirement contributions.
  4. Select single, married filing jointly, or head of household. Enter the number of dependents claimed, from 0 through 10.
  5. If you are testing a rent or solving for required income, enter the target monthly base rent. Enter rent before utilities and other housing charges.
  6. Select the landlord's published income ratio. Available choices are 2.5x, 3x, 3.5x, and 4x monthly rent.
  7. Enter monthly debt payments, your savings target, and other living expenses. Then select a 36, 43, or 50 percent debt-to-income ceiling.
  8. Enter tenant-paid utilities, renters insurance, pet rent, and parking or storage. Check the utilities-included box if those entered utilities are included in rent.
  9. Enter the requested security deposit, prepaid rent, application or screening fee, moving costs, lease type, and expected annual renewal increase.
  10. Read the acknowledgment, check the box, and calculate the estimate.

The results identify the recommended base rent and the rule that limits it. They also show the landlord screening ceiling, income requirements, estimated take-home pay, total housing cost, DTI, discretionary income, move-in cash, Fair Market Rent comparison, legal benchmarks coded into the tool, and a three-year rent projection.

What Your South Dakota Rent Calculator Result Means

Affordability and landlord screening are separate tests

The recommended maximum rent comes from the 30 percent rule, DTI limit, and after-tax budget. The lowest of those three controls. The landlord screening ratio is reported separately. A rent can therefore satisfy a 3x income requirement while still exceeding the calculator's 30 percent, DTI, or personal budget limit.

Housing burden30% and 50%Classifies total housing cost as a share of gross income
Renewal increase0% to 50%Projects Year 2 and Year 3 rent

HUD Fair Market Rent depends on location and bedroom size

The calculator uses four FY 2025 Fair Market Rent schedules. Minnehaha and Lincoln counties use the Sioux Falls schedule. Pennington uses Rapid City. Meade has its own schedule. Brookings, Brown, Lawrence, and the other rural option use the calculator's rural schedule.

Calculator AreaStudio1 Bedroom2 Bedrooms3 Bedrooms4 Bedrooms
Sioux Falls area$748$882$1,030$1,412$1,730
Rapid City$767$856$1,119$1,490$1,777
Meade County$751$835$1,095$1,506$1,839
Rural schedule$700$780$913$1,200$1,350

For the Fair Market Rent comparison, the code adds tenant-paid utilities to base rent. Renters insurance, pet rent, and parking are included in affordability calculations but not in the displayed gross-rent comparison with Fair Market Rent.

Move-in cash follows the calculator's one-month deposit limit

Move-in cash includes first month's rent, the calculated security deposit, prepaid rent, an application or screening fee, and moving costs. If you choose a deposit above one month's rent, the calculator reduces it to one month. The code notes an exception for special conditions but does not provide an input to model that exception.

The form labels the application charge as a fee per adult. However, there is no visible adult-count field in this calculator. The code therefore falls back to one adult when calculating the screening fee. Households with more applicants should account for that limitation when using the move-in total.

The take-home estimate uses federal taxes only

The calculator sets South Dakota state income tax to $0. Its tax engine uses 2025 federal brackets and standard deductions, a coded $2,000 credit for each of the first three dependents, Social Security at 6.2 percent up to the coded wage base, Medicare at 1.45 percent, and Additional Medicare above the coded threshold.

Pre-tax retirement contributions reduce federal taxable wages in the income-tax calculation, but FICA uses gross salary. Pre-tax contributions are capped at the entered salary. Other monthly household income increases gross household income for affordability tests, but it is not added to the calculator's estimated take-home pay.

The legal information in the tool is coded around a one-month deposit limit except for special conditions, a 14-day deposit-return benchmark, a 45-day itemized accounting benchmark upon request, and 30 days' written notice for a month-to-month rent increase. It also displays no South Dakota rent-control ceiling and no statewide just-cause requirement. Laws can change, so verify current requirements before relying on these figures.

Frequently Asked Questions

How much rent can I afford in South Dakota?

The calculator estimates affordable base rent by taking the lowest of three amounts: 30 percent of gross monthly household income, the rent allowed by your selected DTI ceiling, and the amount available in the after-tax budget. Debt, savings, living expenses, utilities, insurance, pet rent, and parking can reduce the result.

What income do I need for rent in South Dakota?

Use the required-income mode to estimate the annual salary needed for a target base rent. The calculator searches for the salary at which its recommended maximum reaches that rent. It evaluates the same 30 percent, DTI, and after-tax budget rules and rounds the solved salary up to the next whole dollar.

What is the difference between the 30 percent rule and a 3x rent requirement?

The calculator treats the 30 percent rule as an affordability limit and the 3x rule as a separate screening test. The 30 percent formula requires annual gross income equal to 40 times monthly rent. A 3x monthly-income requirement equals annual income of 36 times monthly rent, so the two tests can produce different results.

Does the South Dakota rent calculator include state income tax?

No South Dakota state income tax is deducted in this calculator. The state-tax value is coded as zero. Estimated take-home pay instead subtracts federal income tax, Social Security, Medicare, Additional Medicare tax when applicable, and entered pre-tax retirement contributions from annual salary using the calculator's tax year 2025 settings.

Does other household income count toward rent affordability?

Yes, but only in certain parts of this calculator. Other monthly household income is annualized and added to gross household income for the 30 percent rule, screening ratio, and DTI calculations. It is not added to the take-home-pay calculation, which is based on the annual gross household salary field.

How does the South Dakota security deposit calculation work?

The calculator allows deposit selections from zero through two months of rent, but its calculation caps the deposit at one month's base rent. A 1.5-month or two-month selection is therefore reduced to one month. The code notes that special conditions may be an exception, but the calculator does not model those conditions.

How accurate is the South Dakota Rent Calculator?

The calculator consistently applies the formulas and values contained in its code, but the result is still an estimate. It uses tax year 2025 federal settings, HUD FY 2025 Fair Market Rents, coded legal benchmarks, and your own expense inputs. Actual taxes, landlord rules, fees, lease terms, laws, and household costs may differ.
