North Dakota Rent Calculator
North Dakota taxes wages on a graduated schedule with a 0 percent bottom bracket (top 2.5 percent) and no local wage tax, and limits residential security deposits to one month’s rent with a 30-day itemized 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.

Understanding Rent Affordability in North Dakota
North Dakota has one of the lowest state income-tax burdens in the nation (a 0 percent bottom bracket and 2.5 percent top) and moderate rents, so the binding constraint is usually the screening ratio and after-tax budget rather than the tax code.- North Dakota taxes taxable income on a graduated schedule with a 0 percent bottom bracket (single to $48,475; married to $96,950), then 1.95 percent, 2.27 percent and 2.5 percent at the top, using the federal standard deduction. There is no municipal or local wage income tax.
- The 30 percent affordability standard requires annual income equal to 40 times the monthly rent, while the 3 times monthly ratio most ND landlords publish requires only 36 times. Test case 4 shows the solver returning the income at which the 30 percent rule binds at the Grand Forks-area Fair Market Rent.
- North Dakota limits residential security deposits to one month’s rent, and N.D. Cent. Code 47-16-07.1 requires return (plus accruing interest) with an itemized statement within 30 days after the tenant vacates, with treble damages for bad-faith retention.
- For a month-to-month lease the landlord may raise the rent by any amount by giving written notice at least 30 days in advance; rent cannot be raised during a fixed term. North Dakota has no rent control (preempted) and no cap on the increase size.
- North Dakota has no statewide just cause requirement and no statutory cap on application fees.
- North Dakota’s FY 2025 two-bedroom Fair Market Rent ranges from $928 across much of the non-metropolitan west to $1,419 in Divide County (oil-affected), with Fargo at $1,012, Bismarck at $1,023, Grand Forks at $984 and Minot (Ward) at $1,040, against a $965 statewide average.

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, then North Dakota income tax on a graduated 0 / 1.95 / 2.27 / 2.5 percent schedule on wages minus pre-tax contributions minus the federal standard deduction. North Dakota adds no municipal wage tax.
- Deposit clamping reduces any request above one month’s rent to one month under North Dakota law.
- 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: North Dakota local option taxes and oil-patch rent premiums above FMR in Williston-area counties, which are market conditions rather than statutory rules.

What Is the North Dakota Rent Calculator?
The North Dakota Rent Calculator is a rental affordability and budgeting tool for people considering a rental home in North Dakota. It has three modes: maximum rent supported by income, affordability and approval for a specific rent, and annual salary required for a target rent.
This North Dakota rent calculator estimates affordable base rent by comparing the 30 percent gross-income rule, an after-tax household budget, and a selected debt-to-income ceiling. It separately shows the landlord screening-ratio limit, estimated take-home pay, monthly housing costs, cash needed at signing, HUD Fair Market Rent comparisons, and a three-year renewal projection.
The tool is designed for renters who want more detail than a simple rent-to-income multiple. It accounts for debts, savings goals, living expenses, utilities, renters insurance, pet rent, parking, taxes, deposits, screening fees, moving costs, and expected rent increases.
How the North Dakota Rent Calculator Formula Works
The calculator first combines annual household salary with other monthly household income. It converts that total into gross monthly income. It also calculates housing add-ons. Utilities count only when the utilities-included box is not checked.
Here, G is gross monthly household income. S is annual gross salary, and O is other monthly household income. A is the total of tenant-paid utilities U, renters insurance I, pet rent P, and parking or storage K.
The calculator then produces three affordability limits:
N is estimated monthly take-home pay. D is monthly debt payments. Sv is the monthly savings target. L is other monthly living expenses. d is the selected DTI ceiling of 36, 43, or 50 percent. The lowest of these three limits becomes the recommended base rent.
The landlord screening ratio is calculated separately and does not determine the recommendation:
Here, q is the selected ratio of 2.5, 3, 3.5, or 4 times monthly rent.
For example, the calculator's Fargo test uses a $60,000 salary, $4,000 in pre-tax contributions, $300 in monthly debt, $400 in savings, $1,100 in living expenses, $130 in utilities, and $16 in renters insurance. Estimated monthly take-home pay is $4,142.38. The 30 percent limit is $1,500.00, the 43 percent DTI limit is $1,700.00, and the after-tax budget limit is $2,392.38. The calculator therefore recommends $1,500.00 because the 30 percent rule is the lowest result.
How to Use the North Dakota Rent Calculator: Step by Step
- Choose a calculator mode. Select maximum supported rent, affordability and approval for a target rent, or income required for a specific rent.
- Select your North Dakota county and bedroom size. These fields determine the HUD FY 2025 Fair Market Rent benchmark used in the results.
- Enter annual gross household salary and any other monthly household income. Add annual pre-tax retirement contributions, filing status, and dependents claimed.
- For qualification or required-income mode, enter the target monthly base rent. Choose the landlord's published income ratio from 2.5, 3, 3.5, or 4 times monthly rent.
- Enter monthly debt payments, your savings target, and other living expenses. Then select a 36, 43, or 50 percent debt-to-income ceiling.
- Add utilities, renters insurance, pet rent, and parking or storage. Check the utilities-included option when the entered utility cost should not be treated as your expense.
- Choose the requested security deposit and any prepaid rent. Enter the screening fee and moving costs, then choose the lease type and expected annual renewal increase.
- Check the acknowledgment box and calculate. The tool then displays affordability, income, taxes, monthly budget, move-in costs, market benchmarks, and renewal projections.
In maximum-rent mode, focus on the recommended rent and the named binding rule. Qualification mode evaluates the target rent against screening, housing-cost, DTI, and budget tests. Required-income mode uses a bisection search to find a salary where the recommended affordability amount reaches the target rent, then rounds that salary up to a whole dollar.
What Your North Dakota Rent Calculator Result Means
Affordability and landlord screening are different tests
The screening ratio is an approval benchmark rather than part of the recommended-rent minimum. A 3 times monthly rent screen requires annual household income equal to 36 times the monthly rent. The separate 30 percent rule requires annual gross income equal to 40 times monthly rent.
| Calculator test | How the code uses it |
|---|---|
| 30 percent rule | Sets a base-rent ceiling equal to 30 percent of gross monthly household income. |
| After-tax budget | Subtracts debt, savings, living expenses, and housing add-ons from estimated monthly take-home pay. |
| DTI ceiling | Applies the selected DTI percentage, then subtracts debts and housing add-ons. |
| Screening ratio | Reports a separate landlord approval ceiling and pass or fail result. |
The 30 percent result and housing-cost badge can differ
The 30 percent affordability formula limits base rent to 30 percent of gross monthly income. However, the results badge measures total housing cost, including tenant-paid utilities, renters insurance, pet rent, and parking. A recommended rent can therefore be set by the 30 percent formula while total housing still exceeds 30 percent of gross income.
The code classifies total housing as cost-burdened at 30 percent or more of gross income. It classifies the result as severely cost-burdened when the share is above 50 percent. For example, the Fargo test recommends $1,500 in base rent, but $146 in housing add-ons raise total housing to $1,646, or 32.92 percent of gross income.
Take-home pay uses tax year 2025 assumptions
The calculator estimates federal income tax, Social Security, Medicare, Additional Medicare above the coded threshold, and North Dakota income tax. North Dakota taxable income uses salary minus pre-tax retirement contributions and the federal standard deduction. The coded state rates are 0, 1.95, 2.27, and 2.5 percent, with no local wage tax included.
Federal tax also applies a $2,000 credit for each of the first three dependents entered, with federal tax prevented from falling below zero. Pre-tax retirement contributions reduce federal and North Dakota taxable income in the code, but they do not reduce salary used for Social Security or Medicare.
Other monthly income is handled differently from salary
Other monthly household income is annualized and added to gross household income. It can therefore increase the 30 percent limit, DTI limit, and screening ceiling. However, the take-home-pay function is calculated from salary only. Other monthly income is not added to estimated net monthly pay used by the after-tax budget formula.
Move-in costs use a one-month security deposit cap
The calculator limits the security deposit used in its estimate to one month's base rent. If 1.5 or two months is selected, the calculated deposit is reduced to one month. Move-in cash includes first month's rent, the capped deposit, prepaid rent, application or screening fees, and entered moving costs.
There is an important interface limitation. The screening fee is labeled as a fee per adult, and the output refers to fees for all adults. However, the visible calculator has no adult-count field. The code therefore falls back to one adult when calculating the screening-fee total.
Fair Market Rent and renewal figures are comparison tools
The calculator selects a HUD FY 2025 Fair Market Rent from its county and bedroom tables. It compares that benchmark with base rent plus tenant-paid utilities. It also calculates the annual income required at the chosen screening ratio for both the subject rent and the selected Fair Market Rent.
The renewal section uses the entered expected annual increase. Year 1 equals the starting base rent. Year 2 applies one increase, and Year 3 compounds the increase twice. Total three-year rent equals 12 times the sum of the three monthly figures. The input is limited to an increase between 0 and 50 percent.
These figures are estimates for budgeting and comparison. Actual taxes, rental criteria, fees, utility bills, lease terms, rent changes, and legal rights may differ. The calculator does not guarantee rental approval and does not provide financial, tax, or legal advice.
Frequently Asked Questions
How much rent can I afford in North Dakota?
The calculator estimates affordable base rent using the lowest of three limits: 30 percent of gross monthly income, an after-tax household budget, and the selected debt-to-income ceiling. Debts, savings, living costs, utilities, insurance, pet rent, and parking can reduce the amount supported by the budget or DTI tests.
What income do I need for rent in North Dakota?
Choose the income-required mode and enter your target base rent. The calculator searches for an annual salary where its recommended affordability amount reaches that target. It can expand its search range up to 60 times and then performs 90 bisection iterations before rounding the required salary up to a whole dollar.
What is the 3 times rent rule in North Dakota?
In this calculator, a 3 times rent screening rule means gross monthly household income must equal at least three times the monthly base rent. That is the same as annual household income equal to 36 times monthly rent. The tool treats this as a separate landlord screening test rather than its affordability recommendation.
Is the 30 percent rule the same as the 3 times rent rule?
No. The 30 percent rule allows base rent equal to 30 percent of gross monthly household income, which corresponds to annual income equal to 40 times monthly rent. A 3 times screening ratio corresponds to 36 times monthly rent. The 30 percent formula is therefore the tighter income test at those settings.
Does the North Dakota Rent Calculator include taxes?
Yes. The calculator estimates 2025 federal income tax, Social Security, Medicare, Additional Medicare where applicable, and North Dakota individual income tax. These deductions are used to estimate salary take-home pay for the after-tax budget test. The calculation is simplified and does not represent every possible deduction, credit, or tax situation.
Does the calculator include utilities and other housing costs?
Yes. Tenant-paid utilities, renters insurance, pet rent, and parking or storage are included as monthly housing add-ons. They increase total housing cost and reduce the rent supported by the DTI and after-tax budget formulas. If utilities are marked as included, the entered utility amount is treated as zero.
How accurate is the North Dakota Rent Calculator?
The result is an estimate based on the values and assumptions coded into the calculator. Accuracy depends on the information entered and how closely the tax, expense, screening, and rent assumptions match your situation. Actual landlord decisions, taxes, fees, utility costs, rent increases, and lease terms can produce different results.
