Formula & Methodology

3 formulas

Rent Increase Percentage

Increase % = (New Rent − Old Rent) / Old Rent × 100

The rent difference divided by current rent gives the percentage change; it is undefined when current rent is zero.

Gross Rental Yield

Gross Yield = Annual Rent / Property Value × 100

Gross yield uses proposed monthly rent multiplied by 12 and the number of units, divided by property value before vacancy and expenses. Net yield applies entered vacancy and annual operating expenses; debt and unentered costs are excluded.

Rent-to-Income Ratio

Rent-to-Income = Monthly Rent / Gross Monthly Income × 100

Rent divided by the entered monthly income is a descriptive ratio, not a prediction of payment behavior.

Methodology

This calculator compares user-entered rent, income and property assumptions, turnover scenarios, projections and selected published guidelines. It does not determine coverage or legal compliance.

Assumption: Landlord Rent Increase Calculator relies on the values the user enters and does not independently verify rent, income, expenses, property value, legal status, lease terms, or local law.

Assumption: CPI, vacancy, expense growth, market cap rate, and turnover-cost inputs are planning assumptions; the tool does not fetch current market data or forecast tenant behavior.

Assumption: The projection assumes rent and expenses grow annually at the entered rates, scheduled occupancy follows the entered vacancy rate, and no taxes, financing, depreciation, or income-tax effects are modeled.

Limitations & guidance

Yield and value-impact outputs are not cash-on-cash returns, tax advice, or a valuation; they exclude financing, depreciation, taxes, and many property-specific costs unless included in annual expenses.

Rent-control laws vary by jurisdiction and may change. The selected published guideline is a simplified comparison; confirm its effective date, coverage, prior increases, exemptions and any other adjustments with the relevant authority before acting.

This tool does not constitute legal, tax, housing, or investment advice and creates no attorney-client relationship. Consult a licensed professional for a specific property or tenant situation.

Professional guidance: Landlord Rent Increase Calculator is for educational planning only and is not legal, tax, housing, or investment advice. Confirm the applicable cap, notice period, exemptions, and lease terms with your local housing authority or a licensed professional.

Key Terms Explained

Rent Control Limit A rent guideline may limit increases for covered tenancies, subject to the relevant date, exemptions and other rules.

CPI (Consumer Price Index) A measure of inflation published monthly by the Bureau of Labor Statistics. Many rent-control ordinances tie the allowable increase to a local or regional CPI figure.

Gross Rental Yield Annual rent income divided by property value, expressed as a percentage. It measures the top-line return before expenses and is useful for comparing properties.

Net Rental Yield Annual effective property rent less entered expenses, divided by property value.

Rent-to-Income Ratio Monthly rent as a percentage of a tenant's gross monthly income. The standard threshold is 30% — above this, a tenant is considered rent-burdened and carries higher non-payment risk.

Vacancy Turnover Cost Lost rent during the entered vacancy period plus the entered reletting costs.

Hypothetical CPI comparison

Current Monthly Rent $2,400 Local CPI Rate 3.5% AB-1482 Cap Formula CPI + 5%, max 10%

A hypothetical 8.5% comparison on $2,400 is $204 per month. It does not establish coverage or the applicable legal limit.

Turnover Break-Even Analysis

Current Monthly Rent $1,800 Proposed New Rent $2,000 Estimated Turnover Cost $3,000

$3,000 divided by an additional $200 per month is 15 months. First-year receipts depend on the entered vacancy and reletting assumptions.

Marcus

Tenant Affordability Check

Tenant Monthly Income $5,500 Current Monthly Rent $1,600 Proposed New Rent $1,750

The ratios are 29.1% before and 31.8% after. These ratios do not predict the tenant’s behavior.

Compare a Proposed Rent Increase

4 chapters · 2 min read

Compare the financial effects of a proposed rent and review applicable published guidelines only after confirming the date and tenancy coverage.

The True Cost of a Vacancy

Enter your own vacant months, alternative rent and reletting costs to compare first-year receipts. The tool does not estimate a tenant’s departure probability.

Rent Control: Know Your Limits Before You Send the Notice

The selected published guideline is only a starting point. Confirm dates, coverage, exemptions, previous increases and any separately authorized adjustments with an authoritative source.

The Affordability Line and Tenant Risk

The rent-to-income ratio describes rent relative to entered income. It does not predict an individual tenant’s payment or housing decisions.

Rental Yield and Long-Term Investment Returns

Property yields depend on the entered units, vacancy, expenses and property value. They exclude debt and unentered costs.

Questions

Frequently Asked Questions

8 questions

How much can I legally raise rent?+

How much notice must I give before raising rent?+

Notice requirements depend on the lease, jurisdiction and circumstances. Check the applicable rules before sending notice.

What is a reasonable annual rent increase?+

No single increase fits every property. Compare your assumptions, tenant circumstances and applicable rules.

It is proposed rent divided by the entered monthly income. A ratio is descriptive and does not predict an individual tenant’s payment behavior.

Can I raise rent during an active lease?+

Lease terms and applicable rules determine whether and when an increase may take effect. Verify them for the tenancy.

What does CPI + 5% mean in California?+

The CPI-based preset is a hypothetical comparison, not a determination of California coverage or an applicable legal limit.

How do vacancy costs compare to rent increases financially?+

Compare first-year receipts using your own alternative rent, vacant months and reletting costs. The calculator does not predict departure.
