Cap Rate Calculator for Contract Documents

Turn lease figures into a clean cap rate. Built for clauses, exhibits, and approval workflows. Save outputs to share with counsel and stakeholders today.

Inputs

Fields are annualized when you choose “Monthly”.
Use Direct NOI when your contract already states NOI.
Market value, purchase price, or appraised value.
%
Adds implied value and required NOI outputs.
Contract rent before vacancy and losses.
%
Use your lease schedule or underwriting assumption.
Parking, CAM recoveries, signage, storage, etc.
Insurance, taxes, maintenance, management fees, utilities.
CapEx reserves for roofs, HVAC, resurfacing, etc.
What is excluded?
NOI typically excludes financing, depreciation, and income taxes. Confirm definitions in your contract schedules.
Use the NOI value defined in your document.
Direct NOI mode
This mode skips EGI and expense rollups. It is useful when an appraisal, exhibit, or schedule already provides NOI.
Tip: For attachments, export CSV for exhibits and PDF for signatures.

Example data table

Use this as a template for schedules or exhibits.

Scenario Value Gross Rent Vacancy Other Income OpEx Reserves NOI Cap Rate
Sample Exhibit $250,000 $30,000/yr 5.0% $1,200/yr $10,500/yr $1,000/yr $18,200/yr 7.28%

Formula used

Detailed method
EGI = (Gross Rent × (1 − Vacancy%)) + Other Income
NOI = EGI − Operating Expenses − Reserves
Cap Rate% = (NOI ÷ Property Value) × 100
Definitions vary across contracts. Align terms with your schedules.
Direct NOI method
Cap Rate% = (NOI ÷ Property Value) × 100
Implied Value = NOI ÷ (Target Cap% ÷ 100)
Required NOI = Value × (Target Cap% ÷ 100)
Use when NOI is already stated in an exhibit or appraisal.

How to use this calculator

  1. Choose Detailed NOI if your document lists rent, expenses, and vacancy.
  2. Choose Direct NOI when NOI is already defined in a schedule.
  3. Enter the property value used for the contract or review memo.
  4. Optionally enter a target cap rate to compute implied value.
  5. Click Calculate and export CSV/PDF for attachments.

Contract-ready inputs and traceable assumptions

Use this calculator to document how a cap rate was derived for a lease file, purchase agreement, or committee memo. Enter the property value from the governing exhibit, then choose either Detailed NOI or Direct NOI to match the document definition. Currency selection standardizes outputs for attachments. Keeping the same assumptions across drafts reduces redlines and supports consistent internal approvals. Add notes in your file on valuation source and effective date.

Income annualization and vacancy treatment

Income fields accept monthly or annual figures, then normalize to an annual basis to avoid mixed-period errors. Gross scheduled rent represents contract rent before losses. Vacancy and credit loss is applied as a percentage reduction to rent, producing effective gross income when other income is added. This mirrors common underwriting schedules and makes each adjustment explicit. For multi-tenant assets, aggregate unit rents before applying vacancy.

Expense discipline and reserves mapping

Operating expenses should reflect recurring, property-level costs such as taxes, insurance, maintenance, utilities, and management fees. Replacement reserves capture planned capital refresh budgets that may appear in condition reports or maintenance annexures. Because definitions differ, align each line item with the contract schedule used in negotiations. Excluding financing and depreciation keeps the NOI figure comparable across buyers. If expenses are reimbursable, include only the net landlord portion.

Cap rate outputs for review memos

Cap rate is computed as NOI divided by value, expressed as a percent. The optional target cap rate adds two decision metrics: required NOI at the stated value and implied value at the calculated NOI. These outputs help reviewers test pricing sensitivity, evaluate renewal scenarios, and justify assumptions in an approval packet. Record the generated timestamp with the memo for auditability. Include the method used so readers understand whether vacancy was applied.

Export controls and record retention

CSV export is suited for spreadsheets, checklists, and exhibit tables, while PDF export provides a fixed snapshot for signatures and document bundles. Run the calculation after finalizing numbers, then attach the export to the relevant clause set or transaction folder. Store the file alongside rent rolls and expense statements so later reviewers can reproduce the cap rate without rework.

FAQs

1) What does cap rate represent in documents?

Cap rate expresses net operating income as a percentage of property value. It helps summarize yield assumptions in exhibits, approval memos, and pricing discussions using a single comparable metric.

2) Should I use purchase price or appraised value?

Use the value referenced by your governing clause or schedule. For acquisitions, that is often purchase price; for renewals or reporting, it may be appraised or committee-approved value.

3) Is debt service included in NOI?

No. NOI typically excludes financing costs, depreciation, and income taxes. If your agreement defines NOI differently, mirror that definition and document the deviation in your file notes.

4) How does vacancy change the result?

Vacancy reduces gross scheduled rent before other income is added, lowering effective gross income and NOI. Because cap rate is NOI divided by value, higher vacancy generally lowers cap rate.

5) When should I choose Direct NOI mode?

Choose Direct NOI when an appraisal, exhibit, or schedule already states NOI and you only need cap rate against a value. Use Detailed NOI when you must build NOI from rent and expenses.

6) Are exports acceptable as attachments?

CSV works well for internal spreadsheets and exhibit tables, while PDF provides a fixed snapshot for signing packets and audit trails. Attach exports alongside rent rolls and expense statements for traceability.
