About the Office Building Simulator
Model square footage, rent, and occupancy against operating expenses to see NOI and value at your cap rate.
It's built for directional planning: change any assumption and watch the whole projection move, the way a seasoned operator pressure-tests a plan before committing capital. Everything is computed live in your browser — nothing is sent anywhere.
How the Office Building Simulator Works
The model takes 5 assumptions and returns 3 headline metrics plus a full breakdown. Here is exactly what goes in and what comes out — no black box.
The Inputs
| Assumption | Example value |
|---|---|
| Rentable sq ft | 50,000 |
| Rent / sq ft / year | $28 |
| Occupancy | 85% |
| Opex / sq ft / year | $10 |
| Cap rate | 7.5% |
Worked Example
Every figure below is produced by the live model using the example assumptions above. Change any input in the simulator to see your own numbers.

The Operator's Read
Office is a challenged, occupancy-sensitive asset right now — vacancy hits NOI hard and cap rates have widened. Lease term, tenant credit, and TI/leasing costs (not shown) matter enormously. Educational only.
Assumptions & Limitations
- •The model is deterministic: it projects your inputs forward with clear arithmetic, not a Monte-Carlo or probabilistic forecast. It shows one scenario at a time — run several to bracket a range.
- •Defaults are illustrative benchmarks, not your business. Replace every field with your real numbers before drawing conclusions.
- •It abstracts away taxes, financing, seasonality, and one-off events unless a field explicitly captures them. Treat the output as a directional estimate.
- •This is an educational tool, not financial, investment, tax, or legal advice. Validate real decisions with a qualified professional.
