Estimate core commercial real estate underwriting metrics in seconds. This Argus-style calculator helps you evaluate Net Operating Income (NOI), value from cap rate, annual debt service, DSCR, pre-tax cash flow, and cash-on-cash return from a single input panel.
Tip: This is a fast screening tool. For full institutional underwriting, layer in rent roll details, reimbursements, TI/LC, rollover assumptions, and time-phased cash flows.

If you are searching for an Argus calculator, you are usually trying to answer one core question quickly: “Does this deal make sense before I invest more underwriting time?” This page is designed to do exactly that. It provides an Argus-style, first-pass calculator for commercial real estate investors, asset managers, brokers, and lenders who need clear numbers fast.
At the screening stage, the most important metrics are still the classics: Effective Gross Income (EGI), Net Operating Income (NOI), valuation using a market cap rate, debt service, DSCR, and cash-on-cash return. These metrics are not a replacement for a full institutional model, but they form the practical backbone of disciplined acquisition decisions.
An Argus calculator is generally a shorthand term for a commercial real estate analysis tool inspired by ARGUS-style underwriting logic. In professional practice, ARGUS Enterprise is commonly used to model multi-tenant lease structures, reimbursements, rent steps, expense recoveries, downtime, tenant improvements, leasing commissions, and annual cash flow projections over a hold period.
However, many professionals still need a rapid triage layer before they build a full model. That is where a simplified Argus calculator is useful: it converts key assumptions into decision-ready metrics so you can quickly compare opportunities and prioritize the deals worth deeper analysis.
This calculator follows a straightforward flow:
Because all calculations are on a stabilized annual basis, you can use the outputs to compare one deal against another in a consistent way.
1) Effective Gross Income (EGI)
EGI = (Gross Rental Income + Other Income) × (1 − Vacancy Rate)
2) Net Operating Income (NOI)
NOI = EGI − Operating Expenses
3) Value from Cap Rate
Value = NOI ÷ Cap Rate
4) Annual Debt Service
Calculated with a standard amortizing loan payment formula using interest rate and amortization term.
5) DSCR (Debt Service Coverage Ratio)
DSCR = NOI ÷ Annual Debt Service
6) Pre-Tax Cash Flow
Pre-Tax Cash Flow = NOI − Annual Debt Service
7) Cash-on-Cash Return
Cash-on-Cash = Pre-Tax Cash Flow ÷ Equity Invested
In practical underwriting, no single metric tells the whole story. Use the output set together:
As a rough market convention, many lenders prefer DSCR above 1.20x to 1.30x depending on asset type, location, tenant quality, and rate environment. A DSCR below 1.00x means NOI is not enough to cover annual debt service, which is generally a high-risk signal unless there is a very specific value-add plan with strong evidence.
To get higher quality results from any Argus calculator, focus on assumption quality rather than model complexity. Strong assumptions beat complicated spreadsheets with weak inputs.
Even experienced professionals can make fast-screening errors. The most frequent issues include:
A disciplined approach is to run conservative, base, and optimistic cases. If the deal only works under aggressive assumptions, your downside risk is probably underpriced.
This Argus-style calculator is useful across the CRE capital stack:
Use this tool for initial decision speed. Move to a full model when the deal enters active diligence. At that stage, you should incorporate tenant-level rent schedules, reimbursements, lease options, free rent periods, rollover downtime, TI/LC assumptions, reserve schedules, debt covenants, and exit modeling. A complete underwriting process helps prevent selection bias and overconfidence in initial projections.
No. This is a fast Argus-style screening calculator using high-level assumptions. Full enterprise underwriting software supports far deeper, lease-by-lease projections and institutional reporting structures.
It depends on lender, asset type, and market conditions. Many stabilized loans target at least 1.20x to 1.30x, while stronger coverage may be required in volatile sectors.
You should not rely on a single cap-rate output in isolation. Always compare with sales comps, debt environment, leasing risk, and realistic exit assumptions.
Cash-on-cash can be compressed by high debt service, high equity basis, or large upfront costs. Review financing structure and total invested equity assumptions.
An effective argus calculator is not about producing a perfect number. It is about producing a fast, transparent, and decision-useful range. If your assumptions are realistic and your sensitivity checks are honest, this type of calculator becomes a reliable first filter that improves speed without sacrificing discipline.
