Proforma Engine: Run your first projection

## What the Proforma Engine does

The Proforma Engine builds a multi-year financial model from your inputs: purchase price, financing, income, expenses, and exit assumptions. It outputs key metrics (NOI, cap rate, DSCR, IRR, equity multiple) so you can compare deals and stress-test scenarios.

Enter your assumptions

• **Property & purchase** – Address, purchase price, and closing costs.
• **Financing** – Loan amount, rate, term, and type (e.g. interest-only vs amortizing).
• **Income** – Rent, other income, vacancy, and growth assumptions.
• **Expenses** – Operating expenses, CapEx reserve, and growth.
• **Exit** – Holding period and exit cap rate (or sale price).

Interpret the results

• **NOI** – Net operating income; the property's income after operating expenses.
• **Cap rate** – NOI ÷ value; used to compare similar assets.
• **Cash-on-cash** – Annual cash flow ÷ equity invested.
• **IRR** – Internal rate of return over the holding period.
• **DSCR** – Debt service coverage ratio; lenders often require a minimum.

Use the scenario sliders to see how changes in rent, vacancy, or exit cap affect these numbers. For more, see our FAQ on understanding proforma metrics.
