Transparent by design

Assumptions in. Understandable estimates out.

YieldRoof is built for initial deal analysis: enter the assumptions you know, review the breakdown, then stress-test the inputs that carry the most uncertainty.

Results are estimates, not guarantees or professional advice. Read the full Disclaimer.

01
Your deal data stays out of analytics
Calculations run in your browser. Calculator inputs and results are not sent to analytics.
02
Results show their components
Income, expenses, financing, and return metrics are separated so you can see which assumptions drive an estimate.
03
Each strategy gets its own model
Rental, Airbnb, BRRRR, flipping, financing, and debt-coverage questions use focused calculators instead of one generic formula.

Read the deal from more than one angle

Different metrics answer different investment questions

Real estate calculators turn a set of assumptions into comparable measures. No single measure describes the entire deal, so investors commonly review operating income, cash flow, return on invested cash, and debt coverage together.

What may remain each month?

Cash flow

Income − expenses − debt service

Cash flow estimates the dollars left after operating costs and financing. It helps test whether the property may support itself month to month.

How does the property perform?

Cap rate

NOI ÷ property value

Cap rate compares net operating income with property value, making it useful for comparing operating yield without the effect of a particular loan.

What is the return on invested cash?

Cash-on-cash return

Annual cash flow ÷ cash invested

Cash-on-cash return relates annual pre-tax cash flow to the cash put into the deal, so down payment and financing choices matter.

Can projected NOI cover the debt?

DSCR

NOI ÷ annual debt service

Debt service coverage ratio compares property-level income with required loan payments. It addresses coverage, not total investor return.

Financing changes investor return

Cap rate deliberately ignores the loan, while cash flow, cash-on-cash return, and DSCR respond to down payment, interest rate, term, and debt service. Reviewing them together separates property performance from financing structure.

Strategy changes the assumptions

Long-term rentals focus on recurring rent, vacancy, expenses, and financing. Airbnb adds nightly rate, occupancy, and platform costs; flipping emphasizes rehab, holding, and sale costs; BRRRR connects purchase, renovation, rental, and refinance stages.

A calculator is a structured starting point. Verify taxes, insurance, financing terms, property condition, market demand, local rules, and every other material assumption against the actual deal.
