CompPilot

Free tools

Rental property calculators

Every metric investors actually underwrite against — cap rate, DSCR, cash-on-cash, BRRRR, and more. Free, no signup, no email gate. Each one shows the formula and a worked example so you can check the math yourself.

Why the rent number matters more than the calculator

Every metric on these pages is downstream of one input: monthly rent. Move rent by $200 and cap rate, cash-on-cash return, DSCR, and cash flow all move with it. A deal that pencils at $2,400 can be underwater at $2,150.

Which is why the most expensive shortcut in real estate investing is guessing at rent — or trusting a listing-site estimate built from asking prices rather than signed leases. CompPilot pulls actual comparable rentals for a specific address, weights them by distance, size, and recency, and returns a defensible rent range plus the full investor math.

Run a free rental analysis on any US address. Rent estimate, comparable rentals, written market memo, and every metric on this page — calculated from real comps instead of assumptions.
