Cash-on-cash = annual cash flow ÷ cash invested; cap rate = net operating income ÷ property value (mortgage excluded from NOI). Everything runs in your browser; nothing is stored. For live figures that update as rents and balances change, track each property in one place.

Your rentals are only part of the picture
