How the Rent vs Buy Calculator Works
This calculator compares the total cost of renting (rent payments + rent growth) against the net cost of buying (mortgage payments + maintenance + closing/selling costs − home equity built − appreciation gains) over your specified time horizon.
The 5% Rule
A quick mental shortcut: the annual cost of owning a home roughly equals 5% of its value — about 1% property tax, 1% maintenance, and 3% cost of capital (mortgage interest or opportunity cost of your down payment). Divide by 12 and compare to monthly rent for similar properties.
