Rent vs Buy Calculator
Two paths over the same number of years. Renting builds an investment portfolio out of what would have been a down payment. Buying builds equity through principal paydown plus appreciation, net of carrying costs and selling costs at the end. Honest head-to-head, on your numbers.

Net cost = total out-of-pocket minus equity built (buying) or investment growth on the down payment (renting). Lower number wins on the math alone.

What this calculator misses
The result depends heavily on the assumptions: home appreciation rate, alternative investment return, how long you actually stay. A 1% swing in either appreciation or alternative return can flip the answer. The calculator uses long-term averages; your file uses the next ten years, which the long-term average doesn't guarantee. Two clients with the same inputs but different life timelines often land on different sides.
