Add up to four apartments next to each other. Add a base rent, lease length, any specials, and recurring fees for each one. The calculator handles the amortization and shows the net effective monthly rent for every option in a single view. Built for renters weighing options and leasing teams modeling concessions.
Side-by-side
Ranking is by all-in monthly cost (effective rent + recurring fees). Lease lengths may differ, but the per-month figure makes them comparable.

FAQ
How rentamor compares apartments of different lengths, what counts toward the cheapest, and what to confirm with the leasing office.
Add the base monthly rent, lease length, any specials (weeks free, months free, percent off, dollar off), and recurring fees for each apartment. The tool calculates the net effective monthly rent and the all-in monthly cost for every lease, then highlights the cheapest one.
Yes. The calculator amortizes every concession across each lease's own length, then surfaces the per-month figure for both effective rent and all-in monthly. That makes a 12-month lease at one building directly comparable to a 13- or 15-month lease at another.
Cheapest is ranked by all-in monthly cost: the net effective rent after concessions plus every recurring fee you add (parking, pet rent, amenity, valet, renter's insurance). It's the closest single number to what you'll pay each month.
You can lay two, three, or four apartments side by side. Four is the upper limit because anything beyond that gets hard to read in a single view, and most renters narrow their search to a short list of finalists by the time they're crunching numbers. Add a lease, fill in the terms, and the comparison summary updates the rankings live.
