Why rentamor exists
Apartment listings rarely tell the whole story. A unit advertised at $3,000 a month with two months free is not really $3,000 a month. A second unit at $2,750 with no concession might be the worse deal once parking, pet rent, and amenity fees are factored in. Renters get tripped up by these comparisons. Leasing teams want a clean way to present an offer. rentamor closes that gap with a small collection of focused calculators.
Who it's for
- 01Renters comparing two or more apartments, deciding whether to renew or move, splitting rent with roommates, or figuring out what they can afford.
- 02Leasing agents and property teams who want to show prospects a clear net effective number without juggling a spreadsheet on every tour.
- 03Anyone curious about the math behind apartment specials, concessions, and the difference between gross and effective rent.
How the tools work
Every calculator gives you an instant result the moment you enter your numbers. You can verify the formulas in the FAQ on each tool page, and every result shows the breakdown so you can sanity check it against your own spreadsheet or lease document.
The current tools include the Rent Amortization Calculator, the Lease Comparison Calculator, the Roommate Rent Split Calculator, the Lease Renewal vs. Move Calculator, and the Rent Affordability Calculator.
