Month-to-Month Premium Calculator

Landlords routinely add $100-$400 to rent for month-to-month tenants. It looks steep — but if there's any real chance you'll leave mid-lease, the premium can be cheaper than an early termination fee. This calculator compares total expected rent, flexibility value, and break-even months between a fixed renewal and a month-to-month term.

How the math works

The MTM premium is effectively an insurance policy against paying the break fee. If the break fee is 2 months ($4,000) and the MTM premium is $300/month, the break-even is about 13 months — below that, MTM is cheaper. Above it, the fixed lease wins.

The model also takes a risk haircut for the chance the landlord terminates the MTM early and you eat a moving cost. Landlords rarely exercise this unless they're selling, renovating, or you've been a bad tenant — typical empirical rate is 10-20% per year. Lock the fixed lease if you plan to stay 12+ months and are a good tenant; take MTM only if you legitimately might leave.

How to Use

Enter the proposed fixed-lease rent and the month-to-month premium the landlord will charge.
Enter how many months you expect to stay. Be honest — a job offer, move, or relationship change can shrink this fast.
Set the early termination fee you'd pay if you signed the fixed lease and left early.
The calculator scores both paths and tells you when the MTM premium is cheaper than the break fee.

Frequently Asked Questions

How big is a typical MTM premium?

Most landlords charge 10-25% over the fixed-lease rate. In tight urban markets, it can hit 40-50%. Some leases 'roll over' to MTM at the same rent — those are the exception, not the rule; always read the renewal clause.

When does month-to-month actually pay off?

If you might move within 4-6 months and your break fee is 2 months rent, MTM usually wins. If you're confident you'll stay the full year, signing the fixed lease saves the premium entirely. The tipping point is roughly: break fee ÷ monthly premium = break-even months.

Can the landlord end a month-to-month on short notice?

Yes. Most states allow termination with 30 days notice (some require 60). Losing the unit on 30 days notice and having to rush a move is the real downside of MTM — not the rent premium itself. Factor moving cost into the comparison.

Does MTM hurt renter credit or future applications?

No. Month-to-month shows as a normal tenancy on a future rental application. Some landlords view long MTM histories as slightly less stable than long fixed-term histories, but it is a minor factor next to income, credit, and references.
