Lease vs Month-to-Month Calculator

Typically 10-30% above 12-month lease rate. Higher in high-demand markets (NYC, SF, Boston: 20-30% premium); lower in soft markets (5-15%). College towns spike sharply during summer renewal periods. The premium compensates the landlord for higher tenant turnover risk.

Depends on your stay length. If you'll likely stay 6+ months, a 12-month lease saves money even with break fees. If you'll move within 3-6 months, month-to-month wins despite the 10-30% premium. The crossover point is typically 6-9 months in most US markets.

In limited cases. Most US states allow lease termination without penalty for: military deployment (federal SCRA), domestic violence (most states), uninhabitable conditions, or landlord breach. Otherwise, you'll owe break fees (typically 1-2 months) or remain liable until landlord re-rents (mitigation duty applies in most states).

30 days standard notice in most states. California requires 60 days if you've lived there 1+ year. Massachusetts: 30 days OR one full rent period (whichever longer). DC: 30 days. Always provide written notice, keep proof of delivery (certified mail or email confirmation).

No, except in specific lease provisions. Most fixed leases lock the rent for the entire term. Landlords can raise rent at lease renewal (usually announced 30-60 days before expiration). Rent-controlled jurisdictions (NYC, SF, Berkeley, parts of LA, Newark) cap annual increases regardless of lease type.

Most leases auto-convert to month-to-month if both parties don't sign a new lease. The lease terms continue except for the end date. Some leases require renewal action — read the holdover provisions. In many states, landlord can charge market rent (or rent-control increase) once tenancy becomes month-to-month.

When available, 6-month leases typically come at 5-10% premium over 12-month — middle ground between flexibility and cost. They're less common in major markets but available in college towns, military bases, and corporate housing. Compare 6 × monthly to (12 × monthly) / 2 to see whether the 6-month rate is worth the flexibility.

Someone who stays past lease expiration without signing renewal. Most states impose holdover rent (often 1.5-2× regular rent) until tenant signs new lease or vacates. Some landlords use this aggressively; others ignore short-term holdovers. Always sign a renewal or move out promptly to avoid holdover penalties.
