Month-to-month vs fixed lease worksheet
Enter both offers and compare them across your expected occupancy.
One planning horizon
Both options use the same expected stay.
The worksheet compares month-to-month and fixed-lease costs at each whole month through the fixed term. A known month-to-month rent change is applied chronologically to occupied and entered notice-tail months.
Two fixed-lease paths
Completion and early exit use different terms.
Completed-term concessions apply only at the full fixed term. Before completion, the scenario excludes those concessions and includes only the early-exit obligations you enter.
Cash is not always cost
Refundable deposits remain separate.
The starting-cash estimate includes the first scheduled rent payment, entered upfront nonrefundable charges, and refundable deposit. Deposits are not treated as projected losses, and option-specific moving costs may occur separately.
Formula
How the comparison works
Modeled difference = month-to-month scenario cost - fixed-lease scenario cost.
- The comparison uses only the rent changes, notice obligations, concessions, deposits, and early-exit charges you enter.
- Completed-term concessions apply only when expected occupancy equals the fixed lease term; entered early-exit terms apply only before completion.
- Refundable deposits are shown in starting cash but excluded from modeled nonrefundable cost.
- Common moving costs are excluded; only an entered option-specific incremental moving cost affects that option. Subjective flexibility value, unknown rent changes, and unentered charges are excluded.
Deliberate limits
What the result does not decide
- No overall recommendation or flexibility score
- No predicted rent increase
- No legal conclusion about enforceability
- No unentered fees or common moving costs; enter only option-specific incremental moving costs
Worked scenarios
Twelve-month stay
$2,500 month-to-month rent totals $30,000 over 12 months. A $2,300 fixed lease totals $27,600 when the term is completed and no other charges apply.
Six-month early exit
A lower fixed rent can become more expensive when an entered termination fee, reletting fee, concession repayment, or remaining-rent exposure applies.
Known month-to-month increase
A scheduled replacement rent is applied from its effective month through occupied months and any entered notice-tail months.
Completed-term concession
One free month on a completed 12-month fixed lease subtracts one fixed monthly rent from the completed-term scenario.
Starting cash
The worksheet separately adds the first scheduled rent payment, entered nonrefundable move-in charges, and refundable deposit for each option.
Cost crossover
The timeline identifies exact ties, tie intervals, and changes between adjacent months rather than claiming one option is always better.
Lease-option questions
Is month-to-month rent always more expensive?
No. It often has a higher monthly price, but a fixed lease can cost more for a short stay when entered early-exit obligations apply.
Does the calculator predict future rent increases?
No. It models a month-to-month rent change only when you enable the feature and enter both the known replacement rent and effective month.
How are free months treated?
A fixed-lease free-month or rent-credit concession is included only when the modeled occupancy completes the fixed term.
Are deposits counted as costs?
Refundable deposits are excluded from modeled nonrefundable cost. They appear only in the separate starting-cash estimate.
What is remaining-rent exposure?
It is the number of entered future fixed-rent months included in an early-exit scenario, capped at the months remaining in the fixed term.
Does the lower modeled cost mean that option is better?
No. The result compares entered dollar terms only and does not value flexibility, housing quality, renewal risk, or personal preferences.
