1. Measure the rent difference
Proposed monthly rent minus current monthly rent shows the monthly change; multiplying by 12 shows the annual revenue change if the tenant renews at that amount.

What this calculation answers
How much additional annual rent does the proposed increase create?
What would one vacancy and turnover cost at your assumptions?
How many months of the increase would it take to recover that turnover?
It does not estimate the probability that a tenant will leave or determine whether a rent increase is lawful or advisable.
Renewal economics
Enter the renewal and turnover assumptions.
Planning estimate only. The calculator does not estimate the probability that a tenant will leave, future demand, legal rent-increase limits, required notice, rent control, or whether an increase should be offered.

How break-even works
Separate the upside of renewal pricing from the cost of turnover.
The calculator keeps every assumption visible so you can change the scenario instead of relying on a black-box recommendation.
2. Estimate one turnover
Current rent ÷ 30 × expected vacancy days estimates missed rent. Cleaning, repairs and advertising or leasing costs are then added.
3. Calculate recovery time
When the proposal is an increase, total vacancy and turnover cost ÷ monthly increase shows how many months of extra rent would recover one turnover.
Questions, answered
Rent increase break-even calculator FAQ
Does this calculator tell me whether I should raise the rent?
No. It compares the economics of your own inputs. It does not recommend a rent increase, predict tenant behavior or decide whether a renewal offer is appropriate.
How is the vacancy cost calculated?
The calculator divides the current monthly rent by 30, multiplies that daily amount by the vacancy days you enter, then adds cleaning, repairs and advertising or leasing costs.
What does the break-even period mean?
When proposed rent is higher than current rent, break-even months equal estimated vacancy and turnover cost divided by the monthly rent increase. It shows how long the extra monthly rent would take to recover one turnover at the assumptions entered.
Is the expected market rent verified by Acrelio?
No. The public calculator treats expected market rent as a user-entered planning assumption. Acrelio Pro Market Rent Benchmarking is a separate informational feature with its own data-quality and availability rules.
Does this account for rent control or notice requirements?
No. The calculator is an economic planning tool and does not determine legal rent limits, notice periods or local compliance requirements. Landlords remain responsible for applicable law and lease terms.
Connect the renewal context.
Bring lease timing, market context and vacancy cost together in Acrelio.
Acrelio Pro connects Lease Renewal Radar, Market Rent Benchmarking and Vacancy Cost with the rest of the property record so renewal planning does not live in a standalone calculator.
