Lease Renewal Probability Calculator
Empirical same cohort lease-renewal fraction from actual eligible outcomes, not forecast future tenant probability. Censoring/definitions independent.
Description
An empirical renewal fraction summarizes eligible observed lease outcomes.
An empirical renewal fraction summarizes eligible observed lease outcomes.1
Follow-up, censoring and renewal definitions determine which leases enter the denominator. The calculation and input requirements are explained below.
When to use Lease Renewal Probability Calculator
Enter integer eligible renewal count from 0 to 1000000 and eligible expiring count from 1 to 1000000.
How to use Lease Renewal Probability Calculator and how it works
- Prepare the measurements or independently established model inputs described below, with matching units and observation scope.
- Enter the required fields and run Lease Renewal Probability Calculator.
- Read the result fields using the formula, output units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualEligibleRenewedLeaseCount | Actual Eligible Renewed Lease Count. Use the units and matching context stated in the calculation below. | number | Required; integer 0–1000000; finite; other constraints below |
| actualEligibleExpiringLeaseCount | Actual Eligible Expiring Lease Count. Use the units and matching context stated in the calculation below. | number | Required; integer 1–1000000; finite; other constraints below |
Enter integer eligible renewal count from 0 to 1000000 and eligible expiring count from 1 to 1000000. Renewals cannot exceed eligible expiries. Return a fraction from 0 to 1 rather than a percentage or forecast.
renewalFraction=renewedCount/eligibleExpiringCount Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Numeric result under the formula and output units explained above. | number |

"actualEligibleRenewedLeaseCount": 2,

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
