Automating Monthly Revenue Forecasting for Tenant Contracts
In this article, we will discuss a formula for dynamically calculating a monthly revenue series based on tenant contracts, taking into account overlapping contract dates and determining the number of months to be included in the revenue forecast.
Introduction
As a property manager, it is essential to have an accurate and up-to-date revenue forecast for your tenant contracts. This information is critical for financial planning, budgeting, and making informed business decisions. However, manually calculating this revenue series can be time-consuming and prone to errors. In this article, we will explore a formula for automating this process using Excel.
Calculating the Monthly Revenue Series
To calculate the monthly revenue series, we will use the following formula:
=SUMIFS(Revenue\_Range, Contract\_Start\_Date\_Range, >= Start\_Date, Contract\_End\_Date\_Range, <= End\_Date)
Where:
Revenue\_Range: The range of cells containing the monthly revenue amounts for each contract.Contract\_Start\_Date\_Range: The range of cells containing the start dates for each contract.Contract\_End\_Date\_Range: The range of cells containing the end dates for each contract.Start\_Date: The first date of the revenue forecast period.End\_Date: The last date of the revenue forecast period.
This formula uses the SUMIFS function to sum the revenue amounts for all contracts that have a start date greater than or equal to the start date of the revenue forecast period and an end date less than or equal to the end date of the revenue forecast period.
Determining the Number of Months to be Included in the Revenue Forecast
To determine the number of months to be included in the revenue forecast, we will use the following formula:
=MAX(Contract\_End\_Date\_Range) - MIN(Contract\_Start\_Date\_Range) + 1
Where:
Contract\_Start\_Date\_Range: The range of cells containing the start dates for each contract.Contract\_End\_Date\_Range: The range of cells containing the end dates for each contract.
This formula calculates the difference between the maximum end date and the minimum start date of all contracts, and adds one to include the current month in the revenue forecast.
Checking for Contract Date Overlap
To check for contract date overlap, we will use the following formula:
=SUMPRODUCT((Contract\_End\_Date\_Range >= Start\_Date) \* (Contract\_Start\_Date\_Range <= End\_Date))
Where:
Contract\_Start\_Date\_Range: The range of cells containing the start dates for each contract.Contract\_End\_Date\_Range: The range of cells containing the end dates for each contract.Start\_Date: The first date of the revenue forecast period.End\_Date: The last date of the revenue forecast period.
This formula uses the SUMPRODUCT function to count the number of contracts that have an end date greater than or equal to the start date of the revenue forecast period and a start date less than or equal to the end date of the revenue forecast period. If this number is greater than one, it indicates that there is contract date overlap.
In this article, we have discussed a formula for dynamically calculating a monthly revenue series based on tenant contracts, taking into account overlapping contract dates and determining the number of months to be included in the revenue forecast. By automating this process, property managers can save time and improve the accuracy of their revenue forecasts.
