Current versus effective rent
Current annual rent per square foot = Annualized rent for the current rent period ÷ Current square feet Spacebase annualizes current-period rent using the lease’s rent frequency: monthly × 12, quarterly × 4, semiannual × 2, or annual × 1. This shows the current rent level; it is not a forecast of the next 12 months with every future increase included. Effective annual rent per square foot = Average annual rent over the term ÷ Average square feet over the term Average annual rent is total recorded rent over the term divided by the term in years. Average area accounts for changes in area over time. If your company uses the current-term setting, the applicable current term is used instead of the original full term.Example: a rent increase
A two-year lease covers 10,000 square feet throughout. Monthly rent is $10,000 in year one and $12,000 in year two. There are no abatements or other rent adjustments.
Effective rent spreads the recorded rent across the term. Current rent shows the rent level for the current period.
Common rent and cost metrics
Effective Monthly Rent / SQFT and its other per-unit variants currently use average annual total cost, divided by 12 and by current area. They therefore may differ from Effective Annual Rent / SQFT divided by 12. The standalone Effective Monthly Rent metric uses rent only. Check the full label before comparing these values.
Space and occupancy metrics
For portfolio effective rent per unit, Spacebase divides the combined average annual rent by the combined average area. This is area-weighted, rather than a simple average of each lease’s displayed rate.
Choose a useful set of metrics
- For rent comparisons, use current annual rent per unit, effective annual rent per unit, and size.
- For budgeting, use current fiscal year rent, operating expenses, and total cost.
- For space planning, use headcount, capacity, utilization, and cost per seat.
- For contract review, pair expiration and notice dates with current rent and total rent over term.
