STC is calculated by taking the Transmission Loss (TL) values tested at 16 standard frequencies over the range of 125 Hz to 4000 Hz and plotted on a graph. Your curve (what you actually measured) is compared to standard STC reference curves (see appendix).
Once you have your Number of Unit-Months and your Number of Vacant Units, calculating vacancy rate is simple. The formula is Number of Vacant Units / Number of Unit-Months = Vacancy Rate. Using our sample data, 35 / 240 = .1458 or a 14.58% vacancy rate. Calculating the Occupancy Rate is simple once you have the vacancy rate. The formula is 100% â Vacancy Rate Pertentage = Occupancy Rate. Using our sample data, our occupancy rate would be figured as 100% â 14.58% = 85.42%. Having a good idea of your vacancy and occupancy rates will give you an indication of how strong your portfolio is performing. It may also help you determine what you need to do to make your portfolio more profitable.
