Office and retail rental rates
Rental rates for office and retail space are typically quoted in terms of money per floor-area–time, usually money per floor-area–year. For example, the rate for a particular property may be 290 dollars per square-meter–year ($290/m2·a) (or $29/ft2·a), and rates in the area could range $200/m2·a–$500/m2·a.
In many countries, rent is typically paid monthly even if usually discussed in terms of years.
Example: A particular 200 m2 space is priced at $150/m2·a: (200 m2) × ($150/m2·a) / (12 mo/a) = $2500/month
