The same location's rates under other U.S. travel-rate systems:
These three DSSR allowances compensate U.S. government civilian employees assigned to Sofia. The post (cost-of-living) allowance offsets higher overseas costs of goods and services; the hardship differential pays for service where conditions are notably more difficult than in the continental U.S.; and danger pay applies during periods of civil insurrection, terrorism or war. COLA is a percentage of spendable income, while hardship and danger pay are percentages of basic pay -- mobility, HR and payroll teams combine them to compute total overseas compensation.
