Frequently asked questions
Does every city in Maryland have its own per diem rate?
No — only 8 locations have a separately listed GSA rate in Maryland. Every other city or county in the state uses the standard CONUS rate of $110.00 lodging + $68.00 M&IE.
Which city in Maryland has the highest per diem rate?
Ocean City has the highest listed lodging cap in Maryland, at $295.00 a night, compared with $113.00 in Aberdeen / Bel Air / Belcamp.
How do I calculate per diem for a multi-city trip through Maryland?
Use the calculator on each city's page for the nights spent there, then add the totals together — lodging caps and M&IE tiers can differ from one Maryland city to the next, so a single flat rate for the whole trip would be inaccurate.
