Delaware per diem for FY2027 has 2 listed areas, both on the $74 M&IE tier. In Sussex County, listed as Lewes, lodging is capped at $216 a night in June, July and August and $126 in every other month. In New Castle County, listed as Wilmington, it is $127 all year, exactly the FY2026 figure. Kent County, home to Dover, has no listing and pays the standard $113 of lodging and $68 of M&IE. These rates apply from October 1, 2026 to September 30, 2027. For four nights from July 12, 2027 the federal maximum comes to $1,197 in Lewes, $841 in Wilmington and $758 in Dover. Off season the order flips: Lewes is $1 below Wilmington. Pick any Delaware town in the calculator to compare.
Wilmington's rate stood still
New Castle County kept $127 from FY2026 to FY2027. Meanwhile the national standard rate went from $110 to $113, so the edge a Wilmington, Newark or Middletown address has over an unlisted county shrank from $17 to $14 a night. Over a five-night week that is $70 of extra lodging room, not much once hotel taxes are added. The meals figure is $74, $6 above the standard. Split by meal, the $74 tier gives $18 for breakfast, $20 for lunch, $31 for dinner and $5 of incidentals, which is what gets deducted when a meeting in Wilmington or Lewes provides one of those meals. Both Delaware areas use that same tier, so the meal side of a trip never depends on which of the two counties you sleep in.
Sussex County: summer down, the rest up
The Lewes calendar has two steps. From October through May and again in September the cap is $126, up $2 from last year. In June, July and August it is $216, $5 lower than the FY2026 summer figure of $221. A project team spending the last week of May and the first of June in Sussex County sees the cap jump by $90 overnight on June 1, and the per diem calculator prices each night with its own month.

Dover and the rest of Kent County
Dover is the one Census place of 15,000 people or more in Delaware that falls outside both areas; it is in Kent County. The standard $113 lodging cap applies, with $68 of M&IE, or $51.00 on a day of departure or return. A trip that starts in Wilmington and continues to Dover is paid at the rate of each night's location, not at the rate of the first stop.
Gasoline on the Central Atlantic scale
EIA reports Delaware within its Central Atlantic (PADD 1B) series. Regular averaged $4.363 a gallon in the week of October 5, 2026, against $4.354 for the country. On a round trip between Wilmington and Lewes, the mileage reimbursement at 76 cents a mile is the same whatever the pump price; the mileage reimbursement calculator works it out from the distance.
