Built on the official rate tables in JSP 752 (version 67.1, October 2026). Your unit HR team makes the final call, but this tells you what to expect.
A daily allowance towards getting home at weekends and stand-down, if your home is more than 50 miles from your duty station.
A tax-free contribution to your daily commute. You fund the first few miles of each one-way trip yourself; the MOD pays the rest, up to 50 miles.
Operational Allowance, Council Tax Relief and Longer Separation Allowance added up for one tour.
A fixed sum when you’re ordered to move for a new assignment — for handing back your old home, redirecting post, fitting appliances and more.
A daily allowance when no Service accommodation is available and you have to lodge privately. The rate depends on your rank, location and which charges you’d otherwise pay.
If you’re assigned overseas, this is the flight allowance set for your assignment country.
The number of days and daily amount set for each overseas assignment country, with the most that can be refunded.
What you can claim for an authorised duty journey in your own vehicle, including passengers and sports kit.
An interest-free advance of up to 50% of your salary, capped at £25,000, towards buying a home. You pay an insurance premium while you owe it.
The most CEA can pay towards school fees, per child, so mobility doesn’t disrupt your children’s education.
These calculators are a guide, not an entitlement decision. Eligibility depends on your circumstances and Service commitment type — always confirm with your unit HR admin staff before relying on a figure. Rates from JSP 752 Chapter 3 Section 1.
