Each Member Company pays an annual subscription, which is based on their declared UK rail turnover in the last financial year for which figures are available.  
 
Subscription arrangements are reviewed annually by RIA’s Finance Committee and Board. 
 
Subscriptions are invoiced to new members on commencement of membership and to existing members in the early part of the membership year. When a company joins after April, the subscription for the remainder of a financial year is charged proportionately.

Different fees apply to bands of turnover: 

• The fee for a UK rail industry turnover of up to £1M is a flat reduced charge of £900 (given that the company is not owned by a company with a turnover of more than £50 million, in which case see next band).
• If the company's UK rail turnover is less than £2m, and is owned by a company with a turnover of more than £50 million, the fee is charged at a flat charge of £1,800.
• If the company's UK rail industry turnover exceeds £2M,  the rate is £860 per £1M of turnover up to £19.9M.
• Turnover between £19.9M and £51.9M is charged at the reduced rate of £845 per £1M.
• Turnover above £51.9m but below £229.4M is charged at a further reduced rate of £50 per £1M. 
• Finally, turnover above £229.4M and up to £671.5M is charged at £8 per £1M.
• There is no further charge for turnover beyond £671.5M.
