FRM does not require membership of GARP to use the charter, so free. Although $150 if you want to remain a member of GARP or partcipate in CPE
CFA dues are $275 plus optional local society dues (probably in the region of $200 - $250)
CAIA dues are $350 probably the worst value for money
Personally I also pay dues to the Chartered Institute for Sercurites and Investment in the UK, so my bill comes out to a bit over $1,000 a year. Charged direct to my employer.
Honestly if your employer is not paying, your working for the wrong people or in the wrong profession. To be able to use your charter you have to pay dues, so the charter is relevant to your role ro part of your professional development your employer should pay.
