Certification Renewal Costs Explained: The Four Models You Will Meet

Every certification you might earn from this site’s registry renews in exactly one of four ways, and vendors rarely tell you which one applies until after you already own the credential. Learn the model before you pay the entry fee, and the nine-year cost stops being a surprise you discover through a renewal notice. Here is each model, priced exactly the way the certification’s own page states it, plus the honest total once you decompose the math yourself.

Model 1: Never expires

Microsoft Azure Fundamentals (AZ-900) is the cleanest example you will find of this model. Microsoft’s published expiration policy states that Fundamentals-tier certifications simply do not expire: no renewal assessment, no continuing-education requirement, no annual fee, no window you can miss. Pay $99 once and nine years of holding AZ-900 costs exactly what it cost on day one, nothing more, ever. That permanence carries a real asterisk worth weighing honestly. Your badge stays technically active in 2035 the same as 2026, but the Azure product surface underneath it keeps moving regardless of whether your credential does. Never-expires is a real cost model, not a loophole, and it is the only one on this list where your nine-year total and your day-one total are the same number no matter what you do.

Model 2: Free renewal

This model still puts your credential on a clock. It just does not charge you to reset that clock. Microsoft Azure Administrator (AZ-104) is the clearest case: your certification expires 12 months after you earn it, but starting six months before expiry, a free, open-book, unproctored renewal assessment unlocks on Microsoft Learn. Pass it and your certification extends a year from its existing expiration date, at no charge, with unlimited retakes if you miss the first attempt. Nine years of holding AZ-104 costs you $165 once for the original exam, plus eight of these free annual assessments, or $0 in renewal fees across the whole span. The trade is an unforgiving clock: miss the six-month renewal window entirely and, per Microsoft’s own FAQ, there are no exceptions. Your certification lapses and the only way back is the full $165 exam again.

Cisco CCNA runs the same free idea on a longer cycle. Your CCNA stays valid three years, and the cheapest renewal path costs 30 continuing-education credits you earn through Cisco Live sessions, qualifying training, or other approved activity, at no separate fee from Cisco itself. Log the credits and nine years costs you $0 in dedicated renewal fees; your only real cost is the time you spend tracking activity. Skip that path and retake the $300 exam every cycle instead, and the same nine years runs you $900. Free renewal only stays free if you actually do the free part.

Model 3: Paid maintenance

Two different mechanics both land in this bucket, and telling them apart matters because one is cheaper for you to escape than the other. CompTIA charges a per-cycle continuing-education fee plus a CEU requirement. CompTIA A+ sits in the cheapest CE tier CompTIA offers, $75 per three-year cycle, $225 across nine years if you take the do-it-yourself path. CompTIA Network+ sits a tier higher at $150 per cycle, $450 across nine years, the same tier Security+ occupies. In both cases, earning a higher CompTIA certification renews the lower one automatically and waives its fee, so the ceiling above assumes you stop climbing; keep earning higher CompTIA credentials and your fee heads toward $0. CompTIA A+ vs Network+ covers this exact fee-tier gap in the context of which one to earn first, not just what each costs you to keep.

ISC2’s Annual Maintenance Fee model is the other half of this bucket, and it does not offer you CompTIA’s escape hatch. ISC2 Certified in Cybersecurity charges $50 a year no matter what you do, $450 across nine years, and ISC2 CISSP charges $135 a year, $1,215 across nine years in AMF alone, the largest fixed renewal line this site tracks (tied with CCSP). Unlike CompTIA, stacking a second ISC2 certification does not add you a second AMF (ISC2 charges one fee total across everything you hold), but it also never drops below the per-year rate no matter how efficiently you gather CPEs. Paid maintenance always costs you something. The only real question is whether a harder credential later folds the fee away or simply keeps billing you forever.

Model 4: Retake-only

Some vendors charge you nothing extra to stay certified and offer no free path either: the only way to stay current is sitting the exam again. AWS Cloud Practitioner is the clean example: no annual fee of any kind, and if you never touch another AWS exam, staying certified means retaking the $100 exam every three years, $300 across nine years. Your honest range runs from $0, if you go on to pass any AWS Associate- or Professional-level exam, which automatically recertifies Cloud Practitioner as a side effect, up to that $300 ceiling if you deliberately keep resitting the entry exam instead of climbing. The two entry tickets that cost about the same dollar amount at the door, AZ-900 and Cloud Practitioner, land in completely different renewal models for exactly this reason; AWS Cloud Practitioner vs Azure Fundamentals walks through the full gap if you are choosing between them.

OffSec’s OSCP complicates this model in a way worth understanding before you assume it works like AWS’s version. Since November 2024, passing the OSCP exam awards you two credentials at once: OSCP+, which expires three years from issuance, and OSCP, which does not expire at all. If you earned the certification before that split, you keep a legacy credential that costs you nothing to hold forever, the same shape as AZ-900’s model. Keeping OSCP+ current, by contrast, means requalifying within the three-year window through OffSec’s recertification paths, and OffSec’s own materials describe those mechanics as still evolving rather than fixed, so there is no honest nine-year dollar figure to quote you yet, only the fact that you will requalify twice across nine years if you chase the plus badge specifically. Retake-only is the model where “free unless you retake” and “guaranteed retake” can describe the same vendor at two different points in its own certification’s history.

The comparison-shopping conclusion

Line up the nine-year totals and the four models separate cleanly for you, using only the numbers each certification’s own page states or a plain sum of them. AZ-900 costs you $99 total, forever. AZ-104 costs $165 plus $0 in fees across eight free assessments. CCNA costs $0 in dedicated fees if you log CE credits, versus $900 if you retake instead. A+ runs $225 in CE fees over nine years, Network+ runs $450 over the same span, both on the DIY path. ISC2 CC runs $450 in AMF alone, ISC2 CISSP runs $1,215 in AMF alone. AWS Cloud Practitioner runs $0 to $300 depending on whether you keep climbing. None of these totals include the original exam fee, a separate, one-time number already covered on each certification’s own page and on the ROI Index for the whole registry at once.

The pattern underneath all four models holds regardless of which one a given vendor picked: a sticker price without its renewal model attached is not the real cost you will pay, and the gap between the cheapest and most expensive path for the same credential is frequently larger than the gap between two entirely different certifications. Ask which of these four models applies before you hand over the entry fee, not after your first renewal notice arrives.
