Frequently Asked Questions

How much is the CompTIA Linux+ exam cost in 2026?

The comptia linux+ exam cost sits at about $358 USD for a standard XK0-005 voucher in the United States. That covers one scheduled attempt only - courseware, labs, and any retake coverage are billed separately, so plan your real budget around more than just the voucher line item.

What's included in the CompTIA Linux+ voucher price?

A standard Linux+ voucher buys you a single attempt at XK0-005 through Pearson VUE, nothing more. It doesn't bundle a retake, official study guides, or lab access. If you want those extras, look for a CertMaster or exam-prep bundle that explicitly lists them - otherwise you're paying for the attempt alone.

Is there a cheaper CompTIA Linux+ voucher price for students?

Sometimes, yes. CompTIA's academic program offers discounted pricing through participating schools, and some employers or workforce grants cover part or all of the fee. Military tuition assistance can apply too. Always confirm the voucher is valid for the current XK0-005 version before you buy - older SKUs can retire without warning.

How much does a CompTIA Linux+ retake cost?

If you fail on your first try and need to buy a second standard voucher, expect to pay roughly $358 again - so two attempts land around $716 total before taxes. Some exam bundles include a free retake up front, which can work out cheaper than paying for a second voucher after the fact. Do the math before you commit.

Do employers reimburse the CompTIA Linux+ exam cost?

Many do, particularly for IT, DevOps, and systems administration roles where Linux skills matter day to day. Ask your manager or HR about a certification reimbursement policy before you pay out of pocket - some companies only reimburse after a passing score, so read the fine print first.

Are there bundle discounts on the Linux+ voucher price?

CompTIA occasionally sells bundles pairing the exam voucher with CertMaster Learn or CertMaster Practice at a combined price lower than buying each piece separately. Whether that's worth it kind of depends on how much self-study material you already have - if you're already using our practice questions below, a bare voucher might be all you need.

Does the Linux+ XK0-005 cost change internationally?

The $358 figure reflects U.S. pricing. International pricing can differ by region, local currency, and applicable taxes, and testing center availability varies too. Check the official CompTIA store or your local Pearson VUE listing for the exact price where you're testing - don't assume the U.S. number applies everywhere.

Is paying for CompTIA Linux+ worth the cost?

For most sysadmin, DevOps, and cloud support roles, yes - Linux+ is a vendor-neutral credential that verifies real command-line, scripting, security, and troubleshooting skills employers actually look for. Whether it's worth the roughly $358 to you depends on your career stage, though. Someone already deep in Linux administration might get more value from a higher-level credential, while someone newer to the OS often finds Linux+ pays for itself in interview callbacks alone.
