Two calculators, both free and unwalled
Built from the same registry as the rest of this site, so every price and every domain weighting carries the vendor page it was read from. No account, no email field, nothing saved.
Money
Cost calculator
Voucher, retake, the extras the vendor lists, and what renewal wants afterwards. Pick several certifications and it adds them up, with a link to the vendor page behind every figure.
Nothing is estimated that a vendor publishes, and nothing is invented that no vendor publishes. There is no pass-rate guess anywhere in it.
Time
Study planner
An exam date in, a schedule out: which domains in which order, how many questions a day, and which days to sit the practice exams.
Weighted by the vendor's own published domain percentages rather than by an even split, which is the whole difference between a plan and a countdown.
Why neither of these sits behind a form
Everything both tools compute is public: vendors publish their prices and their domain weightings, and anybody can do this arithmetic by hand. There is no secret here to trade for an email address, so asking for one would be charging for something we do not own. Take the answer and go.
The practice is the part we charge for.
Original questions written from the published objectives, each carrying the passage on the vendor's page that the answer rests on.
