IB Grading Cost Calculator
Enter how many IB grading runs you expect each month and the calculator will show the best-fit Marksy plan, the effective monthly cost per grading, and whether you are under or over a plan limit.
Plan comparison at your volume
This table shows which plan fits your workload and what the implied cost per grading looks like for your current usage.

At your volume
If you are under 5 gradings
The free plan is the lowest-friction way to test the workflow. It is a good fit for a quick proof of value or one-off grading.
If you are between 6 and 50 gradings
The student plan usually becomes the sweet spot. You get a larger monthly ceiling without paying for more capacity than you need.
If you are above 50 gradings
Move up to the ultra tier or contact the team if you are planning a school roll-out and need a broader fit check.
What this means in practice
A good cost calculator should not just tell you the cheapest number. It should help you choose a plan that is actually large enough for your monthly workflow.
