What belongs in each field?
Tuition is the advertised course price. Mandatory fees are charges you must pay to complete or receive the award. Practical costs are expenses created by your plan, such as travel to an assessed session. Contingency stays separate because it may never be spent.
Avoid double counting
If assessment, certification or tutor support is included in tuition, do not add it again. Check the current course terms before treating an optional upgrade as required.
Use the full cost guide and course comparison alongside the calculation.
