Percentage, amount and fee calculators
Start with the calculation you need. A general percentage differs from a sale discount, grades require weights or credits, and taxes and fees depend on the rules and limits stated on each page.
Which tool fits your task?
Percentages, prices and grades
Choose percentage for part-to-whole ratios or relative changes. Use discount for original and sale prices. Choose grade average or weighted score according to how your marks are combined.
Write an amount or separate its tax
Amounts in words writes a value without changing it. The VAT calculator adds tax or extracts it from a total. The return simulator supports practice with Saudi return components; it does not file anything with ZATCA.
Saudi estimates with a defined scope
Use dependant fees for family budgeting, exit/re-entry for issuance-fee comparisons, and end-of-service for supported private-sector cases. Read exclusions and sources before relying on an estimate.

Separate arithmetic from official decisions
Percentages, discounts and grades are general arithmetic with user-selected weights or scales, not evidence of admission. Saudi fee and regulatory tools are not universal rules; they estimate only their documented cases. Check official sources. These tools submit no application or return to an authority.
Does the calculation depend on a period?
Use the date tools to measure an interval or convert a document date, then check the specialist calculator’s definition of duration. Calendar months and fee-period units are not necessarily interchangeable.
