SchoolDeck publishes free tools for the arithmetic school offices repeat every term: attendance percentage, fee instalments and late fees, RTE reimbursement, marks-to-grade conversion, pupil–teacher ratio, and generators for transfer certificates, bonafide certificates, fee receipts, hall tickets and ID cards.
They run in your browser and nothing is stored. For anything you will file with a board or hand to a parent, check the output against your own format before using it.
Every school office does the same arithmetic several times a term, usually in a spreadsheet somebody built years ago and nobody quite trusts. These tools do that arithmetic in the open, with the formula stated, so you can check the answer rather than believe it.
None of them require an account. They are not a trial of SchoolDeck and they do not ask for your enrolment before showing a result.
Grouped by the desk that usually asks for them, because that is how the question arrives.
| Desk | What they are working out | Tool |
|---|---|---|
| Accounts | What the term should collect, and what has leaked | Fee collection projection, fee leakage, instalment and late-fee calculators |
| Accounts | What the state owes on RTE admissions | RTE reimbursement calculator |
| Class teachers | Whether a student clears the attendance requirement | Attendance percentage calculator |
| Examination cell | Marks into grades, seating, hall tickets | Grade calculator, seating plan and hall ticket generators |
| Front office | Documents a parent is standing at the counter asking for | Transfer, bonafide and character certificate generators, fee receipts, ID cards |
| Principal | Staffing ratios and next year’s budget | Pupil–teacher ratio calculator, school budget planner |
A calculator that returns a number and hides its working is no better than the spreadsheet it replaced. Worse, in fact — at least somebody at the school could open the spreadsheet.
Attendance percentage is a good example. Whether you count half-days, whether authorised absence is excluded, and whether the denominator is working days or days the student was enrolled all change the answer, and boards differ. Every tool here states which convention it uses and lets you change it, because getting this wrong at the end of a term is expensive to unwind.
Phrased the way they arrive, answered so each one stands on its own.
Yes. They do not require an account, an email address or a demo booking, and there is no usage limit. They exist because the arithmetic is common and getting it wrong is costly.
No. The calculators run in your browser and nothing you type is transmitted or stored. Closing the tab discards it.
Check the output against your board’s prescribed format and your school’s letterhead before issuing anything. The generators produce a correct and complete document, but the format a board accepts is set by the board, not by us.
Checked by the Implementations desk on 1 September 2026. Corrections go in the page, dated, rather than quietly.
Pricing is on the page, in the open, with the counting rule written next to it. Nobody has to book a call to find out what it costs.
