Your numbers
The numbers shown are an example. Replace them with your own.
Coaching centres usually can; schools cannot. If ticked, the cost is compared without GST.
Everyone enrolled and not withdrawn, counted once across branches and batches.
Fee counter, attendance registers, reports, phone calls. Your estimate.
Average salary plus benefits of the people whose time is saved.
Look at your last three months.
Your own assumption. Messaging on Acavya is billed at cost plus up to 10% handling, so not everything disappears.
Total demand for the year.
From reminders and online payment. Set 0 if you do not want to count it.
Receipts, circulars, report copies.
Paper, ink and machine wear, for example 0.50.

How to estimate the payback of an ERP
Enter your students
Fill the number of peak active students. The tool finds your plan and prices it from the current price book.
Estimate the staff time saved
Enter the office hours saved each week across all staff and what that time costs you each month.
Add messaging, fee collection and paper
Enter your monthly spend on SMS, calls and notices and how much you expect to save, the yearly fees billed and the extra share you expect to collect, and the printed sheets you expect to save.
Read the payback and check each assumption
The result shows the payback in days, the net gain and where each rupee of savings comes from. Change any input and the answer updates.
How is the payback calculated?
Payback in days = yearly cost × 365 ÷ yearly savings, rounded up. The yearly cost is the flat yearly price of the plan for your student count from the price book, with GST included unless you can claim input credit on it. Coaching centres usually can; schools cannot. Savings are the sum of four lines you control.
| Line | How it is counted | What to be careful about |
|---|---|---|
| Staff time | Hours saved per week × 52 × monthly cost ÷ 208 working hours | Counts only if you reduce overtime or hiring, or use the time for something valuable |
| Messaging and calls | Monthly spend × 12 × the share you expect to save | Messaging on Acavya is billed at cost plus up to 10% handling, or 0% markup if you connect your own WhatsApp Business account |
| Fee collection | Fees billed in a year × the extra share collected | This is money you were owed anyway; set it to 0 for a stricter view |
| Paper | Sheets saved per month × cost per sheet × 12 | Small, but easy to measure |
Is this a promise of savings?
No. The tool does arithmetic on your inputs. We do not publish a typical saving because we have not measured one across institutes yet. The example numbers on the page are only there to show how the calculation works.
What does an ERP cost for 300 students?
For 300 students the Growth plan costs ₹9,999 a year before GST and ₹11,798.82 with GST, from the current price book, with every feature included. The tool recomputes this for your numbers.
Why does the tool ask whether we can claim GST credit?
Coaching centres usually charge GST on fees and can claim input credit on what they pay for software, so the real cost to them is the amount without GST. Schools with exempt fees cannot, so the cost with GST is the fair comparison. Check with your CA.
Does the calculator send my numbers anywhere?
No. The calculation runs in your browser. If you choose the optional walkthrough form, only the contact details you type there are sent.
What if the payback shows more than a year?
Then, on your inputs, one year of savings does not cover one year of cost. Check the assumptions, especially staff time and fee collection, or consider whether non-money benefits matter to you.
