Formula used
1) Payable days
Payable Days = minimum(Scheduled Days, Attended Days + Paid Leave Days)
2) Attendance ratio
Attendance Ratio = Payable Days / Scheduled Days
3) Base stipend earned
Base Earned = Base Monthly Stipend × Attendance Ratio
4) Overtime pay
Overtime Pay = Overtime Hours × Overtime Rate
5) Gross stipend
Gross Stipend = Base Earned + Taxable Additions + Non Taxable Additions
6) Taxable income
Taxable Income = maximum(0, Base Earned + Taxable Additions − Pre Tax Deduction)
7) Tax withheld
Tax Withheld = Taxable Income × Tax Rate
8) Net stipend
Net Stipend = Gross Stipend − Pre Tax Deduction − Other Deduction − Tax Withheld
9) Total employer cost
Total Employer Cost = Gross Stipend + (Gross Stipend × Employer Oncost Rate)

Frequently asked questions
1) What does this calculator estimate?
It estimates prorated base stipend, bonuses, taxable and non taxable allowances, deductions, withholding, final net stipend, and total employer cost for one month.
2) Why are attended days and paid leave separate?
Some plans pay approved leave days like normal workdays. Separating them lets you model paid absences without overstating real attendance.
3) Are all allowances treated as taxable here?
No. The tool separates taxable allowance totals from meal, transport, housing, and remote support values so you can compare mixed benefit structures more accurately.
4) What is employer oncost?
Employer oncost represents extra company expense tied to the stipend, such as administration, payroll burden, insurance, or internal benefit overhead.
5) Can I use this for interns, fellows, or trainees?
Yes. The calculator works for any monthly stipend arrangement where pay depends on attendance, allowances, deductions, and optional employer-side costs.
6) What does net retention rate mean?
It shows how much of the gross stipend remains after deductions and withholding. A higher percentage means the recipient keeps more of the gross amount.
7) Why is my net stipend lower than expected?
Common reasons include unpaid days, larger taxable additions causing more withholding, high pre tax deductions, or extra post-tax deductions entered in the form.
8) What is the best way to compare different stipend plans?
Run multiple scenarios by changing attendance, bonuses, tax rates, and allowance mixes. Compare net stipend, employer cost, and effective hourly payout together.
