TA/DA calculation for pharma field staff: how it works, with a worked example
Travel allowance (TA) and daily allowance (DA) make up most of a medical representative's expense claim, and most of the arguments about it. The arithmetic is simple. What goes wrong is the inputs — which distance, which day type, which trip. This page explains the standard HQ, ex-station and outstation structure, walks through a month's calculation, and lists the rules that keep a claim honest.
The three day types: HQ, EX and OS
Almost every Indian pharma expense policy classifies each working day by where the representative worked relative to their headquarters. The day type decides the daily allowance, and often how travel is paid.
| Day type | What it means |
|---|---|
| HQ (headquarters) | Field work within the headquarters town. The lowest daily allowance; travel is often a fixed local conveyance or a small per-km amount. |
| EX (ex-station) | Field work outside headquarters, returning home the same day. A higher daily allowance plus travel for the distance to the ex-station town. |
| OS (outstation) | Field work that requires a night away from headquarters. The highest daily allowance, travel for the journey, and usually a hotel or night-stay allowance. |
How TA and DA are calculated
- Daily allowance = the fixed amount for the day's type (HQ, EX or OS), taken from the policy for the representative's grade.
- Travel allowance = distance × the per-km rate for the travel mode in the policy, or a fixed fare for public transport.
- Night stay = a fixed or capped amount for each outstation night, where the policy pays one.
- Other heads — phone, courier, stationery — are usually a fixed monthly amount or reimbursed against a bill.
A worked example
Suppose a representative's policy pays ₹200 DA on an HQ day, ₹350 on an EX day and ₹600 on an OS day, ₹3 per km for travel on their own two-wheeler, and ₹1,000 per outstation night. In a month they work 14 HQ days, 6 EX days of 60 km round trip each, and one 2-day outstation trip of 220 km in total.
DA: 14 × ₹200 + 6 × ₹350 + 2 × ₹600 = ₹2,800 + ₹2,100 + ₹1,200 = ₹6,100. TA: (6 × 60 + 220) km × ₹3 = 580 km × ₹3 = ₹1,740. Night stay: 1 × ₹1,000. Total TA/DA for the month: ₹8,840, before any fixed monthly heads.
Where TA/DA claims go wrong
| Problem | The rule that prevents it |
|---|---|
| Kilometres rounded up or invented | Distance comes from a defined source — the GPS trail, an admin-approved route distance, or the actual sequence of visits — and the claim records which one was used. |
| A local day claimed as outstation | The day type follows the route actually worked, not a box the representative ticks. |
| An outstation route selected but not worked | No outstation calls on the route means no outstation allowance and no outstation kilometres for that day. |
| Two trips claimed for one day | Only one route pays per day, so travel and daily allowance always describe the same trip. |
| Every line re-checked by finance | When the amounts are computed from recorded work, review shifts to exceptions instead of every row. |
How PharmaMonitor calculates TA/DA
In PharmaMonitor the app never computes money; the server does. When the representative finalises the day, the expense sheet comes back already calculated: daily allowance from the day type of the route worked, and travel allowance from a distance ladder — GPS trail, admin-approved route distance or actual visit chain — with the source recorded on the sheet. Only one route pays per day, and an outstation route that was not called on pays neither outstation allowance nor outstation kilometres.
Rates and heads are configured per company by role, expense head and station type, and claims move from the reporting manager to finance for approval.
Frequently asked questions
What is HQ, EX and OS in pharma?
They are the three standard day types for field staff. HQ is work within the headquarters town, EX (ex-station) is work outside headquarters with a same-day return, and OS (outstation) is work that needs a night away. Each pays a different daily allowance.
How is DA calculated for medical representatives?
Each working day pays a fixed daily allowance according to its day type — HQ, EX or OS — at the rate set for the representative's grade. The month's DA is the sum across all working days.
How is TA calculated per km?
Travel allowance is the distance travelled multiplied by the per-km rate for the travel mode in the company's policy. The important question is which distance is used — a GPS trail, an approved route distance or the actual visit sequence — and that the claim records the source.
What is a typical TA/DA rate in Indian pharma?
There is no single standard. Rates vary by company, grade, region and travel mode, and change with policy revisions. The figures in the worked example on this page are illustrative only.
Can TA/DA be calculated automatically?
Yes, if the day's route and visits are recorded. In PharmaMonitor the server computes both TA and DA when the representative finalises the day, so the representative does not type allowance amounts.
