Editable XLSX calculator and Word companion guide, licensed per organisation. Book a demo first and we will walk through it with your own numbers before you decide.
Why this matters
Budgets guessed top-down (‘we have ₹20 lakh, make it fit’) are the ones that overrun and the ones a funder can pick apart. A bottom-up cost, built from how many completed interviews you actually need, is defensible and survives contact with the field.
This calculator does the costing arithmetic for you: it turns your sample and response rate into enumerator-days, prices professional and field effort, layers contingency, overhead and GST in the right order, and reports the total, the cost per completed interview, the split across phases, and three sample-size scenarios side by side.
What it changes
What's inside
- Assumptions, the one tab you edit: study profile, sample, day rates, days-by-phase, field costs, loadings
- Fieldwork engine: sample size becomes contacts, enumerator-days, field-days and cost per interview
- Cost build-up: the budget by phase, with contingency, overhead and GST applied in a fixed order
- Dashboard: headline cost, phase split, and three sample-size scenarios (Lean / Standard / Rigorous)
- Benchmarks: indicative India 2026 day-rates and field norms, with sources
- Word companion guide: the costing logic, the inputs that move the number most, and a worked read-through
