How pro-rata rent is calculated
When a lease starts, ends or changes in the middle of a month, that month's rent is split by days. The usual method divides the monthly rent by the number of days in that month and multiplies by the days charged:
Example: rent of ₹1,00,000 starting on 15 November (30 days) → 16 days are charged → ₹1,00,000 × 16 ÷ 30 = ₹53,333.33.
Actual days or a 30-day month?
Some leases fix every month at 30 days, which gives the same daily rate all year. Others use the actual 28–31 days, so a day in February costs more than a day in March. Use the method your lease specifies — the calculator supports both; a full calendar month is always charged the full monthly rent.
When you'll need it
- Rent commencement in the middle of a month (after a rent-free fit-out).
- Move-out or termination before the month ends.
- An escalation that takes effect mid-month — work out the old-rent days and the new-rent days separately.
Frequently asked questions
How do I calculate rent for a partial month?
Divide the monthly rent by the number of days in that month (or by 30, if your lease uses a 30-day month) and multiply by the number of days you occupy or pay for.
Is GST charged on pro-rata rent?
Yes — GST on commercial rent applies to the amount actually billed, so a part-month bill carries GST on the pro-rata amount.
Does February cost more per day?
With the actual-days method, yes: the same monthly rent is spread over 28 days instead of 30 or 31. With a 30-day month basis, every day costs the same.
