First-month rent calculator
When a tenancy starts part of the way through a month, the first month's rent is usually charged only for the days the tenant has the place. Enter the monthly rent and the first day, and the calculator shows the amount and how it was worked out.

Result
Rent from 15 November to 30 November 2026: Rs 24,000, for 16 of 30 days.
- First-month rent
- Rs 24,000
- Days charged
- 16 of 30
- Full rent from 1 December 2026
- Rs 45,000
How this was worked out
- November 2026 has 30 days.
- From 15 November to 30 November 2026, counting both days, is 30 − 15 + 1 = 16 days.
- The rent for those days is 45,000 × 16 ÷ 30 = 24,000.00.
- Rounded to the nearest rupee (a half rounds up): 24,000.
- No law that we found says how to charge for part of a month. This calculator counts the actual days in the month, as the Maalik-e-Makaan app does; some agreements count every month as 30 days instead, which gives a different figure.
Worked examples
The rent for the days from the first day to the end of the month, counting both, out of the days in that month.
| Monthly rent | First day | Days charged | First-month rent |
|---|---|---|---|
| Rs 45,000 | 15 November 2026 | 16 of 30 | Rs 24,000 |
| Rs 45,000 | 15 February 2027 | 14 of 28 | Rs 22,500 |
| Rs 50,000 | 20 December 2026 | 12 of 31 | Rs 19,355 |
| Rs 30,000 | 15 February 2028 | 15 of 29 | Rs 15,517 |
How the calculator works
- Count the days from the first day of the tenancy to the last day of that month, counting both.
- Divide by the number of days in that month: 28, 29, 30 or 31.
- Multiply the monthly rent by that share, and round once to the nearest rupee, with a half rounding up.
A tenancy that starts on the 1st pays the whole month. From the next month on, the full rent is due.
This is the rule the Maalik-e-Makaan app uses for the first month, and the calculator runs the same arithmetic, checked against the same test cases.
Is there a legal rule?
We found no statute, court ruling or official guidance that says how to charge rent for part of a month. Charging by the actual days in the month is one convention; another counts every month as 30 days, which gives a slightly different figure in months that are not 30 days long. Whichever you use, write it into the agreement.
The laws we read leave the amount and the due date to the agreement: Punjab’s Rented Premises Act 2009 expects the agreement to state the rent and its due date, and Sindh’s Rented Premises Ordinance 1979 makes rent due by the tenth of the following month when no date is agreed.
