Work out the rent for part of a month, for a move-in or a move-out, or for any dates across several months, in the three common ways of counting a day.

How a day's rent is worked out

A whole calendar month is always the full rent.

Each part month is rounded to a whole rupee. Your rent agreement decides which way of counting applies.

How it works

Three quick steps

01

Enter the monthly rent

The rent for a whole month, in whole rupees.

02

Pick the dates

The first and the last day to charge for, both included. They can run across several months.

03

Choose how a day is counted

By the days in that month, a 30-day month, or a 365-day year. Then copy the result, or share a link that opens with the same numbers.

Good to know

How the numbers are worked out

  • A whole calendar month is always the full rent. Only part months are worked out by the day.
  • Days in that month divides the rent by 28, 29, 30 or 31, whichever that month has.
  • A 30-day month divides the rent by 30, whatever the month.
  • A 365-day year divides twelve months of rent by 365, the same rate all year.
  • Both dates count, so 18 to 30 September is 13 days.
  • Each part month is rounded to a whole rupee.

Questions

Before you use it

The one your rent agreement names, if it names one. If it does not, agree it with your tenant before the first part month. Days in that month is easy for both of you to check on a calendar.
Counting by days in that month spreads February's rent over 28 or 29 days instead of 30 or 31, so each day costs a little more. A 30-day month or a 365-day year gives the same daily rate all year.
Yes. It counts in calendar months, so enter only the days outside a full rent period. For a move-in on 20 September with rent from 5 October, enter 20 September to 4 October.
No. The numbers stay in your browser. Link puts them in a web address only when you copy it, so anyone you send it to sees the same result.
Not on its own. SetURent bills the full rent for every month from the rent start month. For a part month, edit that month's bill to the amount worked out here.
