Common when moving in or out mid-month.

How the calculation works

When you move in or out mid-month, you pay only for the days you actually occupied — the prorated (pro rata) rent. It's a simple rule of three:

prorated = (rent ÷ days in month) × days occupied

Step-by-step example

Rent of R$1,500, moving in on the 21st of a 30-day month (10 days occupied):

  • Daily value: 1,500 ÷ 30 = R$50
  • Prorated: 50 × 10 = R$500

Common questions

The move-in day is usually counted. Months have 28–31 days, so the daily value shifts a bit by month — use actual days for the fairest split. HOA fees and property tax are typically prorated the same way.

Examples

  • R$2,400, leaving on the 10th (31-day month): 2,400 ÷ 31 × 10 ≈ R$774.19.
  • R$1,800, moving in on the 16th of a 30-day month (15 days): R$900 (half).

Frequently asked questions

30 days or actual days?

Depends on the lease; the fairest standard is the actual days of the month (28–31).

Does the move day count?

Usually yes, the move-in day counts. Best to state it clearly in the lease or agreement.

Are HOA and property tax also prorated?

When charged with the rent, they are usually split by the same occupied days.
