How this calculator works

Daily rate = monthly rent ÷ days in month. Prorated rent = daily rate × days occupied.

Inputs

  • Monthly rent — full rent for the calendar month.
  • Days in month — 28–31 depending on move month.
  • Days occupied — count move-in day through move-out day per lease convention.

Assumptions

  • Landlord uses a daily proration method (most common in residential leases).
  • Proration applies to base rent only, not fixed fees or utilities.
  • Move-in/out day counting follows your lease (often inclusive of move-in day).

Limitations

  • Some landlords use a 30-day banker's month regardless of calendar days.
  • Second partial month at move-out may need a separate calculation.
  • Rent control units may have specific proration rules.

Example calculation

  1. Rent $1,800, moving in March 15 in a 31-day month.
  2. Daily rate = $1,800 ÷ 31 ≈ $58.06.
  3. Days occupied March 15–31 = 17 days.
  4. Prorated rent ≈ $58.06 × 17 ≈ $987.02.
  5. Savings vs full month ≈ $812.98.
Result: ~$987 prorated rent for 17 days in March

Proration prevents paying a full month when you occupy only part of it. Confirm whether your lease counts the move-in day and which month length is used.

Common mistakes

Using 30 days for every month

Dividing by 30 when the month has 31 days overcharges you slightly. Use the actual days in the move month.

Forgetting move-out proration

If you leave mid-month, you may owe prorated rent for days occupied or pay full month if notice was late—check your lease.

Paying full month plus proration

First month should be either prorated or full—not both. Review your lease ledger before paying.
