Prorated Rent Calculator (Move-in on the 20th)

Free calculator: Enter monthly rent and your move-in date. We'll calculate rent per day, chargeable days, and your total prorated rent.

Late-month move-ins on the 20th are common for end-of-month turnovers.

Late-month move-ins can look cheaper than they are. Use the correct month length so the daily rate is accurate.

How prorated rent is calculated

Formula: Monthly Rent ÷ Days in Month × Chargeable Days. Chargeable days usually start on your move-in date through the end of the month.

Do landlords have to prorate rent?

It depends on your lease and local rules. Many landlords prorate rent for mid-month move-ins, but it's not guaranteed. This calculator is for convenience and doesn't provide legal advice.

Is prorated rent based on calendar days or 30 days?

Most leases use calendar days in the month, but some use a 30-day standard. If your lease uses a 30-day rule, set the month to any 30-day month for a quick estimate.

Can prorated rent be negotiated?

Sometimes. If you're signing a lease, you can ask. But it depends on demand, timing, and property policies.

Other move-in dates

Example (20th move-in)

Monthly rent $1,800 ÷ 30 days = $60.00 per day.

Chargeable days: 30 − 20 + 1 = 11 days.

Total prorated rent: $60.00 × 11 = $660.00.

What if the month has 31 days?

The daily rate changes because the month length changes. Use the month selector to update the calculation.

Do I count the move-in day as a chargeable day?

Most leases charge from the move-in date through the end of the month, but confirm in your lease.

Use case

Use case: Late-month move-ins when the remaining days are few and totals can be confusing.
