Quick answer
$1,800 rent in a 30-day month, moving in on the 10th: $60/day × 21 days = $1,260.
How it works
Prorated rent charges you only for the days you actually live there: monthly rent divided by days in the month, times the days you occupy the place.
Formula
Prorated rent = (monthly rent ÷ days in month) × days occupied

Frequently asked questions
Do all landlords prorate?
Many do, but it's negotiable — ask before signing. Some use a 30-day 'banker's month' regardless of the actual month length.
