Prorations split shared expenses (like taxes or HOA dues) between buyer and seller based on how many days each party owned the home during a billing period. Use the calculators below to compute exact amounts.
Property Tax — Splits annual property taxes based on how many days the seller owned the home during the tax year. Enter the annual tax amount, the number of days from the start of the tax period to the closing date, and the calculation method. If taxes were prepaid, the seller receives a credit for the unused portion. If taxes are owed, it becomes a debit.
HOA (Homeowners Association) — Splits HOA dues for the current billing period. Enter the dues amount, how often they are billed (monthly, quarterly, or annually), and the number of days into the current billing period as of closing. For example, if monthly dues are $300 and closing is on the 15th, enter 15 days. Most HOA prorations are a debit to the seller for the portion of the period they occupied the home.
Per-Diem (Daily Rate) — Calculates a daily charge or credit multiplied by a number of days. This is commonly used for mortgage interest (e.g., the lender charges daily interest from the last payment through closing), rent adjustments, or utility reimbursements. Enter the daily rate and the number of days it applies.
