Real Estate Closing Statement Proration Calculation

When buying or selling real estate, closing costs must be allocated fairly between the buyer and seller. Proration is the process of dividing these costs proportionally based on the time each party was responsible for the property. This calculator helps you determine the correct proration amounts for your closing statement.

What is Proration in Real Estate?

Proration is the practice of dividing closing costs between the buyer and seller based on the time each party was responsible for the property. This ensures a fair distribution of expenses that occurred during the ownership period.

Common closing costs that are prorated include:

Property taxes
Homeowners insurance
HOA fees
Utilities
Repairs and maintenance

The proration period typically runs from the date the seller took possession of the property until the closing date.

How to Calculate Proration

The basic formula for calculating proration is:

Proration Amount = (Daily Rate × Number of Days) + Fixed Costs

Where:

Daily Rate = Annual cost ÷ 365
Number of Days = Days the party was responsible for the property
Fixed Costs = One-time expenses that can't be prorated

For example, if property taxes are $12,000 per year and the seller was responsible for the property for 60 days before closing:

Daily Rate = $12,000 ÷ 365 ≈ $32.89/day

Proration Amount = ($32.89 × 60) + $0 (no fixed costs) = $1,973.40

This amount would then be allocated to the appropriate party in the closing statement.

Common Proration Scenarios

Here are some typical real estate proration scenarios:

Scenario	Calculation Example	Result
Property taxes for 45 days	$15,000/year × (45/365) = $1,875.65	Buyer pays $1,875.65
HOA fees for 90 days	$2,400/year × (90/365) = $644.74	Seller pays $644.74
Insurance for 30 days	$1,200/year × (30/365) = $101.37	Buyer pays $101.37

Always verify the exact proration period with your real estate attorney or closing agent, as local laws may affect the calculation.

Frequently Asked Questions

What is the standard proration period?: The standard proration period is from the date the seller took possession of the property until the closing date. This is typically 30-90 days depending on local laws.
Can all closing costs be prorated?: No, some closing costs are fixed and can't be prorated, such as title insurance, appraisal fees, and some attorney fees. These are typically allocated based on other criteria.
How do I know if I owe prorated costs?: You'll receive a closing statement that shows all prorated costs and how they're allocated between you and the seller. Review this carefully with your real estate agent.
What if the proration period is different from the standard?: If the proration period is different (for example, due to a lease or rental agreement), you'll need to calculate based on the actual period of possession. Consult with your real estate attorney.
Can I dispute a prorated cost?: Yes, if you believe a prorated cost is incorrect, you can dispute it with your real estate attorney. Provide documentation of the actual costs incurred during the proration period.
