Prorated Refund Calculator

Calculate prorated refunds for unused service periods. Determine refund amounts based on total fee, total days, and unused days remaining.

About the Prorated Refund Calculator

When a service contract, subscription, or membership is cancelled before the end of the billing period, a prorated refund returns the unused portion of the prepaid amount. This ensures the customer only pays for the time they actually used the service.

This calculator determines the prorated refund by dividing the total fee by the total service period to find a daily rate, then multiplying by the number of unused days. It accounts for partial months, annual subscriptions cancelled mid-year, and any non-refundable portions.

Prorated refunds are standard in SaaS subscriptions, gym memberships, insurance premiums, lease agreements, and professional service retainers. Understanding how proration works protects both providers and customers from billing disputes.

Legal professionals, business owners, and individuals alike benefit from transparent prorated refund calculations when evaluating obligations, settlements, or compliance requirements. Bookmark this page and return whenever circumstances change so you always have current figures at your fingertips.

Example Calculation

Result: $607.12 prorated refund

Daily rate = $1,200 / 365 = $3.2877/day. Unused portion = $3.2877 × 200 = $657.53. After subtracting $50 non-refundable: $607.53 net refund.

Tips & Best Practices

Proration Methods

The most common proration method divides by calendar days. Some providers use 30-day months (360-day year) for simplicity, which slightly overstates the daily rate. Others prorate by billing cycles rather than days.

Prorated Refunds in Software Subscriptions

Most SaaS companies offer prorated refunds or credits when downgrading or cancelling annual plans. Monthly plans typically run until the end of the billing cycle without a refund. Check the provider's cancellation policy before subscribing.

Handling Disputes

Prorated refund disputes are common. Clear contract language specifying the proration method, effective cancellation date, and any non-refundable amounts prevents most disagreements. Always provide an itemized refund calculation to the customer.

Frequently Asked Questions

What does prorated mean?

Prorated means divided proportionally. A prorated refund returns the portion of a fee that corresponds to the unused service period. If you paid for 12 months but only used 8, you get a refund for the remaining 4 months.

How is the daily rate calculated?

The daily rate is the total fee divided by the total number of days in the service period. For a $1,200 annual subscription, the daily rate is $1,200 / 365 = $3.29 per day.

Are prorated refunds required by law?

It depends on the jurisdiction and service type. Many states require prorated refunds for gym memberships, insurance premiums, and residential leases. Always check your local consumer protection laws.

What about non-refundable fees?

Setup fees, activation charges, and administrative fees are often non-refundable even when the service is prorated. These should be clearly disclosed in the contract before purchase.

How do you prorate a monthly subscription?

Divide the monthly fee by the number of days in that month, then multiply by the number of unused days. For a $30 subscription cancelled on day 20 of a 30-day month: ($30/30) × 10 = $10 refund.

Can I prorate an annual subscription?

Yes. Divide the annual fee by 365 (or 366 for leap years) to get the daily rate, then multiply by the number of unused days. This is common for software, insurance, and membership cancellations.
