What Is A Pro Rata Premium?

A pro rata premium is a fair and precise way to calculate your insurance cost when you're covered for less than a full billing period—like when you start coverage mid-month or cancel early.

How Pro Rata Premiums Work

• If your cover begins partway through a month or ends early, your insurer calculates the premium only for the days you're actually insured.
• This method prevents overpayment—you only pay for what you use.

Example Calculation

Suppose your monthly premium is R500, but your policy starts on June 20:

• Total days in June: 30
• Days covered: 11 (June 20–30)
• Pro rata premium = (R500 ÷ 30) × 11 = R183.33

When Pro Rata Premiums Apply

• Starting a policy mid-period (e.g., moving into a new home)
• Canceling a policy before its end (you typically receive a pro rata refund)
• Changing coverage mid-term (e.g., adding or removing a car or building)

Benefits of Pro Rata Premiums

• Fairness: You pay only for the days you’re covered
• Flexibility: Easier to adjust or cancel policies without penalty
• Transparency: Clear cost breakdown improves trust

How to Calculate a Pro Rata Premium

The formula is straightforward:

Pro Rata Premium = (Full premium ÷ Total days) × Number of days covered

You can use this calculation for annual or monthly policies.

Tips When Dealing with Pro Rata Premiums

• Always ask if a pro rata clause applies before altering or canceling cover
• Keep track of start and end dates to ensure accurate calculations
