| Fictional billing record | Amount | Meaning |
|---|---|---|
| Existing pet before the second policy | $54 per month | The previous recurring charge. |
| Existing pet after the discount trigger | $51 per month | The revised recurring charge in this example. |
| New pet, with its quoted discount already included | $36 per month | Add this once; do not discount it again. |
| Ongoing household charge | $87 per month | $51 + $36; a $33 increase over the old one-pet charge. |
| One-time credit appearing on the first bill | $1.50 | The first combined bill is $85.50, but the recurring price remains $87. |
All figures and the credit are invented to demonstrate a billing transition, not a quote or a promise of proration. The second pet adds $36 of premium while the existing policy falls by $3, so the recurring household increase is $33. A one-time credit changes the first payment, not every future month.
If the first bill looks lower than the saved quote, locate the credit before deciding that the premium itself fell. If the second pet’s quote already contains the discount, applying the percentage again understates the commitment. Request the actual adjustment dates and component amounts; do not use this example to predict an insurer’s refund.
