Our grade measures the official annual billing discount for an individual plan. It does not score output quality, value for money or affiliate commission.
A published, reproducible formula
Annual saving = (1 − annual total ÷ (regular monthly price × 12)) × 100. Both amounts must refer to the same plan, currency, seat count and comparable base allowance. Annual allowances may be allocated differently; check the plan notes.
| Grade | Annual saving |
|---|---|
| A | 30% or more |
| B | 20% to less than 30% |
| C | 10% to less than 20% |
| D | More than 0% to less than 10% |
| E | No annual saving |
Thresholds use the unrounded percentage; displayed percentages are rounded to one decimal place. A $20 monthly plan and $192 annual plan save 20% (grade B), with $192 paid upfront. The $16 monthly equivalent is not a monthly subscription offer.
What we exclude
First-month offers, coupons, affiliate commission, free trial credits, enterprise quotes and cross-provider cost comparisons are excluded. When the provider displays only a dollar symbol, we preserve that symbol without assuming a currency code. Final currency, taxes, promotions and eligibility depend on the provider’s checkout.
Daily checking, accountable review
Official public pages are checked daily while our service is running. Extracted prices require editorial approval before publication. Unchanged approved evidence can be revalidated automatically. A changed page, failed fetch, rejected result or evidence older than seven days pauses the grade. The last confirmed price remains visible with its date and a historical-price notice.
Some websites require JavaScript, sign-in or block automated access. Those results stay unverified until evidence is available. A successful page request does not establish payment acceptance, registration eligibility or access in your region.
