Like to Dislike Ratio Formula
Choose current score, additional likes for a target, or additional dislikes allowed above a minimum rating.
Score mode reports the ratio and the positive rating:
Goal planner mode solves for the extra likes needed to hit a target positive rating, assuming new ratings are likes:
- Likes = current count of likes
- Dislikes = current count of dislikes
- Total = Likes + Dislikes
- Target = desired positive rating expressed as a decimal (90% = 0.90)
- Extra Likes = additional likes required, rounded up to a whole number
Score mode returns likes per dislike, a reduced count ratio, positive percentage and a Wilson 95% binomial score interval. This interval assumes independent Bernoulli sampling; self-selected ratings may be biased and do not establish representative audience approval. The likes planner holds dislikes fixed. For a positive minimum fraction t already met by the current score, the dislikes planner allows floor(likes / t) − current total additional dislikes, holding likes fixed.
Reference Tables
These are mathematical ratio benchmarks, not universal quality grades. Context, audience and sampling affect interpretation.
| Positive rating | Reduced likes:dislikes |
|---|---|
| 0% | 0:1 |
| 50% | 1:1 |
| 80% | 4:1 |
| 90% | 9:1 |
| 95% | 19:1 |
| 100% | 1:0 (division by dislikes is undefined) |
| Starting point | Target | Extra likes needed |
|---|---|---|
| 50 likes / 50 dislikes | 75% | 100 |
| 100 likes / 25 dislikes | 90% | 125 |
| 200 likes / 50 dislikes | 95% | 750 |
| 500 likes / 100 dislikes | 90% | 400 |
Example Problems
Example 1. A video has 480 likes and 60 dislikes. The ratio is 480 ÷ 60 = 8:1. The positive rating is 480 ÷ 540 × 100 = 88.9%.
Example 2. You have 120 likes and 30 dislikes (80% positive) and want to reach 90%. Extra likes = (0.90 × 150 − 120) ÷ (1 − 0.90) = (135 − 120) ÷ 0.10 = 150. You need 150 more likes, with no new dislikes, to hit the target.
FAQ
What counts as a good like to dislike ratio? There is no universal threshold for a good rating. A 4:1 ratio is 80% positive and 9:1 is 90%; compare only relevant audiences and collection methods.
Why does the calculator round extra likes up? A fractional like is not possible. Rounding up guarantees the target percentage is met or exceeded.
What if I have zero dislikes? With at least one like and zero dislikes, division by dislikes is undefined, the reduced count ratio is 1:0, and the positive rating is 100%. With no ratings at all, a percentage cannot be computed.
Does the goal planner assume no new dislikes? Yes. It tells you the minimum likes needed if every future rating is positive. Any new dislikes will raise the number of likes required.
