What does YMMV mean?
A disclaimer that another person’s experience or result may differ from yours.
Also written: ymmv · your mileage may vary
The meaning
YMMV means “your mileage may vary.” Online, it warns that a recommendation, opinion or personal result is not universal and that other people may reasonably have a different experience.
What’s the tone?
Informal, cautious and subjective; often considerate, but it can sound dismissive if used to wave away a legitimate concern.
When and how to use it
Add it to reviews, advice, product discussions or personal preferences when you want to share what worked for you without promising the same outcome for everyone. It can stand at the beginning or end of a sentence.
In a conversation
Original examples to illustrate the expression.
Did that study app help you focus?
It helped me organize short sessions, but YMMV if you prefer longer blocks.
The new update improved my battery life—ymmv depending on your phone.
Easy to misread
YMMV does not literally discuss travel or fuel in most online uses. Unlike AFAIK, which limits what the writer knows, YMMV emphasizes that different people can get different results even when the writer’s account is accurate.
A little context
YMMV is established informal written shorthand used in social media, messages and reviews. Oxford and Collins both define it as acknowledging that experiences or opinions differ. The entry does not claim a precise origin date.
