In short
The answer first
Promotion and relegation connect different levels of a league pyramid. Clubs finishing in designated top positions of a lower division move up, while clubs in designated bottom positions of the division above move down. The exact places, play-offs and licensing conditions are set by each competition rather than by one worldwide rule.
Key takeaways
Promotion rewards league performance by moving a club to a higher division for the next season.
Relegation moves designated lower-finishing clubs to the division below.
Some promotion places are automatic while others are decided through play-offs.
The number of moving clubs differs between countries, divisions and seasons.
Sporting results can be accompanied by licensing, financial, stadium or administrative requirements.
The league-pyramid idea
Unlike a closed league, a promotion-and-relegation pyramid allows membership of a division to change because of sporting results. A club can rise through multiple levels over time, while a struggling top-flight club can fall into the second tier and potentially lower divisions in later seasons.
The movement normally takes effect for the following season. The promoted club joins a stronger division with different opponents, revenues and regulatory requirements, while the relegated club adjusts to the level below.
Automatic places and play-offs
A competition can award promotion automatically to the highest finishers and use play-offs to decide an additional place. Play-offs create a short knockout competition after the regular league table has determined which clubs qualify for them.
England provides a familiar example: in the current Premier League model, the bottom three go down to the Championship, while the Championship's top two and play-off winner take the three available Premier League places. Other countries use different numbers and procedures.
Why relegation battles change the table
A point near the bottom can be as valuable to a club's season objective as a point in a title race. Goal difference and other competition tiebreakers may become decisive when clubs finish level, which is why the exact table rules matter before the final matchday.
There is no universal points target that guarantees survival. Historical averages can be interesting, but the actual safety line is produced by the results of that specific season.
Sporting position is not always the only condition
Professional leagues can require clubs to satisfy licensing, financial, ownership, infrastructure and administrative rules. A club's sporting position may therefore be only one part of formal admission to the next competition.
For a specific league, the governing competition's current handbook or regulations should always override a general explainer. Promotion and relegation are a system, not one globally identical formula.
