Your hit points are divided into 5 stages. Divide your hp into six, rounding down (min. 1). So your hp may appear as follows:

HP | Stage |

## 22 | 5 (max) |

17 | 4 |

13 | 3 |

8 | 2 |

4 | 1 |

Then the cure spells would say:

*Cure Light Wounds*: Heal 1d8+4 hp or restore your hp or to the first stage value, whichever is greater.

*Cure Moderate Wounds*: Heal 2d8+4 hp or to the second stage value, whichever is greater.

*Cure Serious Wounds*: Heal 3d8+4 hp or to the third stage value, whichever is greater.

*Cure Critical Wounds*: Heal 4d8+4 hp or to the fourth stage value, whichever is greater.

Inflict spells would inflict that much damage or reduce your hp by one or more stages.

Calculating hp stages isn't very complicated, since you only do it when you level up. Electronic sheets would calculate it for you. It provides a framework for wound charts (which I hate but others like). It allows for effects based on your stage as well. (I.e., this effect kills creatures who have fewer hp than their first stage value.)
