Read a Score's How It's Calculated
What Kaizora's scores summarize, and how to read each component's points, weight, and inputs on a score's page.
Updated
Kaizora computes a published index and three scores of its own. Each is a metric like any other, with a chart, ranges, and habits, and each explains itself on its page under How It’s Calculated.
The Scores
| Score | What it summarizes | When |
|---|---|---|
| Sleep Regularity Index | How consistently you sleep at the same times, from −100 to 100 | At the end of each sleep, over the 14 days before |
| Kaizora Sleep Score | The last 24 hours’ sleep, naps included, from 0 to 100 | At the end of each sleep |
| Kaizora Longevity Score | Long-term health risk factors, such as fitness, activity, sleep, blood pressure, and metabolic labs | Each day |
| Kaizora Financial Health Score | Financial resilience: your savings rate, emergency fund, credit card debt, and net worth trend | Each day |
Today’s value counts what’s recorded so far, so the latest is always current.
Read How It’s Calculated
On a score’s page, How It’s Calculated breaks its latest value into a table, one row per component:
- Component, such as Duration or Savings rate. One marked (required) must have data for the score to have a value.
- Input: what the component looks at, each linking to its metric’s page.
- Value: your input’s value, and Standard: what it’s scored against.
- Points: the component’s score, out of 100.
- Weight: how much it counts in the total.
The score is the components’ points, averaged by their weights. A component with no data is left out and the others count for more, so a missing input never pulls a score down. The Longevity Score needs at least 4 of its 8 components.
The table and the score come from one calculation, so they can’t disagree.
Known Limits
- The Longevity Score summarizes risk; it doesn’t predict a lifespan. Without medication data it can’t allow for treated blood pressure or cholesterol; without a diabetes status, a high HbA1c or fasting glucose is scored as diabetic; and smoking is left out until never having smoked can be told from having no data.
- The Financial Health Score leaves loans out of debt, and recognizes transfers between your accounts only by the Transfer category.
Kaizora has no overall score across everything, and no stress score: averaging unrelated things hides what matters.
