build.db-index-size Calculator
Estimates database index storage overhead from table row count, index column width, and selectivity, and compares index cost vs. query speedup. Low-selectivity indexes (e.g., boolean columns) consume significant storage while providing minimal query speedup.
Inputs
Rows M
Reference formula or conversion factor shown for context.
Col Bytes

Cost Gb
Age in completed years. Many health and fitness formulas adjust for age.
Results
index size
A normalised score comparing the result to a reference baseline.
monthly cost
The total monetary cost computed for the given inputs.
rows covered
