dev.database-index-size Calculator
Calculates database index storage overhead from table size, column width, and index type, and estimates the read vs write tradeoff. B-tree index overhead is approximately 50–80% of the indexed column data size — adding many indexes speeds reads but slows writes proportionally.
Inputs
Rows
Reference formula or conversion factor shown for context.
Key Bytes
Reference formula or conversion factor shown for context.
Pointer Bytes

Fill Factor
A multiplier applied in the calculation.
Results
index size (MB)
A normalised score comparing the result to a reference baseline.
raw entries (MB)
Sample size or count used in the calculation.
B-tree depth (est.)
The computed depth.
bytes per entry
Sample size or count used in the calculation.
fill factor
A dimensionless multiplier applied in the calculation.
tip
Gratuity amount — the suggested amount to add to the bill as a service tip.
