About Spelling Score Calculator

The score adds bonus words to the correct count and divides by the number of words in the main list, so bonus words can push the total above 100%. Reporting the number of words still to revisit next to the percentage keeps the focus on the specific spellings rather than the headline mark.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
