Reference & details

How it works

Measure the actual period

Progress is current words divided by your target, times 100. Net growth subtracts the words already present at the start of the period; divide that growth by the counted active or calendar days to find net pace.

Estimate additional days

Remaining words are the target minus the current count, with a minimum of zero. Divide remaining words by positive net pace. With zero or negative growth, no completion estimate is given. Whole days are rounded up.

Allocate sessions separately

Divide remaining words by available sessions. Whole-word base amounts and the remainder form a distribution that adds up exactly. This allocation does not establish how much work you can actually finish in a session.

Example Scenarios

A manuscript growing from 30,000 to 45,000 words over 20 active writing days adds 750 words per writing day. A 90,000-word target has 45,000 words remaining, or 60 more active days at that pace.

A period ending with fewer words has negative net growth. The tool keeps that useful observation and omits a completion forecast.

45,000 remaining words across 40 sessions gives 1,125 words per session. Allocate those sessions on your own calendar.

Common Mistakes to Avoid

Counting an existing draft as new growth

Enter its actual count at the start of the measured period.

Using word growth as a quality score

Record research and revision separately; reducing words can improve a draft.

FAQ

No. Enter your counts and keep a dated log. Browser calculation history can restore entered snapshots, and CSV export provides a separate record.

Progress can exceed 100%; remaining words and additional days become zero. Read and revise the work to judge whether the manuscript itself is complete.

Choose active writing days or all elapsed calendar days, then enter a count on that same basis. The choice labels the pace and adds no multiplier.
