Weekly Habit Tracker Calculator

Weekly habit tracker

Add habits, set weekly targets, and tick days you completed them. Submit to calculate completion, consistency, streaks, and a weighted habit index.

Example data table

Formula used

• Done Days: count of checked days (0–7).
• Planned Days: target days per week (0–7).
• Done Capped: min(Done Days, Planned Days).
• Completion %: (Done Capped ÷ Planned Days) × 100.
• Consistency %: (Done Days ÷ 7) × 100.
• Max Streak: longest run of consecutive checked days.
• Weighted Score: (Done Capped ÷ Planned Days) × Weight.
• Habit Index %: (Σ Weighted Score ÷ Σ Weight) × 100, for habits with targets.

How to use this calculator

1. Choose a week start date and keep it consistent each week.
2. Add your habits, then set a target days value for each.
3. Optionally set a weight to prioritize high-impact habits.
4. Tick each day you completed the habit during the week.
5. Click “Calculate weekly progress” to view results above the form.
6. Download CSV or PDF to review, share, or archive your report.

Set realistic weekly targets

Targets translate intent into numbers you manage. A target of 5 days means each missed day drops completion by 20 percentage points. For a new habit, begin at 3 or 4 days, hit that level for two weeks, then increase by one day. Keep targets at 0 for “optional” habits you track without affecting totals.

Measure completion, not perfection

Completion uses done days capped at planned days. If you checked 6 days on a 4-day target, completion remains 100% while the report shows an overage of +2. This avoids rewarding burnout and keeps score tied to commitments. Use the done count to celebrate effort, and use completion to judge whether the plan was realistic.

Use consistency to spot volatility

Consistency is done divided by 7 days, so it highlights week-to-week stability. Two habits can both show 75% completion, yet one may be 6/7 consistent and the other 3/7. When consistency is below 50%, add cues: time, place, and a minimum version that takes under 5 minutes.

Prioritize with weights and Habit Index

Weights turn importance into math. A weight of 2 contributes twice as much as 1 when calculating the Habit Index. For example, if “Sleep by 11” is weight 3 and “Read” is weight 1, a 90% sleep week can offset a 60% reading week. Aim for a Habit Index above 75% when your top habits are weighted higher.

Watch streaks for momentum

Max streak is the longest run of consecutive checked days for each habit. A 4-day streak often signals a working routine, while a 1-day streak suggests you are restarting repeatedly. If streaks are low, pair the habit with an existing anchor, such as “after brushing teeth” or “after lunch,” and keep the first step tiny.

Plan next week using misses and grades

Missed actions equal target minus done, never below zero. If total missed is 6, schedule two 20-minute catch-up blocks or reduce targets by one day. Use the weekly grade as a signal: 90%+ is excellent, 75–89% is strong, 60–74% is building, and below 60% needs a reset. Export CSV or PDF to compare weeks and keep decisions evidence-based. Review notes weekly to capture triggers, barriers, and small process improvements quickly.

FAQs

What is the Habit Index score?

Habit Index is a weighted average of completion across habits with targets. It divides total weighted score by total weight, then converts to a percent. Higher weights make important habits influence the index more.

Why does completion cap at the target?

Capping prevents overdoing from inflating the score. Extra checked days still appear as “over +X”, but completion stays at 100% once the weekly target is met, keeping results tied to the plan you set.

What happens if I set a target to 0?

A target of 0 tracks checkmarks without affecting completion totals or Habit Index. Use it for optional habits, experiments, or habits you want visible in the report while you decide a realistic weekly goal.

How should I choose habit weights?

Use weight to represent impact, not difficulty. Set 1 for normal habits, 2–3 for high-value routines, and 0.5 for low priority. Keep weights consistent week to week so the Habit Index stays comparable.

How do I use the streak metric?

Streak shows your longest consecutive run for a habit. If streak is low, improve cues and reduce friction. If streak is high but completion is low, the habit may be clustered; spread it across more days.

How do the CSV and PDF exports help?

Exports create a portable weekly snapshot for reviews, coaching, or team accountability. CSV works for spreadsheets and trend charts. PDF is a clean report for printing, sharing, or saving alongside weekly planning notes.
