Understanding Results
Formula
Your Mood Index blends four inputs into one clear score. The face rating (1–5) maps to 0, 25, 50, 75, or 100. Each slider (0–10) becomes 0–100. Then we compute:
Mood Index = 0.40 × Face + 0.20 × Energy + 0.20 × Calmness + 0.20 × Motivation
Face reflects your overall feeling right now and carries the most weight. Energy, calmness, and motivation add nuance. Scores range 0–100.
Reference Ranges & Interpretation
80–100 Very Positive • 60–79 Positive • 40–59 Neutral • 20–39 Low • 0–19 Very Low. Look for patterns rather than single‑day swings. If sleep raises your score, aim for a more regular schedule. If late meals or screens pull your score down, experiment with earlier wind‑downs.
Assumptions & Limitations
This tool is not a medical test and does not provide a diagnosis. Mood is influenced by many factors (sleep, medications, illness, stress, context). Use the results to guide small, supportive changes and to inform conversations with a professional if you choose.

What is a mood calculator and how it works
A mood calculator is a simple tool that helps you record how you feel right now and turns that input into a single, easy‑to‑read score. Our mood calculator: track your daily mood and spot patterns uses a quick face rating and three sliders — energy, calmness, and motivation — to build your personal “Mood Index” on a 0–100 scale. The result gives you a clear snapshot of today and, when you save entries, the trend view shows how your mood changes over time.
The goal isn’t to diagnose anything. Instead, it’s to make patterns visible so you can make small, helpful choices: going to bed a bit earlier, taking a short walk, pausing for a few deep breaths, or planning a task that feels doable. Over days and weeks, the picture becomes clearer.
How to use it effectively
Use the calculator once or twice a day at roughly the same time — many people like checking in after breakfast or before bedtime. Rate your overall mood with the faces, then set your energy, calmness, and motivation sliders. If something important happened (a tough meeting, a nap, a workout, a family event), add a short note and tags. Tap “Add Entry” to save it to your device (we don’t store any data on our servers), and watch your chart grow.
You can export a CSV for your own records or to show a clinician if you’re already working with one. Remember: this tool supports self‑awareness; it doesn’t give a diagnosis or replace care.
The Mood Index formula explained
Your Mood Index combines four inputs into a single score. The face rating (1–5) maps to 0, 25, 50, 75, or 100. Each slider (0–10) becomes 0–100. Then we calculate a weighted average:
Mood Index = 0.40 × Face + 0.20 × Energy + 0.20 × Calmness + 0.20 × Motivation
We emphasize the overall face rating (40%) because it’s a quick, human sense of how you feel, while the sliders refine that picture. The score ranges from 0 (very low) to 100 (very positive). It’s normal for the number to move from day to day. What matters most is the pattern over time.
Interpreting your results and patterns
Here is a simple way to read your score:
- 80–100 (Very Positive): You’re feeling upbeat or resilient. Keep the habits that help.
- 60–79 (Positive): Generally good. Aim to maintain your routine.
- 40–59 (Neutral): Mixed signals. Consider light movement or a short focus block.
- 20–39 (Low): Take a gentle step: a walk, water, or 5 minutes of slow breathing.
- 0–19 (Very Low): Be kind to yourself. If this persists, consider speaking with a professional.
The trend view helps you notice anchors — sleep, hydration, meals, social time, or exercise — that nudge your mood up or down. If better sleep improves your score, try pairing the tool with our Sleep Score Calculator and keep the same bedtime for a week to see what changes.
The valence–arousal model in plain English
Psychologists often describe emotions along two broad dimensions: valence (how positive or negative a feeling is) and arousal (how activated or energized it is). In this calculator, valence is influenced by your face rating and motivation; arousal is informed by your energy slider. The combination places your check‑in somewhere on a map: calm‑positive (content), high‑energy‑positive (excited), low‑energy‑negative (down), or high‑energy‑negative (tense).
You might notice that some days are low‑energy but calm — a restful kind of neutral — while others are high‑energy but tense. Both can yield the same overall score for different reasons. Your tags and notes add context so future you can remember what was going on.
Mood vs. stress, energy, and motivation
Mood is not the same thing as stress or energy, though they interact. Stress can be high while mood is good (a big day that feels meaningful) or low while mood is low (feeling overwhelmed). Energy can dip after a poor night of sleep, even when emotions are steady. Motivation often follows sleep, nutrition, and small wins. That’s why the calculator separates these inputs and then blends them into a single, readable score.
Want to look at tension directly? Try the Stress Calculator. If worry and restlessness are more frequent, the Anxiety Calculator can offer a different lens. If low mood is common, the Depression Calculator may help you track patterns to discuss with a clinician.
Non‑medical tips to improve daily mood
Small actions have outsized effects when you repeat them. Consider these gentle ideas (choose one or two):
- Sleep: Keep a consistent bedtime and wake time. Short naps (10–20 minutes) can help without grogginess. See also the Sleep Calculator.
- Hydration: Drink water regularly; mild dehydration can affect alertness. The Hydration Calculator can give you a daily target.
- Movement: Short walks, light stretching, or a few bodyweight sets support both energy and calmness.
- Breathing: Two to five minutes of slow nasal breathing can dial down stress.
- Focus: Pick an easy, single task and finish it. A small win often boosts motivation.
- Connection: A brief chat with a friend or family member can lift mood.
- Mindfulness: Try a 3–5 minute pause. Our Mindfulness Calculator and Meditation Timer can help you start small.
The point isn’t perfection. It’s noticing which simple steps help you feel a little better more often.
Tracking over time: journaling and tags
Tags make your trend line easier to interpret. Pick a few that match your day — calm, stressed, focused, tired, energized, overwhelmed, content, social, grateful — and write a one‑line note. Over weeks, you will likely see recurring pairs: “good sleep + walk = higher score,” or “late meal + screen time = lower score.”
If sleep keeps showing up as a driver, pair this page with our Sleep Score Calculator for a deeper view. If you’re experimenting with exercise, light cardio on rest days or a short Zone‑2 walk can be enough to nudge energy up without feeling drained.
When to seek help and resources
If very low scores persist or your day‑to‑day life is getting harder, consider reaching out to a licensed professional. If you’re in the United States and need immediate support, you can call or text 988 for the Suicide & Crisis Lifeline. For information about stress and coping, the CDC provides guidance, and the NIH has general resources on sleep and wellness.
