Formula used
This calculator estimates a composite immune score from weighted health factors. Each factor is converted into a 0–100 score, then combined into one result:
Immune Range = score ± range_width
- Factor scores: Age, body condition, vaccinations, parasite control, diet, exercise, sleep, stress, and chronic load.
- Weights: Tuned to total 100% and emphasize body condition, diet, and protection routines.
- Range width: Expands slightly with higher stress and chronic conditions to reflect variability.

Immune score meaning and confidence band
The calculator produces a 0–100 immune score plus a min–max band. The band is wider when stress is higher or when chronic conditions are reported, reflecting greater day‑to‑day variability. Use the score for trend tracking over weeks, not one‑time decisions. Review the factor breakdown table to see which inputs drive change most.
Weight alignment and resilience
Body condition carries 18% of the total weight because large deviations from an ideal target can influence inflammation, mobility, and recovery. Keeping current weight within about ±10% of ideal typically supports steadier scores and a tighter range, especially in older pets. Aim for gradual change, about one percent body weight per week only.
Protection routines: vaccines and parasites
Vaccination contributes 12% and parasite prevention 10%. Consistent schedules reduce avoidable exposures and help the immune system focus on routine maintenance. If you select “not up to date” or “irregular,” expect a visible score drop and priority notes that highlight corrective actions.
Daily drivers: diet, exercise, and sleep
Diet quality is mapped from 1–10 into a 50–100 factor score and contributes 16%. Exercise contributes 12% and is capped so very high minutes do not inflate results unrealistically. Sleep is optimized around ten hours and contributes 10%. Small improvements across these drivers often raise the score more reliably than one large change.
Stress and chronic load management
Stress reduces the stress factor (8%) and also expands the range width, which is bounded from about 6 to 14 points. Chronic conditions slightly lower the chronic load factor and widen the band. If your range stays wide, prioritize calmer routines, enrichment, predictable feeding, and timely checkups, then recalculate monthly to confirm progress.

FAQs
1) Is this a medical diagnosis tool?
No. It estimates an immune resilience score from lifestyle and routine inputs. Use it for tracking trends and discussing questions with a qualified professional, especially when symptoms or chronic conditions are present.
2) Why does the calculator show a range instead of one number?
The range reflects variability. Higher stress and more chronic conditions widen the band, because daily immune performance can fluctuate. A stable routine usually narrows the range over time.
3) What values most strongly affect the score?
Body condition, diet quality, vaccines, and parasite prevention have the largest weights. Exercise and sleep also matter, while age and stress adjust resilience and variability. The factor breakdown table shows your biggest opportunities.
4) How often should I recalculate?
Monthly is a practical cadence for most pets. Recalculate sooner after major changes such as diet adjustments, new exercise routines, travel stress, or updated protection schedules. Save CSV or PDF to compare periods.
5) What should I do if the score is low?
Start with fundamentals: confirm vaccines and parasite prevention, improve diet quality, and support sleep and calmer routines. If low scores persist or your pet seems unwell, consult a professional for tailored guidance.
6) Can I use this for cats and dogs?
Yes, as a general tracking tool. Enter realistic activity, sleep, and stress estimates for the species and age. Ideal weight should be based on professional guidance, because healthy targets vary by breed and frame.
