Variable Limits Explained
What Counts as a Variable?
Each Column in Your Data File = One Variable
Examples:
Created Variables Count Toward Limit
Variables You Create in MixModeler Also Count:
Example:
Uploaded: 15 variables
Created saturation curves: 5 variables
Created adstock variables: 3 variables
Total: 23 variables (exceeds Free plan limit of 20)
Solution: Upgrade to Professional plan
How to Work Within Variable Limits
Strategy 1: Combine Similar Channels
Instead of:
Facebook_Feed
Facebook_Stories
Facebook_Reels
Instagram_Feed
Instagram_Stories
Instagram_Reels(6 variables)
Use:
Meta_Social(1 variable)
Trade-off: Less granular insights, but stays within limits
Strategy 2: Exclude Low-Impact Variables
Prioritize: ✅ Major marketing channels (TV, Digital, Radio) ✅ KPI variable ✅ Key seasonality indicators
Consider Excluding: ❌ Experimental channels with minimal spend ❌ Variables with zero variance ❌ Redundant control variables
Strategy 3: Use Fewer Seasonality Dummies
Instead of 12 month dummies:
Month_Jan, Month_Feb, ..., Month_Dec(12 variables)
Use 4 quarter dummies:
Quarter_Q1, Quarter_Q2, Quarter_Q3, Quarter_Q4(4 variables)
Savings: 8 variables
Model Limits
Free Plan: 3 Active Models
What This Means: You can have up to 3 saved models at a time
Workaround:
Delete old models to make room for new ones
Export models to Excel before deleting (preserve results)
Reimport later if needed
Professional & Business: Unlimited Models
Build as many as you need:
Test multiple variable combinations
Compare different adstock rates
Build separate models for different KPIs
Keep historical model versions
File Size Limits
Why File Size Matters
Larger Files Have:
More observations (longer time series)
More variables (columns)
Richer data (more precision in numbers)
Typical File Sizes:
What If Your File Exceeds Limit?
Options:
1. Reduce Variables Remove less important columns
2. Reduce Observations Focus on recent time period (last 2-3 years)
3. Save as CSV CSV files are smaller than Excel (.xlsx)
4. Upgrade Plan Professional (20 MB) or Business (50 MB)

FAQs
Q: What happens if I exceed variable limit?
A: You won't be able to add more variables to models. Existing models continue to work. To add variables, either:
Remove some existing variables
Upgrade to higher tier
Q: Are variable limits per model or total?
A: Variable limits apply to your data file, not per model. If your uploaded file has 50 variables, that counts against your limit regardless of how many you use in each model.
Q: Can I try Professional before committing?
A: Yes! Start with Free plan to evaluate. Upgrade anytime. We offer 30-day money-back guarantee on annual plans.
Q: Do observations (rows) count toward any limit?
A: No! Observations are unlimited on all plans. Only variables (columns) are limited.
Q: What's included in "Priority Support"?
Professional: Email support with 48-hour response time
Business: Email support with 24-hour response + scheduled video calls for onboarding and troubleshooting
Q: Can multiple people share one account?
