Every field explained. All abbreviations decoded. How to read the output.
How the Calculator Works
Sliders use a 0–10 scale. The model converts internally to 0–1. All historical fields (CPM, CTR, CVR, CPL) are optional — leave at 0 if you have no past campaign data. Providing even one real value raises confidence significantly.
Step 1 — Market
Where your ads will run and how competitive that market is.
Auto-fills all 4 market scores + CPM benchmark when selected.
Set automatically by country. Tier 1 = US/UK/AU/CA/SG. Tier 2 = BR/MX/SA/MY. Tier 3 = IN/BD/PK/NG/ID/PH.
How advanced digital commerce is in this country. US = 9.2 · India = 5.5 · Bangladesh = 4.2.
How widely consumers shop online and use digital payments. Higher = more online buyers.
Advertiser competition in Meta's ad auction. Higher = more bidding = higher CPM. US = 8.2 · Nigeria = 2.6.
Average consumer disposable income. Affects how much people spend when they convert.
Step 2 — Business
Your product or service type and how it affects ad spend behaviour.
Auto-fills business model, trust score, LTV score, and high-ticket toggle.
How you monetise. See business model glossary below.
Yes if your product/service costs above ~$500. High-ticket raises required spend because more touchpoints are needed to convert.
How much buyer trust matters before purchase. Finance = 9.0 · Real Estate = 8.8 · Ecommerce = 5.5. Higher trust need → higher CPL.
Relative strength of customer lifetime value. High LTV justifies spending more to acquire each customer. Real Estate = 9.2 · Restaurants = 4.5.
Business Model Options
Step 3 — Audience
Who you are targeting and how warm or cold they are.
Targeting method. Warmer audiences convert cheaper. See audience type glossary below.
Low = fresh audience. Medium = some repeat exposure (default). High = fatigued, rising CPL.
Total people in your target audience. Use the number from Meta Ads Manager audience size estimate. Don't inflate — overstating size inflates spend prediction.
Yes if you have a Meta Pixel with 1,000+ events or an uploaded Customer List. Enables cheaper retargeting layer, lowers overall CPL.
Audience Type Options
Step 4 — Creative
Your ad content quality and where it sends people.
Format of your ad. See creative type glossary below.
Where and how you convert the click. See funnel type glossary below.
Overall production and messaging quality. Blurry phone video = 3. Professional brand video = 8.
How compelling the first 3 seconds are at stopping the scroll. Generic opener = 4. Surprising/specific/pattern-interrupt = 8.
Yes if creative looks like organic social content filmed by a customer (not polished studio ads). UGC reduces CPL ~10%.
Steps between ad click and conversion. Single-page checkout = 2. Multi-step application = 7. Higher = more drop-off = more spend needed.
How well your landing page converts visitors. Mismatched copy, slow load = 3. Fast, mobile-optimised, with social proof = 8.
How hard it is to complete the goal action. One-click checkout = 2. Long form + phone verification = 8.

Step 5 — Economics
Your product value and historical ad performance data.
Listed price of your core product or service in USD.
Average amount per transaction, including upsells or bundles. If unsure, use same as product price.
Total revenue from one customer over their lifetime. Subscriptions: monthly revenue × avg months retained. One-time products: same as AOV.
Short = days (impulse, ecomm). Medium = weeks (courses, SaaS). Long = months (B2B, real estate).
How well-known you are to your target audience. Low = unknown. Medium = some recognition. High = established brand.
Your actual average cost per 1,000 impressions from past campaigns. Leave at 0 if no data.
Your actual average click-through rate. Enter as percentage: type 1.5 for 1.5%. Leave at 0 if no data.
Your actual conversion rate post-click. Enter as percentage: type 3.2 for 3.2%. Leave at 0 if no data.
Your actual cost per lead or purchase from past campaigns. Single most impactful field — even one real CPL value significantly raises accuracy.
Historical Data Impact on Confidence
Tip: Historical CPL is the single most impactful field. Even one real cost-per-lead value from a past campaign significantly improves accuracy.

Score Scale Reference (0–10)
All score fields (market maturity, creative quality, hook strength, etc.) use this same scale.

Common Mistakes
Drops confidence from High (84%) to Low (38%) and widens the range significantly. Even one real CPL value from a past campaign changes the output.
If you enter 10M for a niche product, the model assumes you can reach all 10M. Use the actual audience size number from Meta Ads Manager.
CTR = clicks ÷ impressions. CVR = conversions ÷ clicks. Both are entered as percentages — type 1.5 not 0.015.
For subscriptions or repeat-purchase products, LTV is typically 3–10× the product price. Underestimating LTV underestimates how much it's rational to spend on acquisition.
Score 10 means nearly impossible to convert. Only use 8+ if your funnel has 5+ steps, multi-stage payments, or requires document uploads.
Reading the Results
The model's central estimate. This is what a campaign with your exact parameters typically costs per month.
Minimum viable spend — the lower bound where results are still achievable. Good starting point if testing a new market.
Upper bound — maximum rational spend before diminishing returns dominate. Appropriate when scaling a proven campaign.
How well the model fits training data. 90.3% means it explains 90.3% of spend variance across 12,000 campaigns.
Based on how much historical data you provided. Low = 38% (benchmarks only) · Medium = 62% · High = 84% (your real numbers).
Mean Absolute Error — the model's typical miss distance. $24,200 MAE means predictions are on average within $24K of actual spend.
