Ad spend forecast FAQs
Forecast accuracy depends on input quality. With stable CPC and conversion rates, forecasts are typically within 10-15% of actuals. Seasonality and auction dynamics introduce variance. Our tool includes seasonality multipliers to improve Q4 accuracy. Track actual vs forecast monthly to refine assumptions.
Daily budget × 30.4 = monthly spend (accounting for varying month lengths). Google Ads and Meta use daily budgets but pace spend across the month. Our calculator handles both—enter daily to see monthly, or enter monthly to calculate required daily budget.
Apply seasonality multipliers. Example: November/December often have 1.5-2x higher CPCs due to competition. Use our seasonality tool to adjust forecasts by month. Black Friday week may require 3-4x normal daily budget to maintain impression share.
Averages by industry: Legal ($6-10), Insurance ($4-8), Real Estate ($2-5), Ecommerce ($0.80-1.50), B2B SaaS ($3-6), Local Services ($2-4). Our calculator lets you input your specific CPC for accurate forecasts.
Conversions = Clicks × Conversion Rate. Forecast clicks = Daily Budget ÷ CPC × Days. Example: $100 daily budget, $1 CPC = 100 clicks/day. 3% conversion rate = 3 conversions/day, 90/month. Our goal-based budgeting reverses this—enter target conversions, get required budget.
1) Use 30-90 days of historical data for CPC and conversion rates. 2) Separate forecasts by campaign type (brand vs non-brand). 3) Apply device multipliers (mobile often cheaper). 4) Adjust for seasonality. 5) Review actual vs forecast monthly and refine assumptions.
