Ad spend and marketing budget are related, but they are not always the same number.
Ad spend usually means media spend: the amount paid to ad platforms, networks, or placements. It is the money used to buy clicks, impressions, video views, conversions, or other paid distribution.
Marketing budget is often broader. It can include ad spend, creative production, landing page tools, email software, agencies, freelancers, analytics tools, promotions, and internal marketing costs.
The difference matters because metrics can change depending on which cost number you use. ROAS often uses ad spend. ROI and CAC may use broader marketing cost. MER can be calculated with total marketing spend when you want a blended view.
Use the Ad Spend Calculator at /tools/ad-spend-calculator when planning paid media budget from a revenue target. Use CAC, ROI, MER, and payback period tools when you want to include broader marketing cost and business impact.
