About This Site
About FreemarketingCalculator.com
Free, instant marketing calculators built for practitioners — no signup, no paywalls, no fluff.
What This Site Does
FreemarketingCalculator.com is a free collection of marketing calculators covering ROI, budget planning, conversion rates, email performance, salary benchmarks, agency valuation, and campaign metrics. Every calculator gives instant results with no account required, no email gate, and no hidden costs.
The site exists because most free marketing calculators are either buried inside expensive software, gated behind lead-capture forms, or simply broken. These tools are built to work the first time, every time, on any device.
Who Built This
FreemarketingCalculator.com is operated by Waseem Shahzad, a digital marketing professional with experience across SEO, paid media, and marketing analytics. The calculators are built using industry-standard formulas sourced from Gartner, HubSpot, Salesforce, Litmus, and other publicly available marketing research.
Our Methodology
Every calculator on this site uses formulas that are either industry-standard definitions (such as ROMI = (Revenue − Cost) ÷ Cost × 100) or benchmarks compiled from named public data sources. Benchmark tables are updated quarterly and show their last update date. No data is fabricated or estimated without a stated source.
Where benchmarks represent industry medians, this is stated clearly. Individual results vary based on audience, offer, and execution — the calculators are planning tools, not guarantees.
