Kalqer Launches Free Marketing Calculators for E-commerce & Digital Marketers

BRATISLAVA, Slovakia - Jan. 4, 2026 - PRLog -- Kalqer.com today announces the official launch of its comprehensive suite of free marketing calculators designed to eliminate spreadsheet complexity and democratize access to professional analytics tools for small businesses, freelancers, and marketers.

The Problem: Marketing by Guesswork

Over 60% of small businesses in Slovakia and Czech Republic lack visibility into whether their Google Ads and Meta campaigns are profitable. Expensive SaaS platforms cost hundreds of euros monthly, while manual Excel calculations consume hours and increase error risk. Kalqer.com bridges this gap with instant, accurate calculations requiring zero technical expertise.

• CPC/CPM/CTR Converter: Quantifies media buying efficiency between cost-per-click and cost-per-mille models, enabling optimal channel allocation across display, social, and search campaigns​
• PNO (Cost of Sale) Calculator: Measures advertising expenditure as percentage of attributed revenue—the definitive KPI for e-commerce campaign profitability and scaling decisions​
• ROAS Calculator: Calculates return on ad spend with industry benchmark comparison, isolating true incremental revenue from organic baseline performance​
• CLV & Payback Period: Models customer lifetime value against acquisition costs, projecting unit economics and capital recovery timelines for sustainable growth​
• Discount & Margin Calculator: Pre-launch scenario modeling for promotional strategies, calculating margin erosion and break-even volumes to prevent loss-making sales​
