Buffer vs CPM Calculator: the short verdict

At a glance
Plan and publish social media content in one place
Buffer lets creators and small teams schedule social posts, analyse performance, and manage engagement across every major social network from a single dashboard - and has spent over a decade being the least complicated way to do that. The core loop is a queue. You set a posting schedule per channel once, then add content to the queue and Buffer publishes it at the next available slot, which removes the daily decision of when to post. Around that sit an analytics view for what actually performed, an engagement inbox for replies and comments, a landing-page builder for the single link in a bio, and an AI assistant for repurposing a post across formats. It is deliberately less than a full marketing suite, and that is the point. Buffer is also unusual as a company. It has published its salaries, revenue, and equity terms openly for years, operates fully remotely, and bought out its investors to stay independent rather than pursue an exit - which is why it is often cited as the reference case for a sustainable, transparent, bootstrapped-in-spirit SaaS business. For founders studying business models rather than shopping for a tool, that history is the more interesting part of the listing. Pricing is freemium: a free plan covers a small number of connected channels with basic scheduling, and paid plans are charged per channel, which keeps the entry cost low for a solo creator and scales predictably for a small team. There is no per-seat cliff of the kind that makes enterprise social tools expensive to adopt. The comparison depends on who is posting. Hootsuite and Sprout Social are built for marketing teams that need approval workflows, social listening, and reporting for a client or a board, and both cost considerably more. Later is stronger for visual-first Instagram and TikTok planning. Publer and Postiz compete directly on price, and Postiz is open-source for teams that want to self-host. Against all of them, Buffer's argument is time-to-first-post: it is the tool you can connect and schedule from in ten minutes, and the one least likely to be abandoned because nobody had the patience to configure it. It is the right choice for solo founders, creators, and small teams for whom social is one job among many. It is the wrong choice for an agency managing many client accounts with approval chains, or for a team whose main need is listening and sentiment analysis rather than publishing.
Free advertising calculators for CPM, spend, impressions, CPC, CTR, and eCPM.
CPM Calculator is a free browser-based toolkit designed for advertisers, marketers, publishers, media buyers, freelancers, and small businesses that need to plan and evaluate digital advertising campaigns. The main calculator lets users enter any two values among CPM, total ad spend, and impressions, then instantly calculates the missing value. This makes it easy to estimate campaign costs, compare media plans, and check whether a proposal fits an available budget. The website also includes focused calculators for CPC, CTR, eCPM, break-even ROAS, campaign reach, campaign comparison, and YouTube earnings. Each calculator explains the formula, shows the result immediately, and keeps the workflow simple for users who do not want to build spreadsheets or search for formulas. The tools are useful for planning new campaigns, reviewing past performance, comparing advertising channels, and communicating estimates with clients or teammates. CPM Calculator works directly in the browser and does not require an account, installation, or subscription. Users can select a currency label, enter their campaign data, and receive results without hidden currency conversions or unnecessary steps. The responsive interface works on both desktop and mobile devices. Unlike a large advertising platform, CPM Calculator is independent of any particular advertising network. It focuses on transparent calculations and practical planning tools that can be used across display advertising, social media campaigns, video advertising, publisher inventory, and other paid media channels.
