“economic” vs. “economical”
Use "economic" for anything about the economy, economics, or policy at a systemic scale; use "economical" for anything about an individual choice being thrifty or cost-efficient.
economic
"Economic" is an adjective that relates to the economy, to economics as a field, or to money and resources on a systemic scale: economic policy, economic growth, an economic downturn. It describes something that pertains to the production, distribution, and management of wealth in a society, not whether a specific choice saves money for one person. "Economic" traces to Greek "oikonomikos," from "oikonomia" — household management, built from "oikos" (house) plus "nomos" (managing, law) — the same root that eventually gave English "economy" itself, originally about running a household efficiently before the sense broadened to national and global systems.
economical
"Economical" is an adjective that describes something as thrifty, cost-efficient, or sparing in the use of resources: an economical car, an economical use of ingredients, a person being economical with their time. It's a judgment about efficiency or frugality at the level of an individual choice, purchase, or habit, not about the economy as a system. "Economical" is built on the same Greek root as "economic" but took its own path through Latin "oeconomicus" and then acquired the English suffix "-al" specifically to carve out this narrower, personal-thrift sense, a split that had solidified by the 18th century as economics grew into its own formal discipline requiring a word untangled from household frugality.
The real distinction
The cleanest test is scale: "economic" describes systems, policy, and the discipline of economics, while "economical" describes individual efficiency or frugality. "The economic impact of the factory closing" is about the regional economy; "the economical choice was to repair rather than replace" is about one person's cost-saving decision. Writers most often slip by reaching for "economic" when they mean thrifty — writing "an economic car" when they mean a fuel-efficient, budget-friendly one — because "economic" is the more frequently encountered word in news and business writing and its extra familiarity makes it feel like the safer default even in sentences that are actually about personal frugality. There's a genuinely useful middle case worth knowing: "economics" as a field of study is always "economic," never "economical" (an economic theory, an economics degree), while nearly every phrase about saving money on a specific transaction wants "economical." One further wrinkle: British and American usage both preserve this distinction consistently, unlike some other -ic/-ical pairs (historic/historical, for instance) where the line has blurred over time; economic and economical have stayed cleanly separated in edited prose on both sides of the Atlantic, which is part of why the error, when it happens, reads as a clear slip rather than a permissible variant. Business writers should note that headlines about GDP, interest rates, or trade policy almost always want "economic," while product reviews and household-budgeting advice lean almost entirely on "economical" instead.

Memory trick
Think "economIC" for the big picture — policy, the economy, economICs as a discipline — and "economICAL" for a small, personal savings decision, since the longer word matches the narrower, more personal use. If the sentence could be rewritten with "thrifty" or "cost-saving" without changing the meaning, you want "economical"; if it's really about GDP, markets, or economics as a subject, you want "economic."
