Costing is pronounced /ˈkɒstɪŋ/ in US and UK English, with primary stress on the first syllable. Start with the 'k' sound, open back rounded vowel /ɒ/ as in 'cot,' then the 'st' cluster, and finish with a short /ɪ/ followed by the nasal /ŋ/. In casual speech, you may hear a slightly reduced final vowel in rapid contexts, but the core is /ˈkɒstɪŋ/. You can practice by saying 'KOST-ing' clearly, ensuring the tongue sits flat for /ɒ/ and the lips are relaxed before the /t/ and /s/ sequence.
Common mistakes include pronouncing the first vowel as /ɪ/ (as in 'kit') instead of /ɒ/; and merging /t/ and /s/ too softly, turning /t/ into a flap or blending sounds. Another error is devoicing or de-emphasizing the final nasal /ŋ/. To correct: keep the /ɒ/ vowel open and back, articulate a clear /t/ before the /s/, and finish with a distinct /ŋ/ by pulling the tongue to the velum, allowing air to escape through the nose. Practice with the pair 'cost' and 'kossing' to feel the difference.
In US English, /ˈkɒstɪŋ/ typically uses the open back /ɒ/ as in 'cot,' with rhotics not affecting the word. UK English retains /ˈkɒstɪŋ/ with similar /ɒ/ but may exhibit stronger non-rhoticity overall; Australian English often shares /ˈkɒstɪŋ/ but can show slight vowel shortening and a less pronounced 'r' influence overall. The main distinction is vowel quality and flapping tendencies, which do not drastically change the core syllable but may influence perceived length and clarity.
The difficulty lies in the /ɒ/ vowel, which doesn’t exist in all dialects, and the /st/ cluster immediately before the /ɪ/ and final /ŋ/. A common trap is misplacing the tongue to produce a shorter /ɒ/ or producing a /t/ too softly so /st/ blends with the following consonants. Another challenge is sustaining the final /ŋ/ clearly in connected speech. Focus on a clean /st/ articulation and a separate, audible /ŋ/ at the end.
The word depends on a crisp /t/ before /ɪ/ and a distinct /ŋ/ at the end. A cost-aware nuance is avoiding lateralization of the /s/ into the /t/ and ensuring the vowel /ɒ/ doesn’t centralize into a schwa. In careful speech you’ll hear a short but clear /t/ before the /ɪ/. Practicing with minimal pairs like 'coast' vs 'cost' and adding the suffix '-ing' helps you maintain the syllabic rhythm and separate the consonant sounds.

Costing derives from cost, which originates from the Old French coutse or custoise, from Latin custus meaning 'expense' or 'to cost.' The noun cost emerged in Middle English under the influence of commercial and legal vocabulary. The verb costing developed as English speakers described the act of calculating or estimating costs, aligning with accounting and trade practices that intensified in the late medieval and early modern periods. Over time, the form costing became standardized in business parlance to denote the regular process of determining expenses for products, projects, and operations. The term solidified in technical contexts during the rise of double-entry bookkeeping and cost accounting in the 18th and 19th centuries, expanding into contemporary management accounting where costing is essential for pricing, budgeting, and competitiveness.
