What is the past tense & past participle of "cost"? Is it correct to say the following? Hi friends, My question is on the usage of "cost". What is the past tense and past participle of "cost"? Is it correct to say the following? 1) So far, it has costed me 10,000 dollars. 2) We built this small shed yesterday. It costed me only 2,000 pounds. 3) It has been costing me 7000 dollars since January 2018. Thanks in advance! Niwantha

In the most common case, the past and part participle of "cost" are both simply "cost." "Today, it costs $189.95. Yesterday, it cost $269.95. If it had cost $189.95 yesterday, I would have bought it yesterday. Perhaps it will cost even less on Black Friday." Your third example is interesting. The grammar is correct, but there is a logical problem in the real world. The grammar expresses a continuing or progressive action in the past so it is not logically correct. Suppose it has cost you $1,000 each month (end of January to end of August, perhaps), and the total cost has now added up to a total of $7,000. Your grammar is correct for the continuing, recurring monthly cost, but you would need to say "$1,000 per month." Thus, these two sentences are both grammatically and logically correct: "It has been costing me $1,000 per month since January." "It has cost me $7,000 since January." There is a rarer form of the verb "to cost" that is used only in business situations. It means "to determine the cost of." In this case the part participle is "costed." "We are having this problem because we failed to cost the shipping charges realistically. If we had costed them properly, we would have realized that we needed to price the contract higher. In future, we will cost them more conservatively and include seasonal adjustments."
