The cost savings "are" or "is" 50%?



I wonder if I should use are or is in the following sentence:

The cost savings ____ 50%?

Or should I just say the cost savings percentage is 50%. Thanks

Is it from a test? Do you need to choose between two options, or are you free to fill in any word you would find appropriate? – CowperKettle – 2015-12-08T15:41:53.417

It's interesting why cost savings is is used. Could it be a tricky part of a larger phrase in some instances, like "The plan that you say will result in cost savings is a recipe for disaster". This would disqualify some of the ngram results. – CowperKettle – 2015-12-08T16:16:06.693

2@CopperKettle Cost savings is comes naturally to me. Perhaps this is a BrE/AmE distinction. There is only one set of savings, regardless of how many units of money it represents. – choster – 2015-12-08T16:28:38.423

@choster - I've run an ngram search for "the cost savings is", and it returned zero results... – CowperKettle – 2015-12-08T16:31:25.493


On closer examination, my NGram was misleading, and I wondered if I had just had a brain fart. But no, the savings is is definitely in use: The savings is the difference, The savings is equivalent to, The savings is immediate, The savings is not always substantial, etc.

There is a cost savings of 50%. Or: There is a 50% cost savings. Please note: there is no BrE/AmE issue here at all. The search term would be: a cost savings of [some amount]. – Lambie – 2019-08-26T22:44:55.467



“Are” is always used with plural words—savings are. “Is” is always used with singular words—saving is. In this case, I believe the trouble you’re having is not with are vs is but rather the word savings. The correct sentence would be: The cost saving (no s)is 50%.

I would say definitely don't rephrase to include the word "percentage". Bear in mind that "50%" is pronounced "fifty percent" - saying the saving percentage is fifty percent would sound incredibly awkward to any native speaker, and discarding the actual word "percent" wouldn't be much better (nor would it match the written form).

Idiomatically, the usual form is the cost savings are fifty percent, but there's nothing at all wrong with the cost saving is fifty percent - it's just less common, particularly in more recent decades.

Mixing a plural subject with a singular verb is rarely acceptable in English; this isn't one of the rare exceptions. As to whether the saving(s) should be singular or plural, I would say that if you're definitely referring to the cost of one single thing you can't use the plural form. In (almost?) all other contexts you can use either singular or plural.

I say "almost" because I can't think of a context where you can't use the singular form (it's probably always possible to conceptualize all costs or savings as one cost or one saving), but it's at least feasible someone can think of a context where only the plural form works.

Thanks. I checked but saving vs savings and majority will say people rarely use saving. Seems like there is no clear answer... too ab i have to use this phrase a lot as my work is requires me to – hj630 – 2015-12-09T16:03:23.093

@hj630: Per my final paragraph, unless anyone can think of a context where you can't use the singular form (I can't), the clear answer for anyone who's not sure is *Always use singular "saving"*. It's not really important that this happens to be the less common form, if the net result is that no-one would ever think you've made a "mistake". – FumbleFingers Reinstate Monica – 2015-12-10T13:13:41.987


@discodane is right. Saving is only used when it refer to one instance of reducing something. Remember when you put "ing" at the end of a verb, you change the verb into a noun. That's the only case where saving is used. See the following example:

You can enjoy a year's membership for just $28 – a saving of $7 off the regular rate.

In the case above, you can change saving to reduction or reducing.

As for the case where the word savings is used, bear in mind savings is a word/term, instead of the plural form of saving. So I believe the answer to your question should be

The cost savings is 50%.

"Is" is the correct answer. What you are referring to is a singular percentage of a singular cost. What the number is before the percentage is irrelevant. It is a singular percent so the cost savings IS 50%.

A counter example would be if there were multiple costs.

"The costs(plural) savings are 50%"
