Word for calculating/adjusting a payment when I previously paid too much?

As part of a percentage rent, I need to pay my landlord 10% of my monthly revenue, but no lower than \$10,000.

Therefore, I automatically pay \$10,000 at the beginning of each month. So let's say we're dealing with January. I pay \$10,000, and shortly into February, I have determined my monthly revenue, and 10% of it is \$15,000. Now I need to pay an additional \$5,000 for January, instead of all 10% of my revenue (because I already put down \$10,000).

Now, what is the word for what we did to the 10% of revenue to use only the portion needed to leave the landlord with only \$15,000?

Example sentence:

Because I have already paid \$10,000, we must _________ the \$15,000.

The word offset has been suggested, but I do not think it is an accurate choice.

Also - please make suggestions that fit in the example sentence above, the structure is quite important to my question.

• "For January's rent we owe \$15,000, less the \$10,000 we have already paid." Feb 1, 2017 at 15:23
• Because I have already paid \$10,000, we must pay the difference to make up the \$15,000. Feb 1, 2017 at 20:05
• Because I have already paid \$10,000, we must pay the residual of \$5000 on the total of \$15,000. Feb 7, 2017 at 16:12
• please make suggestions that fit in the example sentence above, the structure is quite important to my question. This is a great example of someone trying to fit a square peg in a round hole.

You deduct the advance payment (\$10,000 in this case) from the final/total rent payable.

Because I have already paid \$10,000, we must deduct it from the total (\$15,000).

ODO:

deduct VERB

[WITH OBJECT] Subtract or take away (an amount or part) from a total:
‘tax has been deducted from the payments’

‘Any severance already paid to the workers will be deducted from that amount, the judge ruled.’

TFD(idioms):

deduct (something) from (something else)
to subtract an amount from another amount.
Mr. Wilson deducted the discount from the bill.

McGraw-Hill Dictionary of American Idioms and Phrasal Verbs. © 2002 by The McGraw-Hill Companies, Inc.

Wiktionary:

Verb deduct (third-person singular simple present deducts, present participle deducting, simple past and past participle deducted)
To take one thing from another; remove from; make smaller by some amount.
I will deduct the cost of the can of peas from the money I owe you.

... we must pay the balance.

Offset is fine, but you don't offset the \$15000. You offset the \$10k against that sum.

Because I have already paid \$10,000, we must offset it against the \$15,000.

Oxford's definition isn't particularly helpful, but there is an example which matches, noting how tax liability can be reduced by charitable donations already made:

offset verb
[with object] Counteract (something) by having an equal and opposite force or effect:

‘donations to charities can be offset against tax’

Other examples, showing a slightly different usage:

• The cost would be roughly \$1.5 billion, which he says would be offset with spending cuts. [online.wsj.com]
• The cost of the program was partly offset with a \$1 million grant from Mercury Insurance. [dailynews.com]

In both usages, offset against and offset with, the larger sum is as stated and the smaller sum is offset.

• It seems to me that was is being counteracted here is the \$15k - according the the rules, I need to pay the 10% which is 15,000. The \$10,000 I have already paid counteract that amount.

• As I said, the Oxford definition is not very helpful. Their example shows it in use, in a situation which is analogous to yours. A sum already paid is offset against a sum due. Feb 8, 2017 at 9:12
• Thanks for you answers. I find it hard to get a clear understanding by skipping the definition and using the example (i've seen this definition in other dictionaries also, and it really seems to be what I suggested), which is why I'm reluctant to award you the bounty. Can you back this up further?

• Alternatively, couldn't we offset the 15k with the 10k? See here for some examples: fraze.it/…

• You can use offset with, but it's still the smaller sum which is offset. Feb 12, 2017 at 10:06

The overage is exactly the term for the additional increment of rent that you must pay:

overage, 1: Rental increment tied to sales or profit that is in addition to the flat rental fee. Assume a retail store in a mall is charged a base rental of \$5,000 per month plus 2% of sales. If sales are \$100,000, the overage would be \$2,000 and total rental would be \$7,000.

So, for your hypothetical month of February, your overage is \$5,000, your total rental is \$15,000, from which you debit the \$10,000 base rental already paid.

To fit your sentence:

Because I have already paid \$10,000, we must debit it from the \$15,000.

To fit more common usage, the sentence should use the form be debited somehow:

Because I already paid my base rent, \$10,000 should be debited from this month's rent of \$15,000.

• It might well be, and it's not the point, Gnawme. That's not what was asked Feb 10, 2017 at 0:31
• @RobbieGoodwin If you read the entire answer, I filled in the blank of the sentence the OP wanted completed. Feb 10, 2017 at 5:45
• Thanks Gnawme and while that looks fine in ordinary English two things. 1) We're not talking about ordinary English, but a rather specialised vocabulary where a mistake could cost the poor guy a lot of money 2) You didn't fill in the sentence. You changed it for another, even though the poor guy had specifically stressed: 'Also - please make suggestions that fit in the example sentence above, the structure is quite important to my question.'

• This is a useful answer, thanks for the new word! However, it doesn't actually fit my needs.

• @RobbieGoodwin - I'm writing a user guide for a software that has this functionality, and trying to find the appropriate words to describe it, so don't worry, no one will lose a lot of money. I'll be sure to describe everything well enough that even if the terminology isn't perfect, people will understand what they're doing. P.S. I'm not a poor guy, really doing fine :)

"Because I have already paid \$10,000, we must now settle the arrearage of the \$15,000."

arrearage:

something that is in arrears; especially : something unpaid and overdue. (Merriam-Webster)

Because I have already paid \$10,000, we must remit the amount from the \$15,000.

https://www.vocabulary.com/dictionary/remit

"If you’ve been in prison for five years of a seven-year sentence but you’ve been on good behavior, a judge might remit the remainder of your sentence and let you go free."

"release from (claims, debts, or taxes) “The taxes were remitted” Type of: cancel, strike down declare null and void; make ineffective"

• This many downvotes with no explanation? Can someone enlighten me as to why the word is not appropriate for this post?
