Leave it empty if they have not named one
Buyers set their own and they move it: some work in the sixties, some above eighty, and the same buyer changes it between markets. This loads at a value because the field has to — put in what yours told you, or clear it to leave the profit line as the only test.

The deal survives your buyer's own test
Your buyer clears $67,430 — 20.8% of the after-repair value — and the tighter of their two tests, their 70%-of-ARV rule, still leaves $1,550 of room on the fee. Whether to take that room is a judgement about the relationship and the depth of your list, and this page has nothing to say about it.

How this is calculated
The whole page is one subtraction and that subtraction turned around.
buyer’s profit = ARV − (contract price + your fee) − repairs − carry − cost of selling
The bracketed term is what your buyer pays you. It is one number to them however the paperwork divides it, which is why the fee sits inside the purchase rather than beside it — the same reason the assignment-fee page takes the buyer’s all-in figure as its input.
Turned around, it gives the ceiling on the fee. Solve the same statement for the fee, holding the profit at whatever your buyer said they need:
max fee = ARV − repairs − carry − cost of selling − required profit − contract price
It is derived rather than searched for, so the two cannot drift by a rounding step: put that fee back into the first formula and the profit is exactly the required one.
The percentage rule is the second test, and it is your buyer’s. A buyer who works to a share of after-repair value is using a shorthand that already contains their carry, their cost of selling and their profit:
their ceiling = ARV × percentage − repairsmax fee under the rule = their ceiling − your contract price
That first line is the same functionthe investor suite’s maximum allowable offer calculator runs, called rather than copied. Two implementations of one formula agree until one of them is fixed.
There is no standard percentage and this page does not supply one. It is a property of the buyer rather than of the market: it moves with how fast houses are selling, with what the property needs, and with what the buyer intends to do with it. The field is editable, it loads at a value only because a numeric input has to, and nothing on this page describes any value as classic, typical or usual. Clear it and the profit line becomes the only test.
Whichever is tighter is the one that binds. The page reports both ceilings and names the smaller, because a buyer with two requirements is turned down by the first one you break. On a tie the profit build-up is named, since it is made of stated figures a reader can check line by line while the percentage is a convention.
The two supporting ratios are profit ÷ ARV and profit ÷ everything your buyer spends. Neither is a target and neither is compared to one here. No loan is modelled anywhere on this page, so a buyer using borrowed money has points and interest that are not in these figures.
Every figure that cannot be computed shows an em dash rather than a confident zero — with no after-repair value or no contract price there is no answer to give, and a zero would be a different and wrong claim.
Common questions
What percentage of ARV should I use?
This calculator will not tell you, and that is a decision rather than an oversight. The percentage is a shorthand that bundles a buyer's carry, their cost of selling and their profit into one number, so it is not a property of the market — it is a property of the buyer, and it moves. The same buyer runs a different number in a market where houses sit than in one where they do not, a different number on a house that needs a roof than on one that needs paint, and a different number again if they intend to rent it rather than sell it. Any figure this page offered would be wrong for somebody the first day it shipped, and it would be wrong in the direction of talking you into a price. The field loads at a value because a numeric input has to load at something; ask your buyer what theirs is and put that in, or clear it and let the profit line be the only test.
Why are there two ceilings on the fee, and which one is right?
Because buyers state their requirement in two different ways and neither implies the other. Some name a profit they must clear, which is an explicit figure you can check against the line items. Others name a percentage of after-repair value they will not go above, which is the same requirement compressed into one number along with their carry and their selling costs. A buyer who gives you both is usually giving you two different opinions formed at different times, and only the tighter one matters — that is the one this page calls the binding test. Which is tighter is an output, not an assumption, and on the figures as they load it is the percentage by a wide margin. If the two disagree materially it is worth asking your buyer which they actually apply, because the answer changes what you can ask for.
Is the profit figure here the profit my buyer will report?
No, and it is not trying to be. It is the profit implied by the numbers on this page — the after-repair value, the work, the carry and the cost of selling, all of them estimates entered by you. It assumes no loan, so a buyer using hard money will pay points and interest that are not here, and it assumes the work comes in at budget and the house sells at value, which are the two places a flip most often loses money. What it is good for is the conversation: it puts the same subtraction your buyer is doing on a screen you can both look at, itemised, so a disagreement is about a line rather than about a conclusion.
Why is the carry and the cost of selling included when my buyer never mentions them?
Because leaving them out is the single largest source of optimism in this arithmetic, and because your buyer is not leaving them out — they simply are not saying them to you. Several months of money, taxes, insurance and utilities, then a commission and their side of the second settlement, routinely come to a tenth of the after-repair value between them. A version of this sum done without those two lines makes a deal look like it clears far more than it does, and the person who finds out is you, in the form of a buyer who goes quiet after running their own numbers. Entering them is also what makes the fee ceiling on this page honest, because both of them come out before the profit does.
Does this agree with the maximum allowable offer calculator?
Exactly, and by construction rather than by coincidence. The investor suite's maximum allowable offer answers the opposite question — the most a buyer can pay, given a percentage, a repair budget and a fee — and this page reuses that same function rather than writing the subtraction a second time. Feed the fee ceiling from here back into that page with the same after-repair value, percentage and repair budget and it returns your contract price precisely. Two implementations of one formula would agree until one of them was corrected, which is the failure the shared arithmetic module exists to remove; there is an assertion that pins the round trip.
What does a negative fee ceiling mean?
That the contract price on its own already breaks whichever test is binding, so there is no fee — not even a fee of nothing — that makes the deal work for that buyer on those numbers. It is deliberately shown as a negative rather than floored at zero, because a floor would turn a deal that cannot be done into an instruction to work for free. The useful reading is the size of the negative: it is how far the contract price would have to come down before there is anything to charge for. That is a renegotiation, a different buyer with a different requirement, or a different property.
