Free calculators for people who buy leads
Your form builder reports how many people submitted. These work out what those submissions cost, what they were worth, and whether the difference you are looking at is real. Everything runs in your browser — no signup, no email, nothing sent anywhere.
What it costs
Money already spent, counted properly.
Form spam cost calculator
What are junk form submissions actually costing me?
Separates your reported cost per lead from your cost per lead a rep can actually work.
Open the calculatorCost per closed deal calculator
My cost per lead is lower. Is the campaign actually cheaper?
Shows the rank flip between the two metrics explicitly, rather than one at a time.
Open the calculatorCost per usable response
What am I really paying per lead I can sell to?
Prices the allowance against the junk rate, so you can see the share of the bill spent on submissions nobody can sell to.
Open the calculatorLead reconciliation
How many of my reported conversions were real people?
Prints the overstatement ratio — reported conversions per real prospect — and refuses to compute stages that cannot reconcile.

What it's worth
A change you are considering, priced before you make it.
Form field payback calculator
What does one more field cost me, and what would it have to be worth?
Solves for the required lift rather than asserting a drop, because nobody in this category has data on what a field costs.
Open the calculatorForm drop-off calculator
Which step of my multi-step form is losing people?
Prices the worst step against the median of the others, so the fix has a number attached rather than a feeling.
Open the calculator
What to believe
Whether the number in front of you is strong enough to act on.
Outcome-weighted split test calculator
Variant B converts better. Do I have enough closed deals to believe it?
Runs the significance test on closed deals as well as completions, and reports when the two metrics pick different winners.
Open the calculatorTime-to-outcome checker
Is my sales cycle fast enough for form-level outcome testing to work at all?
Adds the disposition lag to the accumulation time, and tells a large share of visitors that this method will not work for them.

Why eight, and not two hundred
There is an obvious version of this page with two hundred calculators on it, generated from a template, one per keyword. We are not going to build that, and the reason is not taste.
The rule we hold ourselves to is that a page ships only if it is useful when it does not rank. A calculator passes that test — it is still the thing you drop into a reply, still the thing you open on a call, whether or not anyone ever searched for it. A page that only pays off if Google sends traffic is a page we have no business making.
So each of these is a real modelling job rather than a swapped noun, each shows its own arithmetic, and each one says what it cannot tell you. If we ever get to two hundred, something has gone wrong.
About the numbers in them
Every calculator ships with defaults so it is useful before you touch it. Those defaults are examples, not benchmarks. Where a default stands in for something nobody has published data on — your junk rate, what a form field costs in completion — the page says so on the field itself rather than quietly implying we measured it.
We do not ship competitors’ prices inside these tools either. Third-party pricing claims about this category are frequently wrong; we found two widely repeated figures that contradict the vendor’s own live pricing page. You enter the numbers from the page you are looking at, and they stay in your browser.
The argument behind all of this is written out in full at the dishonest dashboard, including the best cases against it.
These are the numbers a form builder should have been giving you.
Endpoint Forms is an open-source form builder for marketers — built to convert, piping data wherever you need it, and carrying what each submission turned out to be worth back to the form that captured it. Pre-launch, built in the open.
