Type how many people started the form and how many submitted it. The abandonment rate and the completion rate update as you type. The sample numbers are arithmetic only.
Form abandonment rate calculator

Abandonment rate: 36%. Completion rate: 64%.
Illustrative defaults (1,000 starts and 640 completions). Use your own numbers.
What this calculator measures
This calculator turns two counts into an abandonment rate and a completion rate. You type how many people started the form and how many submitted it. It does not read a live form. LeadFormHub does not store form starts, so a true abandonment rate needs a start count from another tool, paired with completions you can see.
Abandonment is the share of starters who leave before a successful submit. Completion is the share who finish. A page view is not a start. Someone who only sees the page and never focuses a field has not started, so submissions divided by views is a conversion rate, not an abandonment rate.
On Pro and Business, analytics show views, submissions, conversion rate (submissions divided by views), submissions over time, and top forms. Use that conversion rate when you have no start count. Use this calculator when you do have starts, and keep both counts on the same dates.
The formula
Form abandonment rate is one minus completions divided by starts, shown as a percentage. Completion rate is completions divided by starts. Completions cannot be higher than starts. If they are, the start definition is wrong or the two counts cover different dates. The calculator refuses that input instead of printing a negative rate.
Write it as abandonment rate = (1 − completions ÷ starts) × 100, and completion rate = (completions ÷ starts) × 100. The defaults, 1,000 starts and 640 completions, only show the arithmetic: 36 percent abandoned and 64 percent completed. They are not a target and not a typical rate.
How to read the result
Read the two rates together, then compare them with your own earlier window. A higher abandonment rate means more starters left. It does not say the form is bad, the traffic is bad, or that you should copy a number from another company. Change one thing, keep the offer as steady as you can, and compare the next equal window.
A short form can still lose people when the button is vague or an error does not say what to fix. A longer form can still finish well when every field is used on the first reply. Compare forms that share an offer. A quote form and a newsletter form are not the same job.
If you only have views and submissions, stay with conversion rate. Mixing that rate with abandonment in one chart hides whether people never started or started and quit.
Three steps to lower abandonment
Lower abandonment by removing a field you will not use on the first reply, putting the reason for a sensitive question in the label, and making the button name the result. Check the form on a phone before you send traffic. Add a verification step only when a bad contact is expensive enough to justify the extra tap.
Cut one unused field. If the first reply does not need company size, city, or a second contact method, take it off. Ask it on the call and store it in the lead note. Required fields should be the ones that block follow-up when they are empty.
Say why you ask. Phone is easier to accept when the label says it is for the callback. Budget is easier when the label says it keeps you from recommending the wrong package. Placeholder text is not a reliable place for that reason.
Make the finish obvious. Name the button for the outcome, such as Get a callback, and keep the form readable on a phone. SMS OTP supports India mobile numbers; email OTP works worldwide. OTP is not on the free plan. Pro includes 100 verifications a month and Business includes 1000.
Embed this calculator
Paste the snippet into a page you control. The iframe loads only this calculator, and the paragraph under it links back here. Keep that link. It credits LeadFormHub and sends readers to the formula, the reading guide, and the three steps on this page.
These answers cover the rate itself, how it differs from conversion, what LeadFormHub stores, and how the embed credit works. Use your own starts and completions, and keep both counts on the same dates. The sample figures on the calculator are not a benchmark to chase.
There is no universal good rate to copy. Compare this form with its own earlier result after one change. The sample numbers in the calculator are arithmetic, not a benchmark.
Abandonment uses starts and completions. Conversion rate in LeadFormHub is submissions divided by views. A view is not a start, so the two rates answer different questions.
No. Pro and Business analytics show views, submissions, and conversion rate. They do not record form starts or which field someone left on.
Yes. Copy the embed snippet and keep the “Free calculator by LeadFormHub” link under the iframe. That link is the credit.
