Four free calculators for anyone running a busy Facebook or Instagram page. No signup, no email, nothing stored — every number is worked out in your own browser. Use them to put a figure on what your comment section is doing to your revenue, your team’s time and your ad budget.

Why we built these
Comment moderation is almost never measured, so it is almost never funded. It hides inside somebody’s job description, grows every time an ad does well, and only becomes visible when a scam account impersonates your brand under your best-performing post. Numbers change that conversation faster than arguments do.
Each tool takes inputs you can check yourself rather than industry benchmarks you cannot verify. Where a figure genuinely cannot be known — such as the performance drag from a hostile comment section — you set the assumption and the tool does the arithmetic. That is deliberate. A calculator that invents its own damage rate is a sales pitch pretending to be a measurement.
Nothing leaves your browser
These run entirely as JavaScript on the page you are reading. No inputs are transmitted, logged or stored, there is no account to create, and closing the tab discards everything. You can use them on real commercial figures without them going anywhere.
Frequently asked questions
Are these tools really free?
Yes, with no signup and no email capture. They exist because most page owners have never put a number on their comment section, and that number tends to speak for itself.
Do they work for Instagram and WhatsApp too?
The arithmetic is the same for any channel where comments or messages arrive faster than a human can watch them. The revenue and response-time tools apply directly to Instagram; the ad waste tool covers both Facebook and Instagram placements.
Which one should I start with?
The Response Time Grader, because it needs the fewest inputs and usually produces the biggest surprise. Once you can see your real wait including overnight comments, the other three explain what that wait is costing.
Can I use these figures in a proposal or budget request?
That is what they are for. State your inputs alongside the output so the reader can challenge the assumptions rather than the arithmetic — a moderation budget is far easier to approve when the workings are visible.
