Put a concrete calculator on your website
One line of HTML puts any of these 10 calculators on your page. No account, no key, no invoice, and nothing tracking the people who use it.
- Free forever, on any number of pages
- No sign-up, no API key, no rate limit
- No cookies and no analytics on your visitors
- Lazy-loaded, so it costs nothing until it is scrolled to
- Fluid from about 300px wide — sidebar or full width
- Follows your reader's light or dark preference
The one condition, said plainly
Keep the credit line under the frame. That is the whole arrangement, and it is stated here rather than hidden in terms nobody reads: these calculators cost real work to build and they are given away because a link from a page like yours is worth more to us than a licence fee. If you strip it, the calculator still works and nothing phones home. We would just rather ask.
Pick a calculator
Each one has its own copy-paste snippet at the bottom of its page. Here is the slab calculator’s, which is the one most sites want — swap the slug for any of the others listed below it.

</script>Flatwork and slabs
Cubic yards, waste and how many ready-mix trucks — plus the short-load fee nobody warns you about.
Tons to order, loose against compacted, so you are not a fifth short with the plate on site.
Bar count, linear feet, ties and chairs — with the wire mesh alternative costed beside it.
Tons of debris and how many containers that really is — because a concrete box fills by weight long before it fills by volume.
Hardscape
Structural pours
Footing yardage rolled into the slab total, because you are ordering one truck.
Yards for a flight of cast steps — or the bag count, because a stoop is almost always a short load.
Concrete per pier and for the whole deck, with the footing bell and the frost line accounted for.
Grout for a CMU wall at your rebar spacing, with the bond beam counted — not the four-times-too-much rule of thumb.
Who these are for
Ready-mix and aggregate suppliers
A yardage calculator on your product page answers the question every caller opens with, and it keeps them on your site instead of sending them to a competitor's.
Building supply and rental
Base stone by the ton, rebar by the bar, block by the pallet. The calculator produces a materials list, which is a shopping list on your own site.
Trade blogs and associations
A working tool beside an article is the thing readers bookmark, and it is far cheaper to add than another thousand words nobody finishes.
Contractors with a website
Put the calculator you actually use on your own services page. It is a reason for a homeowner researching a driveway to stay on your site rather than on a national directory.
Questions
Can I put a concrete calculator on my website for free?
Yes. Every BidPour calculator can be embedded on any site at no cost, with no account, no API key and no registration. Copy one iframe tag into your page and it works. The only thing asked in return is that the credit link underneath the frame stays.
Does the embedded calculator track my visitors?
No. The embedded frame sets no cookies, runs no analytics and sends nothing about your visitors anywhere. It is the calculator and nothing else. It also loads lazily, so it costs nothing until somebody scrolls to it.
Will the calculator fit my page width?
It is fluid and works from about 300px upward, so it fits a sidebar or a full-width article. The snippet includes an optional three-line script that resizes the frame to the calculator's real height, so there is no inner scrollbar and no dead space.
Do I have to keep the credit link?
That is what is asked for in return, and it is stated plainly rather than buried in terms. A page that strips it still gets a working calculator — nothing breaks and nothing phones home. It is a request, made honestly, for something free.
And if you pour concrete yourself
The same calculators turn into a priced, branded quote your client accepts from their phone — no account to start, and your first one is free.
