Embed our calculators on your site

Every CheckMyRaise calculator is free to embed on your own site — no account, no API key, no tracking pixel. Pick a calculator, copy the code, paste it into your page. That is the whole process.

The widget loads in an iframe from checkmyraise.com, so it stays up to date automatically: when we fix a rounding edge case or add a field, your embed gets it without you touching anything.

Paste this where you want the calculator

<iframe src="https://checkmyraise.com/embed/salary-increase-calculator/" title="Salary Increase Calculator" width="100%" height="760" style="border:0;width:100%;max-width:100%;overflow:hidden" loading="lazy" scrolling="no"></iframe>
<p style="font:14px/1.5 system-ui,sans-serif;margin:.5rem 0 0"><a href="https://checkmyraise.com/">Salary Increase Calculator</a> by CheckMyRaise</p>
<script>window.addEventListener("message",function(e){if(e.origin!=="https://checkmyraise.com"||!e.data||e.data.cmrEmbed!=="resize")return;var f=document.getElementsByTagName("iframe");for(var i=0;i<f.length;i++){if(f[i].contentWindow===e.source){f[i].style.height=e.data.height+"px";}}});</script>

Please keep the credit line below the calculator — it is the only thing we ask in return, and it is what makes the widget free.

How to install it

WordPress — add a Custom HTML block and paste the code. Do not use a Paragraph block; it will escape the tags.

Squarespace — add an Embed block, choose the code option, and paste.

Webflow — drag in an Embed element and paste.

Ghost, Notion, or plain HTML — paste it straight into an HTML card or your template.

If your CMS strips <script> tags from post content, untick “Auto-fit height” in the builder above and set a fixed starting height instead. The calculator still works; it just will not resize itself.

What we ask in return

Keep the credit line that sits underneath the calculator. That link is the only payment we take for the widget, and removing it is the one thing that would make us stop offering it free.

You are welcome to put your own heading above the widget, wrap it in your own layout, or place it anywhere on the page. You may not modify the calculation itself or present it as your own tool.

What the widget does and does not do

Every calculation runs in the visitor’s own browser. Nothing your readers type is sent to us, stored, or logged — there is no analytics call tied to their inputs and no cookie set inside the frame. That is the same privacy posture as the calculators on this site, and it is why the widget is safe to put in front of an audience discussing their own pay.

The calculators use the figures a visitor enters. They are not payroll software and they do not model tax brackets, filing status, or local deductions, so the after-deduction line is an estimate based on the percentage the visitor supplies. See our methodology for exactly how each number is worked out.

Which calculator should you embed?

Match the tool to what your page is about. A post about negotiating a raise pairs with the Salary Increase Calculator. A piece comparing two job offers wants the Job Offer Comparison Calculator. An article about inflation eating pay rises wants the Cost of Living Raise Calculator. An hourly-vs-salaried explainer wants one of the two converters.
