Card checkout is not switched on yet — email us and we will set you up today
The subscription plumbing is built and tested, but we are still finalising the merchant account behind it, so there is no live checkout link on this page right now. In the meantime, email admin@markcolabs.com with the plan you want and we will set you up by hand at the same published price. Nothing about the plan or what it includes differs — only how the first payment is collected. The Free plan is unaffected and available right now.
Prices on this page are US dollar list prices, before tax. Where we are registered to collect sales tax, it is calculated and shown to you at checkout, so the figure you are charged may be higher than the figure on the card. Paid plans are available to customers in the United States only. Cancelling, renewals and refunds are covered by one refund and cancellation policy.

Frequently Asked Questions
How does embedding work?
Add a single script tag to your page. The script creates an iframe that loads the calculator widget. The iframe is sandboxed for security and auto-resizes to fit your container. No backend setup, no API keys, and no authentication required.
Can I customize the look and feel?
On the Pro and Enterprise plans, you can set your brand color and logo using data attributes on the script tag. Use our Brand Configurator to preview your brand applied to every widget in real time. For deeper customization, Enterprise customers can request custom CSS or widget layouts.
What calculators are available?
We currently offer 10 embeddable widgets: Mortgage Payment, Loan Payment, Tip Calculator, Compound Interest, 401(k) Retirement, Savings, Investment, IRA, Debt Snowball, and the Money Flow Visualizer. Enterprise customers can request additional calculators built to specification. Visit the Widget Gallery to preview all available widgets.
Will the widget slow down my site?
No. The embed script is only 2KB and loads asynchronously. The calculator runs inside an isolated iframe, so it does not affect your page's JavaScript, CSS, or Core Web Vitals scores.
Can I cancel anytime?
Yes on Pro. There are no long-term contracts for the Pro plan: cancelling stops the next renewal, Pro features continue to the end of the period you have already paid for, and you can stay on Free after that. White-Label is an annual term, so it runs to the end of the year you have paid for and renews only if you ask it to. Enterprise contracts are negotiated individually. The full terms are in our refund and cancellation policy.
Is there a free trial for Pro?
Yes. All new Pro accounts include a 30-day free trial. No credit card is required to start. You will only be charged if you choose to continue after the trial ends.
What happens when I reach the widget limit?
Free plan users are limited to 3 widget types. Upgrading to Pro unlocks all 10 current widgets and any new widgets added in the future. You will never lose access to widgets you are already using.
Do you offer refunds?
Not for the unused part of a billing period. Cancelling stops the next renewal, and you keep access to the end of the period you have already paid for. We do refund duplicate charges and charges made in error, and we give refunds where the law requires them. The Pro plan's 30-day free trial takes no card, so you can try it before you pay. The full terms are in our refund and cancellation policy; to ask about a charge, email admin@markcolabs.com.
