These Come With Private Label Rights
You're not just getting tools to use — you're getting tools you can profit from. Here's exactly what you can do with them.
Sell Them at Any Price
Package these calculators as a product and sell them for whatever you like — $7, $27, $97, or more. You keep 100% of every sale. No royalties, no permission needed.
Give Away to Build Your List
Use them exactly like this — as a free opt-in gift that grows your email list with engaged, motivated subscribers who love practical tools.
Rebrand as Your Own
Swap in your logo, your colors, your name. Change the title, the footer, the fonts. Make them look 100% like your product — because with PLR, they are.
Bundle & Package Freely
Add them to a course, a membership, a coaching program, or a product bundle. Mix and match however you like — no restrictions.
Put Them on Any Website
Host them on your site as free tools to drive SEO traffic and keep visitors coming back — or gate them behind a login for your paid members.
Edit the Content Freely
Change any text, add your own tips, update the disclaimer, tweak the copy — the source code is fully open and editable in any text editor.
🌟
The only thing you can't do?
Pass on the PLR rights to your customers. You can sell or give the calculators themselves — just not the right to resell them with PLR. That's it. Everything else? Fair game.
