Deal Gauge tells you when to walk away

Use the calculator on listings you find online to learn what fair looks like, before you ever spend a dollar.

Frequently Asked Questions
I've never bought gold before. Is Nu Stack the right place to start?
Yes. The free calculator and deal gauge are exactly what beginners need to evaluate a first purchase. Add the 2-week Pro trial and you also get the Chrome extension deal scanner and AI coin ID for the same price: nothing.
Do I need to know spot prices and karats to use it?
No. Nu Stack pulls live spot automatically and remembers every karat. You enter weight and pick a karat from a dropdown — that's it.
What's a 'good deal' on gold?
Generally, anything well below melt value is a strong deal. Nu Stack's Deal Gauge does this comparison automatically and color-codes the result so you don't have to do the math in your head.
