Don’t Just Calculate. Test the Decision.
Free simulators and calculators that show what a decision actually costs, earns or saves — using transparent, source-verified assumptions.

Know What You Actually Keep
A $1,000 sale isn’t necessarily $1,000 of income. Run your own numbers before pricing, selling or launching.
What actually lands in your account from a $1,000 customer payment
Platform fees, payment processing, marketplace costs and acquisition expenses can all change the result. UIG’s tools let you model those variables before you price, sell or launch — not just read a static answer.
