A calculator gives you numbers. A system tells you what to do next.

Most financial calculators answer one isolated question. This workshop connects allocation, cash flow, and purchase decisions into one evolving financial snapshot.

Step 1Build

Build your monthly money system.

Your paycheck should have assignments before spending begins. The simulator divides take-home income among an Income Account, Safety Account, and Wealth Account.

Why start with allocation?

A predetermined split makes savings and investing part of the system instead of depending on month-end leftovers.

Which split should you use?

The balanced 60/20/20 model is a starting point. Your expenses, reserves, and goals may justify another allocation.
