What You'll Learn

A hands-on, 7-day email course that walks you through every aspect of your finances. Each day you'll use a different NexTool calculator to assess, plan, and optimize one area of your financial life — from budgeting and debt to investments and retirement. By the end, you'll have a complete action plan.

Day 1: Budget Reality Check

Use the Budget Calculator to map your income vs. expenses. Identify your top 3 spending leaks and set a realistic monthly budget you can actually stick to.

Enter all your debts into the Debt Payoff Calculator. Compare Avalanche vs. Snowball strategies and see your exact debt-free date.

Day 3: Savings Acceleration

Use the Savings Goal Calculator to set an emergency fund target. Calculate exactly how much to save each month and when you'll hit your goal.

Day 4: Investment Health Check
