Next time you get paid

Will you remember this split? Will you actually move the money? Most people do the math once and never follow through.

Wealthsplitter makes it a four-minute payday routine that gets you ahead: investments, emergency fund, and savings goals get their share every time money lands. Enter the amount, get a checklist of exactly how much to move into each of your accounts, and make the transfers at your bank.

No budgeting, no expense tracking, no bank connection.

I built this for myself. I've been using it for over two years.

What is the 50/40/10 rule?

The 50/40/10 budget is a percentage-based approach to managing your money.

It divides your after-tax income into three categories:

  • 50% for needs: Essential expenses.
  • 40% for wants: Discretionary spending.
  • 10% for savings: Emergency fund, investments.

It's a starting point. Adjust the percentages to fit your situation. The important thing is having a routine.

Frequently asked questions

What if my income changes month to month?

The 50/40/10 rule works especially well when your pay changes: overtime, shifts, commission, or client work. You just apply the percentages to whatever landed. If you get $3,000 one payday and $7,000 the next, the split adjusts automatically.

Is the 50/40/10 rule right for everyone?

It's a starting point, not a rigid formula. If you live in an expensive city, you might need different percentages. Adjust them to fit your life. The key is having a routine you actually stick to.

Should I use the 50/40/10 rule for gross or net income?

Use your after-tax (net) income: the amount that actually hits your bank account. If you split your gross income, you'll overestimate what you have to work with.

What if I can't hit these percentages?

That's normal, especially if you're in a high cost-of-living area. The percentages are a starting point, not a pass/fail test. Start where you are, and raise your savings once the habit sticks. Even a rough split is better than no routine at all.
