I used to manually move money into savings, taxes, and a “fun fund” every time I got paid. I forgot at least once a month. Here’s the setup that fixed it in an afternoon.
The rule, in plain terms
- Every deposit over $200 into my business checking account triggers a split transfer
- 15% goes to a tax savings account automatically
- 10% goes to an emergency fund account automatically
- The rest stays in checking for expenses and pay
Most banks with sub-accounts or “vaults” support a rule like this. If yours doesn’t, a scheduled transfer on a fixed day of the month is a rougher but workable substitute.
The math behind the split
tax_savings = deposit * 0.15
emergency_fund = deposit * 0.10
available = deposit - tax_savings - emergency_fund
It’s not clever. That’s the point — boring and automatic beats clever and manual every single time money is involved.
