70 20 10 rule: a percentage budget with dates attached
The 70/20/10 rule is the simplest percentage budget: 70% of take-home pay for living costs, 20% for savings and investments, 10% for debt and giving. Its weakness is the same as every percentage system — it plans the month, not the days. On a dated calendar, the percentages land where the money actually moves.
- Three simple buckets
70% living, 20% savings, 10% debt — a split anyone can remember.
- Buckets with dates
See when each bucket is funded across the month, not just at month end.
- Transfers repeat monthly
Set the savings transfer once and it moves automatically every payday.
- Spot the short bucket
The projection shows which percentage is running short before the month ends.
How the 70/20/10 rule works
On payday you divide take-home income: 70% covers housing, groceries, transport and discretionary spending; 20% goes to savings and investments; 10% to debt payments and giving. It is more forgiving than zero-based budgeting and harder to forget than a detailed plan.
The calendar version adds one question: does the money arrive before the bills? If your 70% bucket is funded on the 25th but rent is due the 1st, the plan needs a timing fix — exactly what a dated view exposes.
Automate the split
- Set payday as a recurring income item.
- Create recurring transfers: 20% to savings on payday, 10% to debt.
- Let the running balance show what remains in the living bucket.
