💡 Quick Answer:
The 50-30-20 rule is a simple budgeting method where you divide your income into three parts:
- 50% for Needs (essential expenses)

- 20% for Savings and Investments
This rule helps you control spending, build savings, and avoid debt.
Imagine This

| Category | Percentage | Amount |
| Needs | 50% | KSh 30,000 |
| Wants | 30% | KSh 18,000 |
| Savings & Investments | 20% | KSh 12,000 |
This simple structure makes budgeting easier.

Needs are things you must pay for to live and work.
Examples in Kenya include:

| Utilities | KSh 2,000 |

2️⃣ 30% – Wants (Lifestyle Spending)
Wants are things that improve your lifestyle but are not essential.
Examples include:

- shopping
- travel
- subscriptions
Example:
| Spending | Example Amount |
| Eating out | KSh 4,000 |
| Shopping | KSh 5,000 |

3️⃣ 20% – Savings and Investments
This portion goes toward building your financial future.

✔ retirement savings such as contributions to National Social Security Fund
Example:
| Saving Option | Amount |

Why the 50-30-20 Rule Works
This rule works because it:
✔ keeps spending under control
✔ ensures you save consistently
✔ balances needs and lifestyle choices
It is simple enough for beginners to follow.
Adjusting the Rule for Kenyan Salaries
Sometimes expenses such as rent may take a larger portion of income.
If that happens, you can adjust the rule slightly.
Example:
| Category | Possible Adjustment |
| Needs | 55–60% |
| Wants | 20–25% |
| Savings | 15–20% |
The key idea is consistent saving and controlled spending.
Example Budget
Imagine someone earning:
💰 KSh 80,000
Their budget could look like this:
| Category | Amount |
| Needs | KSh 40,000 |
| Wants | KSh 24,000 |
| Savings | KSh 16,000 |
Over a year, saving KSh 16,000 per month equals:
💰 KSh 192,000
