About this calculator
Start from the suggested split, then change any line to match your real spending.
How it's worked out
Enter your take-home pay, the amount that lands in your account after PAYE, NSSF, SHIF and the housing levy. If you don't know it, work it out first with our Kenya PAYE calculator. Every line starts at a suggested share of your pay. Change any line to what you spend in a normal month, and the totals update as you type.
The calculator groups the lines the way the 50/30/20 rule does: about 50% for needs, 30% for wants and 20% for savings and paying off debt. The rule was made popular by Elizabeth Warren and Amelia Warren Tyagi in their book All Your Worth. In Kenya, rent and food often take more than half on their own, so treat the targets as a direction to move in, not a pass mark.
Check food and transport first. Prices are rising fastest on those two lines. Kenya's inflation reached 7.3% in October 2026, with transport costs up 17.1% in a year as fuel prices climbed (Citizen Digital). The Central Bank of Kenya publishes the monthly figures on its inflation page. If last year's budget still has last year's fare, it's out of date.
Where to put the 20%. Build an emergency fund of three months' needs first, then grow savings in a money market fund or a savings app. To plan a bigger goal, use the savings goal calculator. A chama can help too, because the group keeps you saving.
Frequently asked questions
What is the 50/30/20 budget rule?
Spend about 50% of your take-home pay on needs (rent, food, fare, bills), 30% on wants and 20% on savings and paying off debt. It's a simple check on whether your spending is balanced.
How much of my salary should go to rent in Kenya?
A common guide is no more than 30% of take-home pay. On KSh 50,000, that's KSh 15,000. Above that, there's little left for food, fare and savings.
Is black tax a need or a want?
That's for you to decide. If supporting your parents or siblings is a fixed commitment, treat it as a need and plan the rest of your budget around it. The calculator lists it under wants only to follow the 50/30/20 layout.
How do I budget on a small salary?
Cover needs first, then save something every month, even KSh 500, so the habit is there when your pay grows. Cut the most expensive debt, usually mobile loans, before adding new wants.
