Split your take-home pay into needs, wants, and savings.

Worked example

Take a gross monthly salary of KES 120,000. The budget works off take-home pay, not gross, so it first runs the Kenyan payslip and finds a net of about KES 85,023. It then applies the 50/30/20 rule to that net. Half goes to needs, which is KES 42,511. Thirty percent goes to wants, which is KES 25,507. The final fifth, KES 17,005, goes to savings or paying down debt.

The three buckets add back to the KES 85,023 net.

How it is calculated

The 50/30/20 rule is a starting framework for sharing out take-home pay. The tool runs your gross salary through the full Kenyan payslip, deducting NSSF, SHIF, the Affordable Housing Levy, and PAYE after the personal relief, then splits the resulting net into three fixed shares: 50% for needs, 30% for wants, and 20% for savings or debt repayment. Needs are the costs you cannot easily avoid, such as rent, food, transport, school fees, and minimum loan payments. Wants are discretionary spending. The final fifth builds your emergency fund, pension top-ups, or extra debt repayments. Treat the percentages as a guide rather than a rule: in higher-cost cities like Nairobi, needs often run above 50%, in which case trim the wants bucket before the savings one. The value of the framework is that it forces a savings allocation up front rather than leaving it as whatever happens to be left at month end.

Frequently asked questions

How does the 50/30/20 budget work in Kenya?
The rule splits your take-home pay into three parts: 50% for needs such as rent, food, transport, and loan repayments, 30% for wants such as entertainment and eating out, and 20% for savings and extra debt repayment. It works on net pay after PAYE, NSSF, SHIF, and the housing levy, since that is what actually reaches your account. Treat it as a starting frame and adjust the shares to your own costs.
What counts as a need versus a want in Kenya?
Needs are costs you cannot skip without serious consequences. In a Kenyan context these typically include rent or mortgage payments, electricity and water bills, food at home, public transport or fuel for commuting, school fees, and minimum loan repayments. Wants are anything discretionary such as eating out at a restaurant, streaming subscriptions, or upgrading a phone that still works. If you could comfortably go a month without it, it is usually a want.
What statutory deductions reduce take-home pay in Kenya?
Four deductions come off your gross salary before you see a shilling. NSSF takes a tiered contribution based on your pensionable pay. SHIF replaced NHIF and is charged at 2.75% of gross salary. The Affordable Housing Levy is 1.5% of gross, matched by your employer. PAYE is calculated on the remaining taxable income using the progressive rate bands, with a personal relief of KES 2,400 per month reducing the tax owed. All four are factored into the net pay figure this calculator shows.
Should I save 20% of gross or net pay in Kenya?
The 50/30/20 rule always applies to net pay, not gross. Your NSSF contribution already leaves your account before you see your salary and counts as forced retirement saving, but the 20% savings bucket in this calculator refers to voluntary saving on top of statutory deductions. Starting with 20% of net is a solid target. If your needs genuinely exceed 50% of net, which is common in Nairobi, reduce the wants bucket first before cutting savings.
