Free money tools that do the maths for you.
Budget your salary, plan a savings goal, compare MMF and T-bill returns and check a loan before you sign. Plain language, Kenyan numbers, and it all works on your phone.
Start with the question you are asking.
Each tool answers one everyday money question. Put in your own numbers, read the plain-language explanation under the result, then change one thing and watch what moves.

Your numbers stay on your device.
Salary, rent, loans: these are private. The tools do every calculation inside your browser, so nothing you type is sent to Fnsoko or stored anywhere.
- No account, no sign-up, no tracking of what you enter.
- Close the page and the numbers are gone.
- Want a copy? Email yourself the results. That is the only time we receive anything, and only because you asked.
Get the most out of every tool.
Use real numbers
Your take-home pay and what you actually spend, not what you wish you spent. Rough is fine.
Read the explanation
Under every result is a short note on what it means for you. That is where the learning is.
Change one thing
Move the date, the rate or the monthly amount and watch the result. That is how you find your options.
Talk it through
A calculator gives you a number. The free Financial Clinic helps you decide what to do with it.
Go deeper with the articles.
Short reads that explain the ideas behind the tools: budgeting that sticks, how T-bills and bonds work, and the checks to make before you invest.
Good to know.
Are the Fnsoko tools free?
Yes. Every calculator and game here is free, works on your phone, and does not need an account.
Do you store what I type?
No. The numbers stay in your browser. We only receive your details if you choose to email yourself the results.
Are these tools financial advice?
No. They are teaching tools that show how the numbers work, using illustrative rates. For your own situation, book a free Financial Clinic check-in.
This is financial education, not financial advice. Rates used in the tools are illustrative and change often.
Want a person, not a calculator?
The Financial Clinic is a free check-in where we look at your goals, timelines and options together, in plain language.
