When you put KES 5,000 into a money market fund this month, KES 7,500 in October and KES 10,000 in November, and at 10% a year you walk into December with KES 22,835. Over three months the saving does the work and the interest is a rounding error.

Save KES 5,000, 7,500 and 10,000 from September into a money market fund and here is what January looks like.

We used 10% because it keeps the arithmetic round. The Jubilee Money Market Fund (KES) quoted 10.61% as at 1 September 2026, and money market yields move with the Central Bank rate, so treat every figure here as an illustration.

Njaanuary, njaa being the Swahili for hunger, is the month that the December money runs out. It is a joke in Kenya because it is true for most people.

Kenyans moved KES 722.53 billion through mobile money agents in December 2025 and KES 699.64 billion in January 2026, according to the Central Bank of Kenya. Infotrak polled 1,000 adults on 19 and 20 December last year and 55% said they would not be celebrating Christmas at all, five points more than the year before, with 78% of them citing money. Nairobi to Kisumu by bus was KES 1,750 to KES 2,000 one way in the week before Christmas 2025, and a flight to Mombasa was KES 19,500 at peak against KES 9,300 at year end.

Then January arrives with the bill that does not move. The 2026 senior school fee structure splits the year 50:30:20 across the three terms, so a boarding school parent paying KES 53,554 a year owes about KES 26,777 in the first week of January. Day schools are free at senior level. Everyone else is buying uniforms and books in the same week the landlord asks for rent.

Save KES 5,000, 7,500 and 10,000 from September into a money market fund and here is what January looks like.

The obvious place to save is where you already are: M-PESA, or the savings pocket in your banking app. The problem with both is that the money is one tap from spending.

A money market fund is a slower wallet. The Jubilee Money Market Fund (KES) takes deposits from KES 100 by M-PESA paybill 4103749, credits interest monthly, and pays withdrawals within 2 working dats, to your bank or M-PESA. Requests after 9:00 AM on a business day are valued the next business day, so a Friday afternoon request comes back Monday or Tuesday. That is slow enough to stop an impulse and fast enough for a matatu ticket. There is no lock-in, no exit fee and no penalty for taking the money out in December, which is the difference between this and a fixed deposit.

The yield, for what it is worth over three months, is the same 10.61% (as at 1st September 2026) whether you hold KES 100 or KES 100,000. Our guide to how money market funds work covers the mechanics.

We keep coming back to one number. Kenya’s average smartphone selling price has nearly tripled since 2019, to KES 18,979, and the way many people now afford one is a financing plan at KES 30 to KES 100 a day. Those plans work because the daily amount is small enough to ignore. By the end of the contract you have typically paid two to three times the sticker price.

Point the same habit the other way. KES 50 a day from 1 September to 31 December is KES 6,100. It does not cover the school fees. It does cover the bus fare home for a family of three, and it comes back to you with interest instead of costing you double.

Save KES 5,000, 7,500 and 10,000 from September into a money market fund and here is what January looks like.

If you can do more than KES 50 a day, the KES 5,000, 7,500, 10,000 ladder above is a realistic version for someone whose salary can spare a bit more each month. Hold it one more month, through December, and the fund balance reaches about KES 23,025 before tax, with roughly KES 445 of net interest, in time for the January fees.

Open a Jubilee Money Market Fund (KES) account. You can do this easily online by visiting their investment platform, the Jubilee Asset Management JAMHub Digital portal, on your mobile phone, tablet or laptop browser. Once a Jubilee Money Market Fund (KES) account has been opened, you can make your first KES 100 deposit; the point is that the account exists before the December salary lands. Send the monthly amount on payday, before the rest of the salary has somewhere to go. And withdraw in the week you travel, not the week you get paid.
