How car owners save: a repairs fund, insurance fund and replacement fund (2026)

Most Uber car owners do not fail on a bad week. They fail on a bill they knew was coming: the insurance renewal, four tyres at once, or the year the car becomes too old for the app. The answer is a sinking fund. You put a fixed amount aside every month for a cost you know is coming, so that when the bill arrives the money is already there.

This guide sets up three funds for one car and works out the amounts with real 2026 prices. The car is an example; use your own quotes.

The example car

A 2019 Toyota Axio. Garisea's median asking price for a 2019 Axio was KSh 1,800,000 on 1 October 2026. A car already on Uber Chapchap may stay until 31 December of the year it turns 12, so this car can work on Chapchap to the end of 2031. That is about 63 months from today.

We assume the car does 4,000 km a month. This is an example figure; read your own odometer for a month and use that.

Fund 1: the repairs fund

This pays for anything that keeps the car on the road: services, tyres, brakes, the unexpected.

Services. AutoMag's January 2026 cost survey put a minor service at KSh 12,000–15,000 every 5,000–7,500 km, and a major service at KSh 30,000–35,000 every 20,000 km. Over 20,000 km that is about three minor services (KSh 13,500 each) and one major (KSh 32,500): KSh 73,000, or about KSh 3.65 a kilometre. At 4,000 km a month, that is KSh 14,600 a month.

Tyres. Car & General listed an MRF 185/65 R15 tyre at KSh 7,811 including VAT. Four come to KSh 31,244. AutoMag puts a full set at KSh 25,000–50,000 depending on brand. How long a set lasts depends on roads and driving. As an example, if a set lasts 12 months, set aside KSh 2,600 a month. Write the odometer reading on the receipt when tyres go on, so next time you know.

The unexpected. AutoMag estimated unexpected repairs at KSh 20,000–40,000 a year. A car on Uber all day is likely to need the top of that range. Use KSh 40,000: KSh 3,300 a month.

Repairs fund: about KSh 20,500 a month.

Keep this fund where you can reach it the same day, such as a separate bank or M-Pesa savings account. A car waiting at the garage for money is a car earning nothing.

Fund 2: the insurance and papers fund

These are the yearly bills that come on a date you already know.

Taking insurance at 6% of KSh 1.8 million (KSh 108,000), the year's papers come to about KSh 115,000. Divide by 12: about KSh 9,600 a month.

Two rules for this fund:

• Start the month after you renew. If you renew in March, the fund must hold the full amount by the next March.
• Re-check the value each year. Insurance is priced on the car's value. Ask your insurer what the car is now valued at before you renew.

Fund 3: the replacement fund

Every Uber car has an end date. When it ages off the platform, you sell it and buy the next one. The replacement fund covers the gap between what the old car sells for and what the next one costs.

Garisea's figures on 1 October 2026 show the size of that gap:

• 2019 Toyota Axio: median asking price KSh 1,800,000
• 2015 Toyota Axio, too old to join Chapchap: median KSh 1,320,000

That is a gap of about KSh 480,000. Spread over 63 months, it is about KSh 7,600 a month. These are asking prices from listings, not sale prices, and prices in 2031 will be different. Re-check the gap every year and adjust the monthly amount.

This fund is the one most owners skip. Without it, the only way to replace the car is a new loan, and the business starts over from zero. See when to sell your Uber car for the age rules.

The total, and what it means per day

Over 26 working days that is about KSh 1,450 a day. It comes out of the daily amount before any loan repayment and before your profit. If the daily amount cannot carry it, it is set too low. Test it in the daily amount calculator.

How to run the funds

1. Open three separate accounts. One pot mixed together always gets spent on the nearest bill.
2. Move money the day it arrives. Set a weekly standing order from the account your till pays into. Saving what is left at month end does not work.
3. Put each fund where it fits. Repairs: same-day access. Insurance and replacement: somewhere that earns, such as a money market fund, where withdrawals usually take one to three working days. See money market funds for car savings.
4. Consider a Sacco for the replacement fund. Savings in a Sacco can also raise how much you may borrow. See cash, bank loan or Sacco.
5. Refill after every withdrawal. If the gearbox empties the repairs fund in month four, raise the monthly amount until it is back.

Where Gariboss helps

The funds only fill if the daily amounts come in. Gariboss records each car's daily amount into your own M-Pesa till, matches payments automatically, leaves rest and garage days out of what is owed, and sends you an evening WhatsApp report of who paid. You see the month's real takings before you set the standing orders.
