Split the fare by stretch: each part of the ride is shared equally by the people still in the car. On a $40 fare with a 20% tip, a $48 total, riders going 12, 8 and 3 miles pay $30, $14 and $4. If everyone gets out at the same place, divide the total equally.

Key points:
- Same drop-off means an equal split. Different drop-offs mean each stretch of the ride is shared by the riders still in the car.
- On a $48 total, riders going 12, 8 and 3 miles pay $30, $14 and $4. An equal split would charge each of them $16.
- Split the tip in proportion to each fare share, put a toll on the stretch where it was paid, and treat surge as part of the fare.
- In EvenOut, enter the stretch results under "Exact amounts". "By shares" typed with the miles would charge the 3-mile rider $6.26 instead of $4.

## How do you split an Uber or Lyft fare fairly?

It depends on where each person gets out. If everyone rides to the same place, divide the total by the number of riders. If people leave at different stops, split the fare by stretch, so that each part of the ride is paid for by the riders still in the car during that part.

Check the options in the ride app you use, since an app may have its own way to divide a fare. Whatever it offers, the shares below are the numbers to put into it. Everything on this page is arithmetic, so it holds for any ride.

## When is an equal split fine?

When everyone goes to the same address, or the drop-offs are close together. Three friends who ride to the same restaurant share a $48 total (a $40 fare plus a 20% tip) at $16 each, and nobody is overcharged.

An equal split goes wrong when the drop-offs spread out. Say the same $48 ride drops one friend after 3 miles, another after 8 and the last after 12. At $16 each, the 3-mile rider pays the same as someone who rides four times as far.

## How does the stretch method work?

Cut the ride into stretches at each drop-off, price each stretch, and divide each one by the number of riders in the car. Use the total you paid, tip included. Here $48 over 12 miles is $4 a mile, and the three stretches cost $12, $20 and $16.

| Stretch (miles) | Length | Cost at $4 a mile | Riders in the car | Each pays |
|---|---|---|---|---|
| 0 to 3 | 3 | $12 | 3 | $4 |
| 3 to 8 | 5 | $20 | 2 | $10 |
| 8 to 12 | 4 | $16 | 1 | $16 |

Each rider pays for the stretches they were in the car for. The 3-mile rider pays $4. The 8-mile rider pays $4 + $10 = $14. The 12-mile rider pays $4 + $10 + $16 = $30, and the three amounts add back to $48.

| Rider | Equal split | By stretch | Difference |
|---|---|---|---|
| Gets out at 3 miles | $16 | $4 | $12 less |
| Gets out at 8 miles | $16 | $14 | $2 less |
| Gets out at 12 miles | $16 | $30 | $14 more |

This is the rule proposed for sharing airport landing charges: each increment of cost is paid by everyone who needs it. A 1973 paper by Littlechild and Owen showed that it gives the Shapley value, a standard game-theory way to divide a shared cost. It treats the fare as growing evenly with distance along one route. A minimum fare or a long wait bends that a little, so read the result as a fair estimate and not an invoice.

## Why does "By shares" with the miles give a different answer?

Shares charge in proportion to distance, and the stretch method does not. Typing 3, 8 and 12 as shares makes 23 shares, so $48 gives about $2.09 a share. The 3-mile rider would pay $6.26 instead of $4, the 8-mile rider $16.70 instead of $14, and the 12-mile rider $25.04 instead of $30.

The gap exists because the first 3 miles are shared by all three riders, and shares do not know that. So work out the stretch amounts first and enter them under "Exact amounts".

## How do you split the tip, tolls and surge?

Split the tip in proportion to each person's share of the fare. The fare without the tip is $40, which the stretch method divides into $3.33, $11.67 and $25.00. A 20% tip on each is $0.67, $2.33 and $5.00, so the totals are $4.00, $14.00 and $30.00, the same as before. Splitting the $8 tip equally ($2.67 each) would make the 3-mile rider pay $6.00 and the 12-mile rider $27.67.

A toll belongs to the stretch where it was paid. Say a $6 toll falls between mile 8 and mile 12. Only the 12-mile rider was in the car there, so that rider owes $36. A $6 toll before the first drop-off is shared by all three, $2 each. A flat airport fee goes to whoever uses the airport, or to everyone when the whole group is going there. Agree on this before the ride and not at the curb.

If the fare includes surge pricing, use the total you were charged as the fare. The method divides whatever the total is, so surge needs no extra step.

## Who pays the driver, and how do the others pay you back?

Usually one person orders the ride and pays, and the others pay that person their shares. Say you ordered and rode 8 miles. You paid $48, your own share is $14, so the 3-mile rider owes you $4 and the 12-mile rider owes you $30.

To record it in EvenOut:

1. **Add one expense for the full $48.** Pick the group or friend under "With", and leave it as "Paid by you". "Who paid?" lists every member, so you can also pick someone else.
2. **Choose "Exact amounts" in the "How to split" sheet** and type $4, $14 and $30 next to the three names. The pill reads "$X left to assign" until the amounts match the total, then "All assigned".
3. **Save it.** Each rider's balance with you updates.
4. **Record each payment with "Settle up".** EvenOut records the payment only and does not move money, so the transfer itself goes through whatever you normally use.

## What should you do next?

Agree on the method before the ride: equal when the drop-offs match, by stretch when they do not. The [rideshare fare split calculator](https://www.evenoutapp.com/tools/rideshare-fare-split-calculator) runs the stretch math from the fare and each rider's distance. For a ride in a taxi, [how to split a taxi fare](https://www.evenoutapp.com/guides/how-to-split-a-taxi-fare) works the same idea through a meter fare with a booking fee.

When the ride is in someone's own car, the costs are different. [How to split carpool costs](https://www.evenoutapp.com/guides/how-to-split-carpool-costs) covers gas, parking and wear, and [splitting a bill with tax and tip](https://www.evenoutapp.com/guides/split-bill-with-tax-and-tip) covers the tip arithmetic in a restaurant.

## Frequently asked questions

### What if riders are picked up at different places?

The same idea works along the route: each stretch is shared by the people in the car during that stretch. Say a 10-mile ride costs $30, or $3 a mile. Ana rides all 10 miles and Ben joins at mile 4. The first 4 miles ($12) are Ana's alone, and the last 6 miles ($18) are shared at $9 each. Ana pays $21 and Ben pays $9.

### How do you handle the odd cent?

An equal split in EvenOut shares out the remainder cents, so $25.00 across three people comes to $8.34, $8.33 and $8.33. With "Exact amounts" you type each figure yourself, so round two shares and give the leftover cent to the biggest one. The pill reads "All assigned" once the amounts match the total.

### What if you take the same ride every week?

Work it out once and enter it as one expense with "Exact amounts". Next time, use "Duplicate expense", or set "Repeat" to "Weekly" so EvenOut adds each one with the same payer and split. If the fare changes, stop the repeat under "Repeating expenses" and add a new one at the new amounts.
