Foo - What should I charge?

Yesterday as I was arriving from a ride my neighbor asked if I fixed bikes and if I would fix his . I was given two bikes, one newer mountain bike and one older bike. He told me whatever it will cost, to fix them. I am not sure what to charge! The parts I had to buy [chain, tube, cable kit] was 20$. The newer bike needed a tube which I had, and he wanted taller handlebars which I had. I spent about 2 hours on the newer bike and about 3 hours on the older bike. I am thinking of just doubling my cost, 40$, yet I know it would of cost 100$+ for the shop to do it.

So. . . what should I do fellow Foosters?

$40

Charge him for parts, and keep the favor in your back pocket.

Depends. If your neighbor is cool and in a position to help you out sometime, you might consider just charging him for the parts. Not regularly, but as a one time favor. Favors like that have a way of working their way back to you.

charge him for the parts for now and i agree keep the favor

Parts, a fair price for the stuff you had, and call it even.

Charge him for the parts, including the ones you already had on hand. Tell him labor was free, this time. ;)

Seriously, it's nice to have a favor in the bank, and to simply do something nice for someone else. Unless you're really thinking of turning wrench, just charge cost for all parts and consider him down the road when you need a favor with which he can help you.... :)

You neglected to tell us how well you get on with the neighbour.

I would charge him for all the parts including what you had on hand, so I would guess around the $40 is fair enough.

Parts.

Are lots of neighbors going to follow suit and ask you for help? If so, start establishing a fair market price. You can discount for neighbors you're especially friendly with, but make it clear that you believe there is actual value to your efforts. If parts are worth, say, $40 (including parts you had on hand) and it really is a 5 hour job, then $100 certainly isn't unreasonable. That's $12/hour for labor. If this is a one off deal, then if it's a neighbor you're friendly with, I'd charge for parts, rounded up to some round number.
