AccountingFilter: Client convenience aside, does receiving "instant payment" for my services via PayPal make financial sense rather than waiting for a check to come in the mail 30 days later? Help me unlock the secrets of the Time Value of Money.
I'm sure this is a complete textbook example of TVM, but humor me.
An example:
Let's say that on July 1st, I perform work for a client, and the total for the work is USD $150.
In which scenario do I come out ahead on July 31?
Scenario A.) In which I process an "instant payment" for the client at the time of the services, and the client pays immediately via PayPal. PayPal takes out their 3%+$.30. I get the rest, and put it into my high-interest savings account which earns 5% annually and compounds monthly.
or
Scenario B.) In which I wait 30 days for a check to arrive in the mail, deposit the check's funds into the same 5% high-interest savings account. Assume that the check clears instantly, and that I have access to the full $150 on July 31.
So far, my guess is that if the 30-day window were expanded to 90 or 120 days, it would make sense to get-what-you-can right now, paypal fees be damned, but at 30 days, waiting for the check nets me more money.
I've checked out the wikipedia entry for
Time Value of Money, but can't figure out the interest rate (decimal or integer?), period (month? year?). It sounds so easy, but my brain keeps getting in the way when it sees the equations.
The equations are fine if you want an exact number. No need to bother with them if you're just looking for a rough estimate.
