Date the Bill, Then the Cash: Low-Rate Sleeve

The decision is which account holds cash you already know you must spend on a dated bill. A low rate on that cash is not income you can plan a life around. This page does not quote a rate and does not tell you to chase one.

Date first, then the bucket

1. Write the spend date and the amount. If you cannot date it, it is not this page. Undated money is a different decision.
2. Put that amount in an account you can leave on that date without selling a fund. A fund you might be unable to redeem by the spend date fails this page.
3. Do not move the amount into an index fund because the cash rate looks small. The comparison that matters is whether the cash is there on the date, not whether a fund's past year was higher.

Whether a reverse-repo or similar cash tool lets you exit by that date is the reverse-repo page. This page only forces the date and the bucket.

Public-fund rules do not set the rate on a bank or money-market balance. Do not cite a fund prospectus as if it were the rate on your cash account.

FAQ

Is cash at a low rate a mistake?

It is a mistake only if the bill date arrives and the cash is gone. A low rate on money you needed is the cost of having the money. This page does not call that cost a return.

Can I invest the cash and sell the week before the bill?

Only if the product's redemption terms, which you have read, put the cash back before the date. Hope is not a term.

Should I calculate the income I "lost"?

You may subtract two rates you have actually read. Do not invent the fund's future gain to make the cash look foolish.
