NEW YORK, Nov 12 (Reuters) - Discount retailer Dollar General Corp (DG.N) priced shares in its initial public offering at $21 each, at the low end of expectations.

Dollar General, which is almost entirely owned by private equity firm Kohlberg Kravis Roberts & Co [KKR.UL], had expected the shares to sell for between $21 and $23 each.

Dollar General and KKR sold a total of 34.1 million shares, yielding gross proceeds of $716.1 million in the IPO.

KKR, the only shareholder to offer stock in the IPO, is selling 11.4 million shares, after which it will still own 89.5 percent of the company, according to its most recent prospectus.

Dollar General, which is based in Goodlettsville, Tennessee, and operates about 8,577 stores in the United States, is offering 22.7 million shares in the IPO.

Assuming an IPO price of $22 per share, Dollar General had estimated that the IPO would yield net proceeds of $467.8 million. It will use all of its share of the money raised in the IPO to pay down debt.

Dollar General is also planning to pay a fee of about $64 million to KKR and Goldman Sachs & Co (GS.N).

The IPO's underwriters, led by Citi, Goldman Sachs & Co and KKR, have the option to buy another 5.1 million shares.

Dollar General reported quarterly sales of $2.9 billion for the three months ended July 31, up 11.2 percent over the year earlier results. Same store sales, or sales at stores open for at least a year, were up 8.6 percent over the same period.

Dollar General shares are set to begin trade on Friday on the New York Stock Exchange under the symbol "DG."
