Kogan's FY earnings surge more than 90%

Online retailer Kogan estimates its full-year earnings jumped 90 per cent to $23.7 million after it wrapped up the financial year with a strong fourth quarter.

The ASX-listed retailer says the lift in earnings before interest, tax, depreciation and amortisation came on the back of a more than 40 per cent jump in revenue from last year's $289.5 million.

Kogan says it had 1.4 million active customers at the end of June, up 45 per cent from a year earlier, and was holding cash of $41.99 million.

Founder and chief executive Ruslan Kogan was upbeat about the group's future.

"We are excited about all the growth initiatives we are implementing, as we continue to make the most in-demand products and services more accessible and affordable for our customers," Mr Kogan said in a statement on Tuesday.

Kogan, which listed on the share market in July 2016, has been expanding beyond selling electronics and apparel to take advantage of its extensive database of customers.

The Melbourne-based company now offers travel, insurance, phone and internet services, and last month announced it would start selling its own brand of washing machines, fridges, cooktops and other household and kitchen applications - citing a lack of competition for higher prices in the market.

Kogan's own-branded products will be available before the end of 2018.

Kogan shares were down 19 cents, or 2.9 per cent, to $6.43 in a higher Australian share market at 1030 AEST
