STOCKHOLM, Sept 15 (Reuters) - Winners of this year's Nobel Prizes will get an extra 1 million crowns, taking the total financial reward to 11 million Swedish crowns ($986,000), the Nobel Foundation, which administers the awards, said on Friday.

The prize money has been adjusted up and down in recent years and the award-givers said it was increasing the amount this year to reflect the Foundation's stronger financial position.

In 2012, prize money was reduced from 10 million crowns to 8 million as the Foundation looked to shore up its finances. The prize amount was increased to 9 million in 2017 and in 2020 to 10 million - where it was prior to 2012.

Over the last decade, however, the Swedish crown has lost around 30% of its value against the euro meaning the most recent increase in the value of the prize won't leave winners outside Sweden feeling much richer. EURSEK=

In 2013, the prizes for achievements in science, literature and peace - which were first awarded in 1901 - were worth around 1.2 million dollars, despite the cut in the Swedish currency sum to 8 million crowns.

The Nobel Prize in Physiology or Medicine is the first of this year's prizes and will be announced on Oct. 2 followed by Physics, Chemistry, Literature and Peace on the following days.
