Counting by tens to 100 (trettio, fyrtio...)

Counting by Tens

Most Swedish multiples of ten end in -tio, similar to the English "-ty".

NumberSwedish
30trettio
40fyrtio
50femtio
60sextio
70sjuttio
80åttio
90nittio
100hundra

These numbers never change form to match the noun they modify. As always, the nouns they count must be in their plural form.

She has thirty books.
Hon har trettio böcker.
They have forty guests at the party.
De har fyrtio gäster på festen.
We see a hundred birds in the garden.
Vi ser hundra fåglar i trädgården.

Ages and Prices

Larger numbers are essential for everyday contexts like stating ages and talking about money.

State ages using a number followed by år (years) and optionally gammal (old):

The woman was thirty years old.
Kvinnan var trettio år gammal.
My dad is fifty years old.
Min pappa är femtio år gammal.

For prices, place the number directly after the verb kostar (costs). You don't need to specify the currency if it's clear from context:

Does the jacket cost fifty?
Kostar jackan femtio?
The sweater is cheap and it costs seventy.
Tröjan är billig och den kostar sjuttio.
