So, using an exchange rate of 2.4 TL / £
1 year = 888 TL
2 year = 1,752 TL
3 year = 2,616 TL
4 year = 3,480 TL
5 year = 4,344 TL
To calculate the costs of a permit for any periods not covered above it's £40 for the first month and £30 for each subsequent month, However, for UK citizens payment must be made in Turkish Lira at the published exchange rate on the day of application.
So, at 2.30 TL / £ it'll cost 851 TL for a 1 year permit, but at 2.70 TL / £, it'll be 999 TL.
