Guidance for savings and wage.

Hi everyone

I’m 19 years old, I work a 4 on 4 off position and take home £1849 per month, I have the option to do unlimited overtime so at 6 days a month overtime I end up picking up a little over £2500pm but can pick up more which im doing now)

Current situation money wise – £1849 (no overtime after tax) – £160 rent – £200 taxis – £160 food shopping – £170 debts – £300 holiday money (finish paying it off in December) – £250 – £500 investing in a S&S – £100 fun money

My current goals are – invest more ideally – spending 2 months in America next year (will need to save as much as possible for this) – start saving for house

I love my job and I love doing the extra shifts so I don’t mind working 12+ days in a row

Any help is greatly appreciated
