When I was working full time (I am currently SE, so only working one day a week due to lack of business) I used to give myself £400 a month and I could spend it any which way I wanted without any guilt.
I have always been very good with money and as soon as we get paid I put the following away in individual saving accounts; Christmas, Home insurance, Car insurance and tax so each can be paid in full the next year. I then move enough into our joint for all bills (mortgage, food, sky, life insurance, phones, water, electric, council tax). Then I move my expected tax and NI over too. Any over the £800 (£400 each) fun money gets saved, pre-lockdown this was about £1,500-2000. During lockdown my husband wage has covered the bills and tax. I haven't added to the Christmas pot since March. Then the SE grant has been split, some to cover the tax due on it, and the rest went into the bank to cover any expenses going forward.
Hopefully my work should pick up to 3-4 days in September which will bring me back to a level similar to what I was on before. We are very lucky to have saved hard over the last 3 years and we have a nice amount in the back. We were going to have an extension but have decided against this now due to covid and my loss of earnings.
I have been keener to spend money on our home than going out. We've had quite a few local tradesmen over (trees, wall, tiling) etc so it has been good to know your helping someones family by giving them work. If I am completely honest, I am trying not to look at the bigger picture as it overwhelms me as at my age (30) our future wasn't great now its even worse. I am currently thinking as long as my family is ok for now. I know that's selfish but the whole thing is so depressing.
