I personally save £80/month out of the money OH gives me and I use that for Christmas and birthday presents, but I don't have money left in that account at the end of the year so it's not long term savings.
OH has quite a bit of money spare each month but it all goes into overpaying debts - he took out a loan to extend the lease on our old home before selling it so that needed paying off, and then the mortgage. We won't save properly until all debts are paid off - no savings account is going to earn you more interest than you pay out on a mortgage or other loan so it's financially better to pay off all debt first. Obviously it's good to have money for a rainy day but if you can easily take out a loan if needed, you're best sticking with paying off debt rather than saving. It's crazy how much money you can save by making modest overpayments on loans or mortgages.
