  • I have 6 for personal use, which makes accounting so much easier. I assign a budget at the beginning of the month and at any time I have a good overview of how much I spent for that duration.
    To illustrate, this is how I split my accounts:

    • personal expenses
    • household budget / groceries. This one’s a shared account with my GF
    • savings
    • credit card
    • rent / utilities. Pay in a fixed amount each month, slightly higher than average spending and then not get shafted when insurance or a high electricity bill is due.
    • work travel. This one is the exception. It’s empty unless I travel somewhere for work, then I top it up and at the end I copy and paste all my expenses from this account for travel reimbursement

    I spend less than 15 minutes each month on accounting and the only downside is that I have to set up several budgets and carry a round several cards to pay with. Once a year I go through the accounts and adjust budgets if necessary.



  • The growth (or in this case decline) is exponential. 1.08 is bad, 0.80 is terrifying. 1.08 is roughly half of the fertility needed for a stable population (about 2.1 children per woman). This means that per generation your population shrinks by half its size. 0.8 is another 25% lower. At an exponential rate these differences add up fast. The first one gives you (roughly) one child per 8 great grandparents. The other one needs 18. So over 3 generations the population shrinks by another factor of more than a half.
