Week 8
$230.00 goes out every week and the next payment is not there in time. Week 8 is the worst of it at -$140.00.
Add the term up and it works: $3,000.00 in against $2,760.00 out, ending at $440.00. Walk it week by week and it fails in week 8 anyway, because the money that balances the column has not arrived yet. This is the gap a termly total cannot show, and it is the ordinary way a funded student ends up borrowing.
$140.00 more at the start of the term is enough for no week to close below zero. That is the figure to take to a hardship fund or an overdraft conversation, and it is usually far smaller than the number people ask for, because what is missing is timing rather than money.
A payment is treated as landing at the start of the week it is entered against, and that week’s costs come out afterwards. Every figure is yours: no instalment calendar, typical rent or average food bill is built in anywhere, because those differ by country, by provider and by year, and a stale default would be worse than an empty box.
Costs that fall once rather than weekly — a tenancy deposit, textbooks, a flight home — are the usual reason a plan that looked fine collapses. Either spread one across the weeks it has to be saved from, or put it in the opening balance as a subtraction, and do it before the week it is due rather than after.
Money arrives in lumps and leaves in a trickle. An instalment lands at enrolment, another one lands months later, and in between the rent, the food and the bus fare go out every single week without asking whether anything has arrived recently. Totalling the term hides that completely: income and outgoings can match to the penny across twelve weeks and still leave somebody with an empty account in week eight.
So this planner does not report a termly total as its answer. It walks the balance through the term one week at a time, applying each payment in the week you say it lands and taking the week’s costs out afterwards, and reports the first week the balance goes below zero. That week is the output. The totals are underneath it as supporting evidence, which is the correct order.
Consider a twelve-week term opening with 200, two payments of 1500 arriving in weeks one and nine, and 230 going out weekly. The term adds up to a surplus: 3200 in against 2760 out, closing 440 up. Walk it week by week and the balance falls to 90 in week seven and to minus 140 in week eight, one week before the second payment. The surplus is real and it is in the wrong place.
This is the ordinary way a fully funded student ends up on an overdraft, and it is entirely a problem of timing rather than of amount. Seeing week eight in September gives you a term to act on it. Discovering it in week eight gives you an expensive weekend.
Because the shape of the problem is timing, the useful figure is not the deficit. It is the smallest amount that, added at the start, would keep every week from closing below zero — the depth of the dip rather than the size of the term. In the example above that is 140, not 2760, and the difference between those two numbers is the difference between a request somebody can say yes to and one they cannot.
That is the figure to take to a hardship fund, a university short-term loan office, or a conversation with a bank about an arranged overdraft for a defined period. It is also the figure to take to a landlord when asking whether one rent payment can move by three weeks, which is often free and solves the whole problem outright.
One-off costs are the usual culprit. A tenancy deposit, a laptop, textbooks in week one, a flight home at the end — none of them are weekly, and dropping them into a weekly average smears them across a term they do not belong to. Either subtract a one-off from the opening balance if it falls at the start, or raise the weekly figure for the stretch you must save it out of, and do that before the week it is due.
The second culprit is optimism about the weekly figure. Use what last month actually cost from a bank statement rather than what a week ought to cost, and count the payment as arriving on the day it clears rather than the day it was promised. Nothing here supplies a rent, a food budget or an instalment calendar, because those differ by country, provider and year, and a plausible default would quietly become the answer.
The week it reaches your account, not the week it is scheduled or the week term starts. Payments that clear on a Friday effectively belong to the following week, and being one week optimistic here moves the whole answer by one week.
Wages paid weekly are best handled by subtracting them from your weekly costs, so the tool tracks the net drain instead. A monthly wage is better entered as separate payments in the weeks it actually arrives, since that is the shape it has.
It says these figures never run out, which is a different claim. Check the tightest week the tool reports: a term whose lowest point is a few pounds has no room for a broken phone, and a plan without any slack in it is one unexpected bill away from the other answer.
Include it only if it is reliable and you know when it lands, entered in the week it lands. Contributions that arrive when asked for are genuinely useful in a crisis but modelling them as scheduled income hides the very gap you are trying to see.
