Your Family's Electricity Use Just Changed, Here's When to Actually Adjust Your Abschlag
Your monthly Abschlag is calculated once, from your prior year's consumption, and then it just sits there, your provider has no way of knowing your household's actual electricity use changed unless you tell them. Three genuinely common family transitions push consumption up in ways the old Abschlag doesn't account for: a parent starting Elternzeit and being home most of the day, someone shifting to home office work, and simply having a child grow from a toddler into a school-age kid with their own devices, longer showers, and more time spent at home. None of these swings are dramatic on their own, home office alone typically adds somewhere in the 70 to 140 euro range per year depending on your setup, but stacked together across a family, they're exactly the kind of gradual shift that produces a Nachzahlung nobody saw coming. You can raise or lower your own Abschlag directly through your provider's online portal (Meine SWM or the equivalent for another supplier) at any point, there's no need to wait for the annual statement to force the correction.
The Official Rule
Your Abschlag, the monthly advance amount your provider charges for electricity or gas, is calculated once, based on your prior yearâs actual consumption and your current tariffâs prices, and then it sits fixed until the next annual reckoning unless you actively change it yourself. It has no way of knowing your householdâs real usage has shifted in between those two points. That gap between what your Abschlag assumes and what your household is actually using is exactly what turns into a Nachzahlung at your Jahresabrechnung, and three genuinely common family transitions widen that gap in ways worth actually planning around, not just discovering a year later.
Elternzeit means a parent who used to be out of the house most weekdays is now home for most of it. That shows up as more laundry cycles, more time with lights and heating running during hours the apartment used to sit empty, and generally higher baseline electricity use simply from more waking hours spent at home. Thereâs no single official multiplier for this since it depends heavily on how your home heats and cooks, but itâs a real, sustained shift, not a one-off.
Home office adds a smaller but genuinely measurable slice on its own. According to energy provider estimates from Vattenfall and Polarstern Energie, a typical home office setup, a laptop with one or two monitors running for a full workday, uses well under a euro a day in electricity, adding up to roughly 70 to 140 euros a year depending on how many days a week youâre actually working from home and how power-hungry your equipment is.
| Change | What actually shifts | What to do about your Abschlag |
|---|---|---|
| Elternzeit | More hours home, more laundry, more heating/cooking during former work hours | Raise it, no fixed multiplier exists, base it on your actual routine |
| Home office | Roughly 70-140 euros/year extra, depending on setup and days per week | A modest raise, more relevant when it stacks with other changes |
| A growing child | More devices, longer showers, more time at home over the years | Recheck periodically rather than assuming usage stays flat |
A growing child adds a slower, cumulative shift rather than a single event. A toddler and a ten-year-old simply donât use the same amount of electricity in a household, more devices, longer showers, more time spent at home rather than at daycare or with a babysitter, all add up gradually enough that it rarely feels like a single moment to react to, which is exactly why itâs worth periodically rechecking your Abschlag rather than assuming a number set years ago is still accurate.
Adjusting your Abschlag yourself is genuinely simple and doesnât require waiting for your provider to notice anything. Through your providerâs online portal, Meine SWM for Stadtwerke MĂźnchen customers, or the equivalent for another supplier, you can raise or lower the monthly amount directly, at any point during the year, not just when a new bill arrives.

What Real People Say
Parent forum threads like urbia.deâs discussion of monthly Abschlag amounts for 4-person households show just how much the ânormalâ number actually varies, families report anywhere from around 63 euros a month for a smaller apartment up to 130 euros for a larger household with more appliances running, which is itself a useful reality check: thereâs no universal correct Abschlag to aim for, only whether yours reasonably matches your own householdâs actual, current situation.
The recurring theme across these discussions is that people rarely think to revisit their Abschlag proactively, it tends to only come up in conversation after a surprising Jahresabrechnung already landed. Parents who did adjust ahead of a known change, going on Elternzeit, starting a regular home office arrangement, describe it as a five-minute task through the providerâs portal that meaningfully softened what would otherwise have been a lump-sum shock months later.
Step by Step
- Notice the trigger, not just the bill: Elternzeit starting, a shift to regular home office days, or simply a child getting older are all genuine reasons to recheck, not just a new Jahresabrechnung arriving.
- Think in categories rather than guessing a single number: more hours home, more appliance use during former work hours, more devices as a child grows.
- Log into your providerâs portal (Meine SWM or your supplierâs equivalent) and adjust your monthly Abschlag directly, this takes a few minutes.
- When genuinely unsure, lean toward a modest overestimate rather than underestimate, a too-high Abschlag comes back as a refund, a too-low one produces a lump-sum Nachzahlung.
- Recheck again after your next Jahresabrechnung arrives, treating it as a signal to fine-tune further, not just a bill to pay.
- If multiple changes stack at once (a new baby and a new home office arrangement, for instance), adjust for the combination rather than assuming each change alone is too small to matter.
Compliance Note
This page explains general patterns in household electricity consumption and how to adjust your own Abschlag, it isnât a substitute for your specific providerâs calculation tools or customer service. Exact consumption changes depend on your homeâs heating and cooking setup, appliance efficiency, and household size, use your providerâs portal or customer service for a number tailored to your actual situation.
FAQ & Common Pitfalls
How much should I actually raise my Abschlag by when I start Elternzeit?
There's no single official figure for this, since it depends heavily on how your home heats and cooks (electric versus gas), how many hours you're actually home compared to before, and the season. What's genuinely useful is thinking about it in categories rather than guessing a lump number: more laundry cycles from a baby in the house, more time with lights, heating, and any electric cooking appliances running during hours you used to be at work or your child was at Kita, and generally higher baseline usage simply from spending more waking hours at home. A reasonable starting move is raising your Abschlag by something in the range other parents in similar households report, rather than leaving it untouched and finding out the gap at your next Jahresabrechnung.
Is it really worth adjusting for something as small as one or two home office days a week?
On its own, honestly, the swing is modest, provider estimates put a single home office workday's electricity use (a laptop and a couple of monitors running for a normal workday) at well under a euro a day, adding up to roughly 70 to 140 euros a year depending on your setup and how many days a week you're actually home. Where it matters more is when home office stacks with other changes already happening in the household, a new baby, a partner also working from home more, a heating season that runs colder than usual, since none of these show up as a single dramatic number, but together they're exactly the kind of gradual shift that produces a surprise at your annual settlement.
If I raise my Abschlag and it turns out I overestimated, do I lose that money?
No, overestimating isn't a real risk the way underestimating is. If your adjusted Abschlag payments end up higher than what you actually used over the year, your Jahresabrechnung will simply show a Guthaben, a credit, and that difference gets refunded to you (directly if you have a SEPA direct debit mandate on file, or once you provide your bank details if you don't). The actual asymmetry worth understanding is that a too-low Abschlag produces a single, larger Nachzahlung you have to find all at once, while a too-high one just comes back to you as a refund, which is exactly why it's reasonable to lean toward slightly overestimating during a genuine household change rather than underestimating.
