You’ve been putting $200 a month into an Emergency fund envelope for a year. The envelope reads $2,400, which is the point. But your budget’s Available to spend also reads $2,400 higher than it should, which is not. Every rollover envelope has this problem: the balance that makes it a savings envelope is the same balance your budget treats as spendable. We built Reserved categories to fix that. Mark the envelope as reserved and its surplus leaves the headline number, while the envelope itself keeps showing exactly what you’ve saved. Small switch, and it fixes the number you probably check most.

The problem with a savings envelope

The envelope system started with literal envelopes. Grocery cash in one, gas cash in another, and when an envelope was empty, you were done. Our rollover categories are the digital version, minus the paper cuts. Whatever’s left in a rollover envelope carries into next period, which is perfect when you’re saving up for something.

Trouble is, your budget treats every leftover dollar the same. Surplus from every envelope piles into Available to spend. Forty bucks left in Dining? Sure, count it, that’s fair game. The $2,400 sitting in Emergency fund? Different story. You could technically spend it, but the whole reason it exists is that you won’t. So the number you glance at to decide whether you can afford the thing in your cart has been quietly inflated by the money you’ve promised not to touch.

What Reserved does, and what it leaves alone

One change, and only one: a reserved category’s surplus no longer counts toward Available to spend.

The envelope’s own row doesn’t budge. It still shows every dollar in there, so you get to watch the fund climb. No money shuffles between categories, no balance resets, and if you flip Reserved off, the surplus drops straight back into the total. Think of it as changing the math, not moving the money.

Overspending still counts. If a reserved category goes negative, it reduces your Available to spend by the full shortfall, the same as any other category. Reserved can hide savings from the headline. It can’t hide a hole.

Where you’ll see it

Look for a little lock beside the available amount on the category row. The amount is the same as before. The lock just says “hands off, this one’s set aside.” In the Spend summary, a Reserved line appears in the running total as a deduction, so Available to spend drops to the spendable figure and the math still balances when you read down the column.

Parents only get the lock when all their children are reserved. Mixed family? No lock on the parent. And the Plan tab is unaffected, because assigning funds is about allocating money rather than spending it, so it still counts every envelope. The iOS widget’s available number respects Reserved too.

When to reserve a category

Rule of thumb: reserve envelopes you’re filling up, not ones you’re emptying.

  • An emergency fund, a balance you want to grow and leave alone
  • Sinking funds, where you save toward a known future expense like car maintenance, annual insurance, or the holidays
  • Long-term savings goals you keep inside your budget rather than in a separate account

Keep everyday spending categories un-reserved so their surplus shows up as available. If you’re using something like the 50/30/20 split, Reserved is how your 20% stops leaking into the 30%.

Budgets created from our starter template now reserve Transfer to Savings from the start, so new Skwads get this behavior without touching a setting.

How to turn it on

Open your budget, pick a category, and open its options. On a rollover category you’ll see a Reserved toggle. Flip it, and the lock appears on the row and the Reserved line appears in your Spend summary. On a basic category the toggle shows grayed out with a note, because a category that resets each period has no balance to protect. Switch it to rollover first if you want to reserve it. The reserved categories guide has the details. New to how balances carry between months? Start with adjusting a budget without changing history.

Frequently asked questions

Does turning on Reserved move any money? Not a cent. Reserved changes how the budget does its math and what it shows, nothing more. Switch it off and the surplus is back in Available to spend right away.

What happens if I overspend a reserved category? Oh, it counts. A reserved envelope in the red knocks the full shortfall off Available to spend, just like any other category would. Reserved tucks savings out of sight. Overspending it never gets tucked away.

Why can’t I reserve one of my categories? Reserved only works on rollover categories. A basic category resets every period, so there’s no balance to protect. Make it a rollover category and the toggle shows up.

Does Reserved change the Plan tab? Nope. Assign funds is about handing out money, not spending it, so Plan still counts every envelope.
