Understanding Budget Rollover
Rollover is HOB's flexibility feature. Didn't spend your entire grocery budget? It carries forward. Overspent on gas? Next month's budget starts lower. This guide explains how rollover works and when to use it.
What is Rollover?
Rollover automatically carries unused budget (or overspending) from one month to the next. It's HOB's way of making your budget flexible while keeping you honest.
✅ Underspending = More budget next month
You budgeted $400 for groceries but only spent $350.
Next month, you automatically start with $450 to spend on groceries ($400 new budget + $50 rollover).
⚠️ Overspending = Less budget next month
You budgeted $200 for gas but spent $250.
Next month, you automatically start with $150 for gas ($200 new budget - $50 overage).
🔄 The Rule
Rollover = (Budgeted - Spent). Positive rollover adds to next month. Negative rollover subtracts from next month.
When to Enable Rollover
Not every category should have rollover enabled. Here's how to decide:
✅ Good rollover categories (variable spending):
- Groceries - Some months you stock up, some months you eat down the pantry
- Gas - Usage fluctuates based on trips and driving patterns
- Entertainment - Some months are busier than others
- Clothing - Buy when you need it, save when you don't
- Gifts - Save up across months for birthdays and holidays
- Medical - Health expenses are unpredictable
- Home Maintenance - Save for the big repair you know is coming
❌ Bad rollover categories (fixed expenses):
- Rent/Mortgage - Same amount every month, no rollover needed
- Insurance - Fixed monthly premium
- Subscriptions - Netflix doesn't cost more or less each month
- Debt Payments - Minimum payment is fixed
- Utilities - While they vary, most people budget the average and absorb small differences
🤔 The Test
Ask yourself: "Does this expense vary from month to month based on my usage or needs?" If yes, enable rollover. If no, leave it off.
How Rollover Works in Practice
Let's walk through a real example over 3 months.
Example: Grocery Budget with Rollover
January
Budgeted: $400
Spent: $350
Rollover to February: +$50
February
Budgeted: $400
Rollover from January: +$50
Available: $450
Spent: $480 (stocked up at Costco!)
Rollover to March: -$30
March
Budgeted: $400
Rollover from February: -$30
Available: $370
Spent: $365
Rollover to April: +$5
Notice how February's overspending didn't break the budget - it just reduced March's available amount. This is rollover in action!
Enabling Rollover for a Category
Rollover is enabled by default for most categories in HOB, but you can turn it on or off for any category.
To enable/disable rollover:
- Go to Categories
- Click on the category you want to modify
- Click Edit Category
- Check or uncheck Enable Rollover
- Click Save Changes
💡 Pro Tip
When you first enable rollover on a category mid-year, start fresh. Don't try to calculate historical rollover - just begin from this month forward.
Viewing Rollover Amounts
On the Budget page, you can see rollover amounts for each category.
The budget page shows:
- Budgeted: What you set for this month
- Rollover: Amount carried forward from last month (+ or -)
- Available: Budgeted + Rollover (what you can actually spend)
- Spent: What you've spent so far
- Remaining: Available - Spent
Green rollover number: You have extra from last month! 🎉
Red rollover number: You overspent last month and need to make up for it this month ⚠️
Using Rollover Strategically
Rollover isn't just automatic - you can use it intentionally to save for big expenses.
Example: Saving for Christmas
Create a "Christmas Gifts" category with rollover enabled.
- Budget $100/month starting in January
- Don't spend anything from January-November
- By December, you have $1,100 saved up ($100 × 11 months)
- Spend it guilt-free on gifts!
This works great for:
- Annual insurance premiums
- Car registration
- Vacation funds
- Holiday shopping
- Home repairs you know are coming
✅ This is Called a "Sinking Fund"
You're saving a little each month so when the big expense arrives, the money is already there. No scrambling, no stress!
Resetting Rollover
Sometimes you want to start fresh and clear all rollover amounts.
When to reset:
- You're starting a new year and want a clean slate
- You've made major budget changes and old rollovers don't make sense anymore
- A category has accumulated a huge rollover balance you want to reallocate
To reset rollover:
Simply adjust your budget amount for the month to account for the rollover, making the "available" amount what you actually want. The rollover will naturally zero out as you spend.
📝 Example
Groceries has $200 positive rollover, but you want to start fresh at $400 available.
Budget only $200 this month. Combined with the $200 rollover, you'll have exactly $400 available. Next month, go back to budgeting $400.
Common Questions
Q: What if I overspend a category without rollover?
A: You'll need to manually move money from another category to cover it. Without rollover, overspending doesn't affect next month - but you still need to balance this month's budget.
Q: Can I have some categories with rollover and some without?
A: Yes! Every category can have rollover enabled or disabled independently. Mix and match based on what makes sense.
Q: Does rollover work with income categories?
A: Rollover is primarily for expense categories. Income doesn't typically "roll over" in the same way.
Q: What happens when I copy last month's budget?
A: HOB copies your budgeted amounts and automatically calculates rollover from last month's spending. You don't need to do anything manually!
