Switching Budget Methods

How to change your active budget method in Forbidden Finance, what happens to your data, and how to map categories to a new method.

Overview

You can switch budget methods at any time in Forbidden Finance without losing your historical data. Your previous budget is deactivated and preserved in your budget history, while a new budget is created using the method of your choice. The process takes a few minutes and includes a guided category mapping step to help you transition smoothly.

Switching is common and encouraged. Many people try a few methods before finding the one that fits their style. Your past data, transactions, and spending history remain intact regardless of how many times you switch.

How to Switch Budget Methods

Deactivate your current budget

Navigate to Budget, tap the settings icon, and select Deactivate Budget. This closes out your current budget and saves it to your history.

Create a new budget

Tap Create Budget to launch the wizard. Select your new method from the list.

Set up the new method

The wizard walks you through the configuration specific to your chosen method -- income, allocations, groups, and any method-specific settings.

Map your categories

The wizard shows your existing spending categories and suggests how they map to the new method's groups. Review each mapping and adjust where needed. For example, if you are switching from 50/30/20 to Zero-Based, your Needs categories might split across Housing, Food, and Transportation groups.

Review and activate

Check the final summary and tap Activate to go live with your new budget.

What Happens to Your Data

Data	What Happens
Old budget	Deactivated and saved to budget history. You can view it anytime.
Transaction history	Unchanged. All transactions remain with their original categories.
Category definitions	Preserved. Your categories carry over to the new method.
Category-to-group mappings	Need manual review. Different methods use different group structures.
Rollover balances	Reset with the new budget. Accumulated rollovers from the old method do not carry over.
Goals	Unaffected. Goals linked to your old budget continue tracking independently.

Category Mapping Tips

Category mapping is the most important step when switching methods. Different methods organize spending differently, so you need to review where each category lands.

Example: 50/30/20 to Zero-Based

50/30/20 Bucket	Categories	Zero-Based Group
Needs	Rent, Groceries, Utilities	Housing, Food, Utilities (split into separate groups)
Needs	Insurance, Gas	Transportation, Insurance
Wants	Dining Out, Streaming	Entertainment, Subscriptions
Savings	Emergency Fund, Investments	Savings, Investing

Example: Envelope to Kakeibo

Envelope	Categories	Kakeibo Group
Groceries	Groceries	Needs
Dining Out	Restaurants, Coffee	Wants
Books & Classes	Courses, Books	Culture
Emergency Repairs	Home repair, Car repair	Extra

Starting Fresh vs. Building on History

When you switch methods, you can approach it two ways:

Fresh start: Set up the new method based on how you want to budget going forward. Ignore what the old method looked like and configure groups and allocations from scratch. This is best when switching to a fundamentally different approach (for example, from Anti-Budget to Zero-Based).

Building on history: Use your spending data from the old budget to inform your new allocations. Check what you actually spent in each category over the past few months and use those numbers as a starting point. This is best when switching between similar methods (for example, from 50/30/20 to Envelope).

Tips

Switch at the beginning of a month when possible. This gives you a clean start with a full month to test the new method.

After switching, check your budget daily for the first week. Category mappings sometimes need fine-tuning once real transactions start flowing in.

Rollover balances do not transfer between methods. If you have accumulated rollover in your current budget, note the amounts before switching so you can manually account for them in your new setup.
