50/30/20 Budget

How to set up and use the 50/30/20 budget method in Forbidden Finance, splitting your income into Needs, Wants, and Savings.

Overview

The 50/30/20 budget splits your after-tax income into three buckets: 50% for Needs, 30% for Wants, and 20% for Savings. It is one of the most popular budgeting frameworks because it is simple to understand, quick to set up, and flexible enough for most financial situations. This method is available on the Free tier.

The core idea is balance. You ensure your essentials are covered, give yourself room to enjoy life, and consistently build savings -- all without tracking every individual purchase. Forbidden Finance tracks your adherence to each bucket and shows you an overall score so you always know where you stand.

How to Set Up Your 50/30/20 Budget

Open the Budget Wizard

Navigate to the Budget tab and tap Create Budget. Select 50/30/20 from the method list.

Enter your monthly income

Enter your total monthly take-home pay. This is the amount after taxes and payroll deductions.

Adjust your percentages (optional)

The default split is 50/30/20, but you can adjust the percentages to fit your situation. For example, if you live in an expensive city, you might use 60/20/20. The three percentages must add up to 100.

Assign categories to buckets

Drag your spending categories into the appropriate bucket. For example:

Needs: Rent, Utilities, Groceries, Insurance, Minimum debt payments
Wants: Dining out, Entertainment, Subscriptions, Hobbies
Savings: Emergency fund contributions, Investments, Extra debt payments

Activate your budget

Review the summary and tap Activate. Your budget is now live.

Reading Your Progress

Each bucket shows three key metrics:

Metric	What It Means
Allocated	The dollar amount assigned to this bucket based on your income and percentage
Spent	How much you have spent in categories assigned to this bucket
Adherence	Percentage showing how close your actual spending is to the target

An overall adherence score combines all three buckets into a single number. A score of 100% means your spending perfectly matches your plan. Scores above 100% in Needs or Wants mean you are overspending in that area.

Over/under indicators appear next to each bucket. A green indicator means you are within or under budget. A red indicator means you have exceeded the allocation.

Example Setup

Suppose your monthly take-home pay is $5,000 with the default 50/30/20 split:

Bucket	Percentage	Amount
Needs	50%	$2,500
Wants	30%	$1,500
Savings	20%	$1,000

Halfway through the month, you have spent $1,400 on Needs and $900 on Wants. Your Needs bucket shows 56% spent (on track), while your Wants bucket shows 60% spent (slightly ahead of pace). This gives you a clear signal to ease up on discretionary spending for the rest of the month.

Tips

If you are new to budgeting, start with the default 50/30/20 split for one or two months before adjusting. This gives you real data to work with when deciding whether to change the percentages.

Minimum debt payments belong in Needs. Extra payments above the minimum belong in Savings, since they are a choice that builds your financial health.

The three percentages must always add up to 100. If you increase one bucket, decrease another to compensate.
