Question 1

What is the 50/30/20 budgeting rule?

Accepted Answer

The 50/30/20 rule divides your after-tax income into three buckets: 50% for needs (rent, utilities, groceries, transport), 30% for wants (dining, entertainment, subscriptions), and 20% for savings and debt repayment. It's a simple starting framework — most personal finance experts recommend refining it to match your actual cost of living.

Question 2

How do I calculate my monthly budget?

Accepted Answer

Start with your monthly take-home income (after taxes). List every fixed expense (rent, utilities, loan payments) and every variable expense (groceries, dining, entertainment). Subtract total expenses from income. If the result is positive, you have surplus to allocate to savings or debt payoff. If negative, you need to cut spending or increase income.

Question 3

What should my monthly savings rate be?

Accepted Answer

Most financial planners recommend saving at least 20% of take-home income, with 10% going to retirement and 10% to other goals (emergency fund, down payment, etc.). If 20% isn't possible immediately, start with whatever you can manage and increase by 1% every few months.

Question 4

How can I track my budget without an app?

Accepted Answer

BudgeFlow lets you track every expense by sending a text message. No app to download — just text each purchase to your BudgeFlow number. The AI categorizes it, deducts from your envelope budget, and replies with your remaining balance. It's the lowest-friction way to keep a budget accurate in real time.

Question 5

What's the difference between a budget and an expense tracker?

Accepted Answer

A budget is a plan — you allocate amounts to categories before spending. An expense tracker is a record — it captures what you actually spent. You need both: the budget sets the limits, the tracker tells you whether you're hitting them. BudgeFlow combines both into a single SMS workflow.

Question 6

How often should I review my budget?

Accepted Answer

A weekly 5-minute check-in is the most effective cadence for most people. You're close enough to catch issues before they compound, but not so frequent that it becomes tedious. A full monthly review (comparing plan vs. actual) takes about 15 minutes and should happen before you set next month's amounts.
