Budgeteen

Budgeting basics are the totals a plan is built from. In is money that arrived. Out is money that left. Left this week, cash on hand, and safe to spend answer three different questions, and they are not the same number. Named methods sit on top of these totals. Budgeteen keeps them on your phone.
This page names the totals a budget is made of. It is education, not a recommendation of an allocation, a product, or a provider. The dollar figures below are a worked example so the arithmetic is visible. They are not a typical allowance and not a target.
A teen week produces several totals at once. They answer different questions. Using one of them to answer a different question is the usual mix-up, before any named method starts.
| Total | The question it answers | What it leaves out |
|---|---|---|
| In | What arrived this week that you can hold? | Money you hope shows up later. |
| Out | What did you log as leaving? | A purchase you only planned. |
| Left this week | In minus Out for this week. | Cash still on the ledger from earlier weeks. |
| Cash on hand | What is still on the whole ledger? | Whether this week itself was ahead or behind. |
| Safe to spend | Cash on hand minus bills that are already late. | Left this week, and bills that are not late yet. |
The CFPB's monthly budget tool builds a budget the same way: list income, list expenses, subtract spending from income. In is income for the period: allowance you are holding, a gift in your hands, or gig pay you were handed. A Friday that has not happened yet is not In. A relative who said they might send money is not In. Logging hoped-for cash makes every later total describe a week you do not have. When a repeating payout misses, skip it. The allowance tracker for teens moves the next date and leaves the ledger unchanged.
Out is spending you record. A plan to buy lunch is not Out until the lunch is logged. A bill you added to a list is not Out until you mark it paid. Writing the plan down and writing the spend down are two steps. The first is the budget. The second is the record of what happened. A list of receipts with no plan is a diary. A plan with no record of Out cannot tell you whether you followed it.
Left this week is this week's In minus this week's Out. On the Budget screen that figure does not drop below zero. When Out is larger than In, left this week reads zero and the extra spending reduces cash on hand. Cash on hand is income minus spending across the whole ledger, so earlier weeks you did not spend still sit there until a later Out uses them. A quiet week can show left this week at zero while cash on hand is still the older stash. Those are different questions, not two labels for one pile.
Safe to spend starts from cash on hand and subtracts bills that are already late. It does not subtract every bill you might pay someday, and it does not copy left this week. A late phone top-up lowers safe to spend even when this week's In minus Out still looks fine. If nothing is late, safe to spend matches cash on hand, and the Budget screen does not repeat the same figure as a second row. Reading the number does not pay the bill and does not move money. Paying it, or skipping it, is a separate action. Safe to spend is also not advice about what to buy. It is the cash figure after overdue bills are acknowledged.
Ready to assign is separate from the five totals above. It is this week's logged In that does not have an envelope job yet. You can spend from cash and still have Ready to assign above zero, because spending is Out and assigning is the plan. You can also bring Ready to assign to zero while cash on hand is a different number, because the envelopes describe jobs for this week's In, not the older stash. If nothing arrived, there is nothing to assign. The screen says the plan is not cash.
How to fill Needs, Wants, Save, and Give, including a worked week beside the 50/30/20 teaching split, is on budgeting for beginners. When to use envelopes, zero-based budgeting, 50/30/20, pay yourself first, or a bill calendar is on budgeting strategies. The in-app loop for the four envelopes is on how teen budgeting works in Budgeteen. Which tool should hold those totals — a spreadsheet, a bank app, or a phone plan — is on best budgeting tools.
Worked example only. Suppose $10 was already on the ledger from earlier weeks. This week $30 of allowance is in your hands, and you log $12 of lunch as Out. No envelope jobs are filled yet. A $6 phone top-up is already late.
| Total | Amount | Arithmetic |
|---|---|---|
| In | $30 | Allowance you are holding. The earlier $10 is not this week's In. |
| Out | $12 | Lunch you logged. The late bill is not Out until you mark it paid. |
| Left this week | $18 | $30 minus $12. |
| Cash on hand | $28 | $10 plus $30 minus $12. |
| Safe to spend | $22 | $28 minus the $6 late bill. |
| Ready to assign | $30 | This week's In, because no envelope job is filled yet. |
Six amounts, one week. Left this week ($18) is not cash on hand ($28), which is not safe to spend ($22), which is not Ready to assign ($30). None of these lines tells you a percent to keep. Change the story and the arithmetic changes with it. Next week's In might be zero.
If nothing arrived and you log no Out, left this week is zero. Cash on hand can still be the earlier stash, and safe to spend is that cash minus any bill that is already late. Ready to assign stays empty: there is no In to give a job. Do not type the allowance that missed so the week looks normal. A learner with no income still has the skills roadmap and an empty plan. Earning is optional.
Budgeting basics are the totals underneath any method. In is money that arrived. Out is money that left. Left this week, cash on hand, and safe to spend answer different questions, so they are not interchangeable. Envelopes and percentage splits sit on top of these totals. The basics are not a bank login, a card, or a required percent.
Left this week is this period's income minus this period's spending. Cash on hand is everything still on the ledger, including money from earlier weeks. A week can show little left while older cash is still on hand. Mixing the two makes a plan look broken when the week and the stash are answering different questions.
Safe to spend is cash on hand minus bills that are already late. It is not left this week, and it is not a suggestion of what to buy. A late phone top-up lowers safe to spend even when this week's income minus spending still looks fine. Paying or skipping that bill is a separate step from reading the number.
No. Income is cash, allowance, or gig pay you log when you can hold it. Spending is what you record leaving. Left this week, cash on hand, and safe to spend are arithmetic on that log. Budgeteen keeps the log on your phone. No bank or debit card is required. Money you only expect is not income yet.
Then this week's In is zero. If you log no Out, left this week stays zero. Cash on hand can remain above zero from earlier weeks, and spending you still log reduces that cash instead of printing a negative week. Do not type an allowance that did not arrive. An empty week is a valid budget.
