AI Prompts for Personal Finance: Budget, Debt Payoff and Net Worth

The net worth statement lists assets (what you own) and liabilities (what you owe); net worth is the difference. The cash-flow statement compares take-home pay with the money going out over the same months. Liquidity is the cash available within days.

• $270 a month short: Priya spent $270 more than her take-home pay every month, and the credit card covered the gap without her noticing.
• $400 of liquidity: her essential costs are $3,700 a month, about $123 a day. Her savings covered 3 days without income.
• $2,800 a year in interest: the card balance of $11,200 at 24.99% APR costs about $233 a month, more than her subscriptions and phone combined.

A spending analysis sorts every transaction into a category and compares the averages with what the person believed they spent. A recurring charge is a payment taken automatically each week, month or year.

• $350 guessed, $840 spent: small, frequent purchases are the ones people forget. Delivery orders under $30 made up most of the gap.
• 14 subscriptions, not 5: nine were charged to the credit card, where Priya rarely read the statement. Five had not been used in over 90 days.
• $1,152 a year: cancelling the five unused subscriptions saves $96 a month before any other change to her spending.

A zero-based budget allocates all take-home pay before the month starts, to costs, savings and debt payments, so income minus allocations equals zero. The 50/30/20 rule, popularised by Elizabeth Warren, is a benchmark: 50% to needs, 30% to wants, 20% to savings and extra debt payments.

• Wants cut from $2,867 to $950: eating out from $840 to $400, shopping from $1,160 to $180, fun from $580 to $179, and five subscriptions cancelled. Gifts and travel now come from sinking funds. Both large cuts are flagged, with the weekly check that keeps them realistic.
• 32% to savings and debt: above the 20% benchmark, and deliberately so while the card costs 24.99%. Needs at 54% are slightly above 50%, because rent is $2,050.
• $0 unallocated: in the spreadsheet, the cell turns green only when every dollar is allocated, and actual spending fills in from the transactions sheet.

An irregular expense is predictable in total but not in timing. A sinking fund saves for it every month, the annual cost divided by twelve, so the bill is paid from savings rather than on a credit card.

• $3,400 on the card: the transmission repair started the debt. A 2017 car with 104,000 miles was due major repairs; only the month was unknown.
• $4,780 a year: five categories of irregular costs came from her statements and calendar. Before this step, none of them had a budget line.
• $150 a month for the car: the next repair is paid from the car fund. The emergency fund stays for costs that could not be predicted.

An emergency fund is cash held for costs that cannot be predicted, sized in months of essential expenses: the costs that continue if income stops. It must be liquid: available within days, without penalty or risk of loss.

• $3,700 a month essential: rent, utilities, groceries, car, health and loan minimums continue if income stops. Eating out and subscriptions do not.
• Starter fund first: $2,000 comes before extra card payments, so the next surprise does not go back on a 24.99% card.
• $11,100 target: three months suits one income from a stable employer. The fund is completed after the card, when the card payment moves to savings.

A policy is judged on four terms: the premium (what you pay), the deductible (what you pay before the insurer pays), the coverage limit (the most it pays) and the exclusions. Liability cover pays if you are responsible for injury to someone or damage to their property.

• $96 a year of duplicate cover: her credit card already included roadside assistance, the same service her car policy charged $8 a month for.
• No liability cover: if a leak in her apartment damaged the unit below, she would pay for the repairs herself. Adding it costs about $10 a month.
• Deductible matched to savings: a $500 deductible only works if $500 is available in cash. The starter fund makes it payable.

The APR (annual percentage rate) is the yearly cost of borrowing. The avalanche method puts every extra dollar on the highest APR first, which costs least. The snowball method, described by Dave Ramsey, pays the smallest balance first, which clears accounts sooner.

• A minimum that barely moves: the card’s minimum is interest plus 1% of the balance. At $11,200, $233 of the first $345 minimum is interest.
• $120 between the methods: snowball clears the $900 phone loan in October but costs $120 more interest. Avalanche is recommended, and the spreadsheet switches between the two.
• $1,800 from December: when the starter emergency fund is reached, its $700 a month moves to the card. The card is cleared in May 2027.

Total cost of ownership (TCO) is every cost of an option over a set period, less what it is worth at the end. Depreciation is the fall in an asset’s value over time. Opportunity cost is what the same money could have done instead.

• $2,999 at signing: the monthly figure left out the amount due at signing and the higher insurance a leased car requires.
• $3,500 of depreciation: her 2017 car is worth about $9,000 now and about $5,500 in three years. That fall is a real cost of keeping it, and it is counted.
• $10,803, close to the card balance: the opportunity cost of the lease was almost the whole $11,200 card balance at 24.99%.

An employer match is money the employer adds when you contribute, up to a limit; vesting is how long you must stay to keep it. A 401(k) is a tax-advantaged account: contributions reduce taxable income. The savings rate is the share of gross income saved in a year.

• $2,360 a year: her employer matches 100% of contributions up to 4% of salary. At 2%, half the match went unclaimed. Her match vests after two years, which she passes in January.
• $145 of take-home, $393 invested: raising her contribution by $197 a month costs about $145 after tax, and the match adds another $197.
• Match before extra debt payments: the order in "protect before you grow" puts the full match ahead of anything except the starter fund, because it is an immediate 100% return.

An annual financial review compares actual results with the plan and explains every gap. Goals are written as SMART goals: specific, measurable, achievable, relevant and time-bound.

• $2,800 a year of interest gone: the card was cleared in May 2027, the month the September 2026 schedule set out.
• Money saved, not market luck: the $31,800 rise counts only money saved and debt repaid. Investment returns are reported separately.
• Next goal: three months of essential costs, $11,100, by October 2027, then a home deposit fund of $400 a month.
