AI Prompt to Compare Which Loan Types Fit What You Plan to Borrow For

What you need

Start with the borrowing need. The prompt has four lines to fill in:

• Purpose of the loan: [what the money is for]
• Amount needed: [amount and currency]
• Preferred repayment period: [months or years]
• Affordable monthly payment: [amount]

Be specific about the purpose. "A used car I plan to keep for six years" gets a better answer than "a car", because the model compares the loan's term with how long the thing you buy will last. If the money is for a business, a course or work on your home, say so, since each of these opens different loan types.

The snapshot template below is optional for this prompt. Without it, the model compares loan types in general terms for the amount you name. With it, the model can also see what you already owe, what you own that a lender might accept as security, and how the new payment would sit next to your current ones. If you paste it, fill in monthly income after tax and list your existing debts with their rates.

Leave out anything that identifies you, such as names or account numbers. The comparison works without them.

Here is my financial snapshot. Use only these numbers.

Currency: [e.g. EUR]
Date: [today's date]
Age: [optional]

ASSETS
[name] — [category: cash / stocks / ETFs / crypto / property / metals / other] — [value]
[name] — [category] — [value]
...

LIABILITIES
[name] — [type: mortgage / car loan / credit card / student loan / other] — [outstanding balance] — [interest rate if known]
...

CONTEXT (optional but improves the answer)
Monthly income after tax: [amount]
Monthly spending: [amount]
Amount I add to savings or investments each month: [amount]
Value of the same assets 12 months ago: [amount]

The prompt

Copy this exact text and paste it into ChatGPT, Claude or Gemini directly beneath your snapshot block.

You are a financial educator who explains borrowing options in plain language.
I am weighing a loan for the need below. If my snapshot is above, use only its
figures for what I already own and owe.

Purpose of the loan: [what the money is for]
Amount needed: [amount and currency]
Preferred repayment period: [months or years]
Affordable monthly payment: [amount]

1. List the loan types that could cover this need, such as a personal loan, car
   loan, student loan, credit card, home equity line of credit or business loan,
   and say which do not fit and why.
2. For each type that fits, explain how it works: secured or unsecured, fixed or
   variable rate, typical term, and what the lender can do if I stop paying.
3. Using two or three example rates that you label as illustrations, show the
   monthly payment and total interest for each type over its typical term.
4. Compare each loan term with how long the thing I am paying for will last.
5. If my snapshot is above, show how the new payment would change my monthly
   repayments as a share of my income.
6. List the questions to ask any lender and the costs besides interest to check.

If something you need is missing, ask me for it instead of estimating. Name no
lenders or products and do not tell me which loan to take. Say where rules or
typical rates depend on my country.

What good output looks like

A good answer first narrows the field. For a used car, it might keep the car loan, the unsecured personal loan and a home equity line, and set aside a student loan or business loan with one sentence each on why.

The cost comparison should use labelled example rates and show the working, because the term changes the result as much as the rate. Say you need 200,000 CZK. Over four years at an example 7%, the payment is about 4,789 CZK a month and the interest about 29,900 CZK. At 11% over the same four years, it is about 5,169 CZK a month and 48,100 CZK of interest. A home equity line at 5% over 15 years has the lowest payment, about 1,582 CZK, and the most interest, about 84,700 CZK. It also puts your home up as security for a car that may be gone long before the loan.

That last point is what the term check is for. A good answer says plainly when a loan would outlive the thing it paid for.

If you pasted the snapshot, the model should add the new payment to your existing ones: repayments of 12,600 CZK on a 70,000 CZK income are 18%, and adding 4,789 CZK takes them to about 25%. The closing questions should cover the APR or its local equivalent, arrangement and early repayment fees, and what happens after a missed payment.

What this can't tell you

The rates in the answer are illustrations. What a lender offers you depends on your income, credit record, the security you put up and the market at the time, and the model knows none of these.

The loan types on offer, what they are called and how they are regulated differ by country. Home equity lines of credit are common in some countries and rare in others, and protections for borrowers who fall behind vary as well. The model cannot judge whether you should borrow at all; it compares options for a need you have already decided on. It also cannot see the fine print of any offer. Rework the payment figures with a loan calculator before you rely on them.

Doing this without the retyping

In Sumio this prompt is "Loan Types and Product Selection", one of the 62 built into the app. It runs on your total liabilities, so the comparison starts from the debts you already track there, without a snapshot to fill in. Your records are stored on your device. Running the prompt sends the figures it needs to an AI provider, which writes the answer you then read in the app. The AI assistant is part of Sumio Premium.
