01 / THE BLUEPRINT
The problem to investigate
Borrowers may compare only the advertised periodic rate or size of the instalment, missing establishment fees, compulsory insurance, late charges and repayment frequency.
02 / THE BLUEPRINT
A possible solution
Create an education-only worksheet where a user enters publicly available contract terms and sees total scheduled repayment, all disclosed fees and a calendar of due dates. Show missing terms rather than guessing.
03 / THE BLUEPRINT
Start without an app
Use a paper example and a financial educator before building an app; independent professional advice may be needed for complex products.
04 / THE BLUEPRINT
Technology that could help
A local-only calculator can produce a clear cash-flow chart and compare scenarios. It should not connect to bank accounts, approve loans or assert regulatory compliance without a qualified local review.
05 / THE BLUEPRINT
Your first experiment
- Gather sample lawful lender terms and remove identifying borrower details.
- Ask a qualified local credit educator to verify formulae and disclosures.
- Test fictional offers with different tenors and fee structures.
- Explain cases where fees or variable rates make comparison uncertain.
06 / THE BLUEPRINT
People, resources and cost drivers
Needs financial-maths review, localisation of currency and legal terminology, plus plain-language design. Avoid collecting application credentials or bank statements.
07 / THE BLUEPRINT
What to validate — and when to stop
Compare calculations against the lender's provided repayment schedule and independent arithmetic. Stop if a misleading comparison arises from omitted charges.
08 / HYPOTHESIS TO TEST
Potential impact and how to measure it
Measure whether users correctly identify the more expensive offer and understand default consequences. Do not claim that understanding guarantees safe borrowing.
09 / THE BLUEPRINT
Risks and safeguards
Wrong calculations may lead to debt harm. State assumptions clearly, label variable rates, never recommend evading a debt or promise lending approvals.
10 / THE BLUEPRINT
Who might pay or maintain it
A consumer-education organisation can publish transparent formulas free of lender influence. Sponsorship must be disclosed and should not rank providers unfairly.
