About this product
Read the full description
A flat rate is charged on the original amount for the whole term, even though you pay the loan down every month, so 4% flat is not the same price as 4% reducing. Buyers compare a flat quote from one dealer with a reducing quote from another and pick the wrong one. This app solves the real rate and puts the offers side by side.
What is inside
- A flat quote converter: instalment, total interest, nominal and effective annual rate, and the equivalent reducing rate.
- Fees as a fixed amount or a percentage, added to the loan or deducted from what you receive; insurance financed; a balloon payment; payments in advance or arrears.
- A reducing-rate quote for comparison, with its equivalent flat rate and total cost of credit.
- A Compare offers tab that ranks several quotes on the same price by effective annual rate.
- Early settlement three ways: the actuarial balance, the Rule of 78 and your own rebate percentage, with an optional settlement fee.
- A month-by-month schedule that exports to CSV, a printable A4 page for each tab, example data and a README with a worked example.
What is fact and what is a setting This is arithmetic. It states no UAE lending rule and no regulator limit. Fees, insurance, balloon and the settlement method come from your contract, so they are inputs. No bank or finance company is named.
What it is NOT It is a calculation, not a quote or financial advice. Variable rates, grace periods, skipped payments, late fees and tax on fees are not modelled.
How it differs from the UAE SME Bank Loan Application Pack That pack includes a repayment and flat-rate converter as one sheet among many application documents. This app is the full calculator: effective rate, comparison of offers, balloon, fees and early settlement.
How it was checked Instalments, effective rates, schedules and settlement figures were compared with an independent Python calculation over random cases, with the differences reported in the README. Typed screens, CSV, exports, reload, print view and phone width were tested in Chromium. Not tested in Safari, Firefox or Edge. Single use.
