In-depth explanation
Estimate fixed monthly repayments for a personal loan or similar amortising debt. Enter the amount borrowed, interest rate, and term to see payment size and total interest paid. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
Payments use the standard amortising loan formula from principal, annual rate, and number of months. APR is not always the same as the interest rate — it can include fees. Use the APR Calculator when comparing the true cost of different offers.
The maths is similar, but the Mortgage Calculator is tailored for home loans with deposit and property price inputs. Use Loan Calculator for quick planning; confirm important money, tax, or health decisions with an official source or professional when needed.
