This calculator uses a standard amortisation formula, which is the method most lenders use to calculate loan repayments. Each repayment covers:

  • A portion of the loan principal
  • A portion of the interest

At the start of the loan, a larger share of each payment goes toward interest. Over time, larger payments reduce the principal balance.

The calculator automatically adjusts results based on:

  • Loan amount
  • Annual Percentage Rate (APR)
  • Loan term (years or months)
  • Repayment frequency (monthly, weekly, or fortnightly)
  • Optional one-time fees added to the loan balance

With this loan calculator, you can instantly find:

  • Your repayment amount per month, week, or fortnight
  • Total interest paid over the full loan term
  • Total amount repaid, including interest and fees
  • A full amortisation schedule showing each repayment breakdown

This makes it easy to compare different loan offers or see how changing the interest rate or term affects your repayments.

For example, if you borrow £11,000 over 5 years at 6% APR with monthly repayments:

  • Monthly payment: approximately £212.66
  • Total interest paid: approximately £1,759.65
  • Total amount repaid: approximately £12,759.65

Exact figures may vary slightly depending on rounding and lender-specific calculations.

Using a loan repayment calculator helps you:

  • Budget more accurately
  • Avoid borrowing more than you can afford
  • Compare loan offers from different lenders
  • Understand the true cost of interest over time
  • Decide whether a shorter loan term could save money

It is especially useful before applying for credit, as it gives you a realistic expectation of ongoing repayments.

An amortised loan is repaid through regular, fixed payments over a set period of time. Each payment includes both interest and principal, ensuring the loan balance is paid in full by the end of the term.

The most common loan types are amortised, including:

  • Personal loans
  • Car loans
  • Mortgages
  • Business loans
