Equations & assumptions

Base schedule uses the contractual amortising payment. Extra monthly (and optional month-1 lump sum) are applied to principal after interest each month until the balance clears.

  • Capital-and-interest reducing balance; monthly rate = APR ÷ 12. Representative APR on UK credit ads may include fees — we model fees separately unless stated.
  • No early repayment charge modelled.
  • Extra payments assumed to reduce term (not reduce future contractual payment).

Notes & FAQs

Will my lender allow this?
Many personal loans allow overpayments; some charge early repayment fees. Check your agreement before sending extra money.
