How this estimate works
Your current loan is rebuilt month by month. Prepayments are applied after that month's EMI, then either the same EMI shortens the loan or, after a one-time prepayment, a new EMI is calculated over the original remaining months.
Formula
- Each month: balance = balance × (1 + r) − EMI − extra − one-time
- Reduce-EMI: new EMI = EMI formula on remaining balance and months
- Net saving = baseline interest − revised interest − prepayment fees
Limitations
- Rate changes during the loan are not modelled.
- Lenders may apply prepayments on specific dates or with conditions.
- Prepayment fees are only what you enter.
Data used
No official dataset is used. Every rate, price and premium is entered by you or is a labelled, editable assumption.
