Loan Repayment Planner

Plan your home, car, or personal loan repayment schedule with EMI, interest-only, or linear amortization models. Add prepayments and see how they change your interest and tenure.

Loan inputs

Choose your loan structure, amount, tenure, and interest rate. You can also add one-time prepayments to see how they impact your interest and duration.

Prepayments (optional)
Add extra one-time principal payments on specific dates (max 50). These reduce your outstanding and future interest.

Understanding loan & prepayment types

Different countries and banks structure loans differently. This planner lets you simulate the three most common mathematical models used worldwide and how prepayments change your journey.

1. EMI / Amortizing loan (annuity)

Used in India, USA, Canada, UK, and most of Europe. Your monthly EMI is fixed throughout the tenure. Early EMIs are mostly interest; later EMIs are mostly principal.

With prepayments you can choose:

  • Reduce tenure (principal reduction / EMI fixed) – EMI stays the same, but the loan finishes earlier and your total interest drops sharply. This is the default and is what many banks offer if you don't ask to reduce EMI.
  • Reduce EMI (tenure roughly fixed) – after each prepayment the bank recalculates a lower EMI for the remaining tenure. Cash flow becomes lighter each month, but your overall interest saving is usually smaller than the tenure-reduction option.

2. Interest-only loan

Common in Sweden, Denmark, Netherlands, and sometimes UK and Australia. You pay only interest every month; principal does not reduce until the end or until you start an amortizing phase. Prepayments simply knock down the principal early and reduce future interest.

3. Linear amortization (constant principal)

Popular in Sweden, Denmark, Finland, and Japan. You pay the same principal every month, so your total payment is highest in the beginning and falls over time. Prepayments shorten the tail of the loan and reduce interest fairly evenly.

How to use this planner

  • Use it for any loan type: home, vehicle, education, or personal loan.
  • If you're in India, USA, UK, Canada or most of EU, your bank almost certainly uses the EMI / annuity model.
  • If you're in Sweden or Denmark, you may have a mix of interest-only and linear. You can simulate each phase separately here.
  • Use the prepayment section to model bonus payments, salary hikes, or lump-sum injections and see how much interest you could save and how many years you could shave off.
  • This tool is for educational and planning purposes only. Actual bank calculations may use different rounding rules, fees, or regulations.
