Amortization Schedules with Multiple Tiers

A loan schedule can be divided into tiers, and each tier defines:

  • The type of payment (Interest Only, Fixed Payment, or Balloon).
  • The duration (number of payments and start date).
  • The payment amount, if applicable.
  • Any interest rate rules, such as fixed or variable with repricing logic.

The final tier always ensures that the loan’s outstanding balance, both principal and accrued interest, is fully recovered.

LendFoundry’s amortization framework supports all common repayment structures, individually or in combination.

1. Interest OnlyIn an Interest Only tier, the borrower pays only the interest accrued on the principal balance.

  • Payment Amount: Not predefined; the system automatically calculates the exact interest due.
  • Effect on Principal: The principal remains unchanged during this phase, while interest continues to accrue on the outstanding balance.
  • Flexibility: One or more consecutive tiers can be configured as interest-only, depending on repayment needs.
Schedule Amount

2. Fixed Payment (Principal + Interest)In a Fixed Payment tier, also referred to as equated monthly instalments (EMI), each repayment covers both principal and interest.

  • Payment Amount Configuration:
    • If a Fixed Payment tier is not the last tier, the payment amount must be explicitly defined.
    • Optional if it is the last tier, in which case the system calculates the exact amount required to bring the loan balance to zero.
  • Amortization Impact: The principal reduces progressively as each installment is paid, while interest is recalculated on the reducing balance.
Schedule Date

3. Balloon PaymentA Balloon Payment refers to a large lump-sum payment made at the end of the loan term. In tiered schedules, this is usually the final repayment.

  • Mechanism: When earlier tiers are configured as Interest-Only, the system ensures that the final tier adjusts the last payment to recover all remaining principal and any accrued interest.
  • Flexibility: Lenders can choose whether the balloon payment is the sole final installment or whether it follows a set of fixed installments.
Prinicipal

Loans with multi-tier schedules often involve different interest rate models across tiers. LendFoundry’s LSS supports both fixed and variable interest rates, with simple configuration.

  • Fixed Interest Rate: The same rate is applied throughout the tier, ensuring predictable repayment calculations.
  • Variable Interest Rate: The system only updates the rate at the beginning of a new tier, keeping it constant within the tier’s duration.
Schedule tier

  • Restructuring: Enables broader changes to the repayment plan, including redefining durations, amounts, or adding entirely new tiers.
  • Modifications: Allow updates to active or upcoming tiers, such as changing the number of payments, switching a tier from Interest Only to Fixed Payment, or adjusting the interest rate.

In both cases, accrued Interest to Recover (ITR) is automatically integrated into the updated schedule, ensuring lenders never lose track of accumulated interest. Lenders can choose whether to spread ITR across all payments, recover it upfront, or apply it at the end.

One of the biggest strengths of LendFoundry’s amortization engine is that it imposes no restrictions on tier combinations.

  • A loan can have all Interest Only tiers.
  • A loan can have all Fixed Payment tiers.
  • A loan can alternate between Interest Only, Fixed Payment, and Balloon phases.

This adaptability allows lenders to design virtually any repayment structure, from simple to highly complex, without manual intervention or external calculation.

For Lenders

  • Complete flexibility in structuring repayment schedules.
  • Support for diverse loan products and innovative repayment models.
  • Automated validation to ensure schedules always reconcile.
  • Clear audit trails for compliance and investor reporting.
  • Reduced manual intervention, saving servicing time and cost.

For Borrowers

  • Transparent repayment timelines.
  • Clear understanding of when repayment phases change.
  • Trust in accurate calculations, with no hidden amounts.
  • Flexibility to align repayments with financial capacity.

Yes, lenders can configure all tiers as Interest-Only or all as Fixed Payments if required.

No, but if tiers are Interest-Only, the system ensures the final payment covers the entire outstanding balance, effectively making it a balloon.

It automatically calculates the accrued interest based on the outstanding principal and recovers it as scheduled.

Yes. During modification or restructuring, new tiers can be introduced and recalculated instantly.

Borrowers see updated schedules in real time and are notified when a repayment phase changes.

Yes. Rate changes can be applied either at each schedule date or at the start of each tier.

The system enforces validations to confirm the final tier brings the balance to zero.

Yes, through Interest to Recover (ITR) options such as spreading it, collecting upfront, or at the end.

No. It applies universally across loan products where tiered repayment is needed.
