How the calculation works

Understand the formula before relying on the result

Current calculated payment

The current balance, rate, remaining amortization, and selected frequency are used to reconstruct a comparable scheduled payment.

Renewal payment

The lump sum is applied first, then the entered renewal rate and amortization determine the new payment.

Term projection

Each scheduled payment is simulated through the selected renewal term to calculate interest, principal, and balance at the next maturity.

Keep-payment comparison

A second schedule holds the reconstructed current payment constant to measure extra principal and term interest savings.

Interpret the result

Payment shock is manageable when planned

The change can be converted into a monthly budget adjustment before the first renewal payment is due.

Extending amortization trades time for cash flow

A longer amortization can lower the payment while increasing the balance and total interest carried forward.

A renewal lump sum is powerful

Applying cash before recalculating the payment reduces principal immediately and can lower both payment and term interest.

Keeping a higher payment accelerates equity

When affordable and permitted, maintaining the old payment can reduce the balance faster after a lower-rate renewal.

Common mistakes

  • Accepting the first renewal offer without comparison.
  • Extending amortization without measuring long-run cost.
  • Ignoring switching, discharge, appraisal, or collateral-charge issues.
  • Waiting until maturity to provide documents.
  • Reducing payment after a rate drop instead of considering principal acceleration.

What lenders review

  • Updated income, credit, debts, and property if switching or refinancing.
  • Remaining amortization and requested new amortization.
  • Mortgage type, charge registration, portability, and discharge restrictions.
  • Payment history, taxes, insurance, and property condition.
  • Rate, term, prepayment privileges, penalties, and renewal features.

Planning tips

  • Begin comparing offers several months before maturity.
  • Separate a straight switch from a refinance with added funds or amortization.
  • Use a lump sum before renewal if liquidity remains adequate.
  • Compare balance at the next renewal, not only the new payment.
  • Review penalty and portability if a sale may occur during the next term.

Frequently asked questions

Questions about this calculation

Do I have to renew my mortgage?

Unless the balance is paid in full, the mortgage must be renewed, refinanced, switched, or otherwise repaid at maturity.

Can I change lenders at renewal?

Often yes, subject to qualification, property, documentation, legal registration, product, and timing requirements.

Can I extend amortization at renewal?

It may be possible through renewal or refinance, but lender policy and qualification apply and total interest can increase.

Is a lump sum allowed at renewal?

Many mortgages can be paid down at maturity without a prepayment penalty, but the contract and lender instructions should be confirmed.

Why might my lender statement payment differ?

Lenders may use specific rounding, exact dates, compounding, payment histories, skipped payments, or product rules not captured here.
