Guarantor's Burden Calculator

The Guarantor's Burden Calculator estimates a general arithmetic estimate for your scenario from the quantities, rates, period, units and other assumptions requested on the page. Replace the example values with your own guarantors burden figures and recalculate after changing an assumption. Use it to compare scenarios, then verify any current rate or fee before acting.

Calculate the amount of debt that could be liable if the borrower fails to pay.

What a guarantor should know.

The guarantor in the loan agreement is legally bound under Section 680-701 of the P. P. A. The guarantor is liable for all debts if the borrower defaults. Before guaranteeing, the guarantor should verify the borrower's financial capacity, plan for the repayment and understand all the terms of the contract.

Frequently asked questions

What is the guarantor's responsibility?
The guarantor is liable for all the debt if the borrower fails to pay, including principal, interest, default interest and fees. The bank can sue the guarantor directly, and this debt will affect the guarantor's credit score.
Can you withdraw your bail?
The withdrawal of guarantees is difficult, requiring the bank's consent and the substitution of a guarantor or the borrower's proof of self-reliance, so careful consideration should be given before agreeing to guarantees.
Is it a guarantee that affects your own loan application?
Yes, banks will count secured debt as a financial burden on the guarantor, which may raise DTI and affect future personal loan approvals.
Disclaimer: The calculation is an estimate. The actual burden depends on the terms of the contract and the judgment.
