Rate Drops vs Rate Rises: Should You Refix, Stay Variable or Split?

Introduction

Interest rates fluctuate constantly, and your loan structure choice can significantly impact repayments and equity. This guide helps borrowers decide whether to stay variable, fix, or split their mortgage. Understanding the implications of rate drops and rises can save you money and protect your investment.

Take our mini self-assessment quiz to find out which loan type suits you best.

Understanding Fixed, Variable, and Split Loans

Here’s how to pick the right loan type based on your risk appetite and financial goals:

• Fixed Rate Loans: Predictable repayments for a set period (1–5 years). Pros: stable budgeting; Cons: less flexibility, potential break fees.
• Variable Rate Loans: Interest changes with market rates. Pros: flexibility, potential savings if rates drop; Cons: repayment unpredictability if rates rise.
• Split Loans: Combines fixed and variable portions. Pros: balances risk and flexibility; Cons: more complex to manage.

How Rate Drops Affect Your Loan Structure

Variable loans benefit immediately when rates drop, while fixed loans do not until the term ends. Example: For a $400,000 principal + interest loan, a 1% drop in variable rates reduces repayments by approximately $318/month. Split loans save proportionally based on the variable portion.

How Rate Rises Affect Your Loan Structure

Rising rates increase repayments for variable portions, while fixed loans remain protected. Using the same $400,000 example, a 1% rate rise adds roughly $318/month on the variable portion. Split loans partially absorb rate increases based on allocation.

Choosing the Right Structure for Your Situation

Here’s how to pick the right loan type based on your financial goals and risk tolerance:

• High risk tolerance → variable or split
• Low risk tolerance → fixed or split
• Moderate risk tolerance → split loan balances protection and flexibility

Repayment Strategy Tips & Equity Considerations

• Pay high-interest portions first.
• Maintain repayment buffers for unexpected rate rises.
• Monitor LVR to avoid mortgage insurance and preserve borrowing capacity.
• Use repayment calculators to model scenarios for fixed, variable, and split loans over 5 years.

Avoid These Common Mistakes

• Switching too frequently without accounting for break fees.
• Ignoring how rate changes affect split portions.
• Overestimating borrowing capacity during refinancing.
• Neglecting long-term equity impact when adjusting repayments.
