Fixed vs Floating Home Loan Rates: Pros, Cons & How They Affect You

Choosing the right home loan is one of the most important financial decisions you’ll make. In New Zealand, borrowers usually choose between fixed and floating (variable) home loan rates—or a mix of both. Each option has its own benefits and risks, and the right choice depends on your financial situation, goals, and appetite for certainty.

In this guide, we break down fixed vs floating home loan rates, their pros and cons, and how they can affect your repayments over time.

What Is a Fixed Home Loan Rate?

A fixed home loan rate means your interest rate stays the same for a set period—commonly 6 months, 1 year, 2 years, or longer. During this time, your repayments remain predictable, regardless of market changes.

Pros of Fixed Home Loan Rates

• Certainty and stability – Your repayments won’t change during the fixed term
• Easier budgeting – Ideal for households with fixed incomes
• Protection from rate rises – You’re shielded if interest rates increase
• Peace of mind – Great for first home buyers who want predictability

Cons of Fixed Home Loan Rates

• Limited flexibility – Extra repayments may incur break fees
• Missed savings if rates drop – You won’t benefit from lower rates
• Break costs apply – Refinancing early can be expensive

Fixed rates are popular with first home buyers who want certainty, especially when interest rates are expected to rise.

What Is a Floating (Variable) Home Loan Rate?

A floating home loan rate can move up or down depending on market conditions and changes to the Official Cash Rate (OCR). Your repayments may change over time.

Pros of Floating Home Loan Rates

• Flexibility – Make extra repayments anytime without penalties
• Benefit from rate drops – Your interest rate reduces if market rates fall
• Easier refinancing – No fixed-term break fees
• Faster loan repayment – Ideal if you plan to pay off your mortgage sooner

Cons of Floating Home Loan Rates

• Less certainty – Repayments can increase unexpectedly
• Harder to budget – Changes in rates may impact cash flow
• Higher starting rates – Floating rates are often higher than fixed rates initially

Floating loans suit borrowers with strong cash flow or those expecting interest rates to fall.

Fixed vs Floating: How Do They Affect You?

The impact of your loan type depends on your lifestyle and financial goals:

• First home buyers often prefer fixed rates for stability
• Investors may choose floating loans for flexibility and tax planning
• Families on tight budgets usually value predictable repayments
• Borrowers planning lump-sum payments benefit from floating loans

Many Kiwis choose a split loan strategy, fixing part of their mortgage while keeping the rest floating. This provides a balance of certainty and flexibility.

Which Home Loan Option Is Right for You?

Ask yourself:

• Can I handle repayment increases if rates rise?
• Do I want certainty or flexibility?
• Am I planning to make extra repayments?
• What is my long-term financial plan?

There’s no one-size-fits-all answer. The right choice depends on your income, risk tolerance, and future plans.
