Income Protection vs Mortgage Protection

🛡️ Two Ways to Protect Your Income

Most household budgets depend on one or two incomes. If illness or injury stopped you working for months, the bills would not stop with your pay. Two types of insurance exist to bridge that gap, and they are easy to confuse: income protection and mortgage protection. They sound similar and overlap, but they cover different things, cost different amounts, and suit different people. Knowing the difference helps you buy the cover you actually need rather than paying for the wrong thing.

Key Point: Income protection pays you a regular benefit, typically up to around 75% of your income, if you cannot work due to illness or injury, and you can spend it on anything. Mortgage protection is narrower: it covers your mortgage repayments, or a set amount tied to them, if you cannot work. Income protection is broader and usually the more complete safety net, but it costs more. Mortgage protection is cheaper and simpler but only covers the home loan. The right choice depends on your budget, your other cover, and how much of your income you need to replace.

Income Protection

Income protection replaces a portion of your earnings, commonly up to about 75%, paid as a regular benefit while you are unable to work. It is designed to keep your whole household running, covering rent or mortgage, food, power and everything else, not just one bill. Because it is tied to your income, the bigger your earnings, the bigger the benefit it can provide.

Mortgage Protection

Mortgage protection, sometimes called mortgage repayment insurance, focuses on one thing: keeping a roof over your head by covering your mortgage repayments if you cannot work. The benefit is set around your repayments rather than your full income, so it is more limited, but it directly protects the single biggest commitment most families have.

Broad versus targeted: Income protection is the wide safety net for your whole income; mortgage protection is the targeted one for your home loan. Many people who can only afford one start with whichever matches their biggest worry, then broaden cover later.

CostGenerally higherGenerally lower

Wait Periods and Benefit Periods

Both types share two important settings that shape the cost and the cover.

  • Wait period (stand-down): How long you must be off work before payments start, often 4 weeks to several months. A longer wait means cheaper premiums but more time you must self-fund.
  • Benefit period: How long payments continue, perhaps two years, five years, or to a set age. A longer benefit period costs more but protects against a long-term inability to work.
You choose a wait period, say 8 weeks
You self-fund the first 8 weeks from savings
Then the benefit starts paying
It continues up to your chosen benefit period
Longer waits and shorter benefits lower the premium

Agreed Value vs Indemnity

Income protection can be agreed value, where the benefit is locked in when you take the policy, or indemnity, where it is based on your income at the time of claim. Agreed value gives certainty, useful if your income varies, while indemnity can be cheaper but may pay less if your income has dropped. Check which type a policy is.

🏥 ACC, Tax and Choosing

How ACC Fits In

New Zealand's ACC scheme covers accidents and injuries, paying weekly compensation if an accident stops you working. But ACC does not cover illness. A heart condition, cancer or a back problem from no specific accident would not be covered by ACC, and that is a major gap income protection fills. This is the key reason illness cover matters even though ACC exists.

The illness gap: Many people assume ACC has them covered, but it only covers accidents. Most long-term inability to work comes from illness, which ACC does not cover. Income protection covers illness as well as injury, closing that gap.

Watch for Offsets

Because income protection and ACC can both cover an injury, policies usually offset one against the other, so you are not paid twice for the same loss. Understand how your policy treats ACC payments, so you know what you would actually receive in different situations.

Choosing Between Them

  • If budget allows, income protection is usually the more complete cover, because it protects your whole income and covers illness, not just your mortgage.
  • If money is tight, mortgage protection can be a sensible, affordable start that protects your home, the thing you most fear losing.
  • Consider what else you have: existing life, trauma or disability cover, savings, and a partner's income all affect how much you need.
List your essential monthly costs, not just the mortgage
Check what ACC would and would not cover for you
Decide how much income you need to replace
Match that to income protection, or start with mortgage cover

✅ Common Mistakes and What to Do

Mistake 1: Assuming ACC Covers Everything

The trap: Skipping income protection because you think ACC has you covered.

Why it costs: ACC only covers accidents, not illness, and most long absences from work are due to illness. That leaves a big gap income protection fills.

Mistake 2: Only Insuring the Mortgage

The trap: Covering just the home loan and forgetting the rest of the budget.

Why it costs: Food, power, rates and other bills continue too. Mortgage protection is a good start but may not keep the whole household afloat.

Mistake 3: Ignoring the Wait Period

The trap: Choosing a short wait period without the savings to match, or a long one with no buffer.

Why it costs: A mismatch leaves you either paying more than needed, or unable to cover the gap before payments start. Align the wait period with your emergency savings.

Mistake 4: Not Checking Agreed vs Indemnity

The trap: Assuming the benefit is guaranteed when it is indemnity-based.

Why it costs: If your income fell before a claim, an indemnity policy may pay less than you expected. Know which type you hold, especially if your income varies.

A Simple Action Plan

1. Add up the income or costs you need to protect
2. Remember ACC covers accidents, not illness
3. Prefer income protection if you can afford it
4. Use mortgage protection as an affordable start if not
5. Set the wait period to match your savings buffer
6. Check agreed value vs indemnity and ACC offsets

Where to Go Next

Use the Income Protection Calculator for cover, the ACC Levies guide for how ACC works, and the Stepped vs Level Premiums guide for pricing.

Final word: Income protection replaces a share of your whole income and covers illness as well as injury, making it the broader safety net, while mortgage protection targets your home loan at a lower cost. ACC only covers accidents, so illness cover genuinely matters. Match the cover, wait period and benefit period to your budget and savings, and check the policy type.
