Income Protection Calculator Australia
This income protection calculator estimates the monthly benefit a policy could pay and any extra cover you may need beyond existing policies and super.

What it does
The Income Protection Calculator works out the monthly benefit income protection would pay (up to a set percentage of income) and any additional cover you need beyond existing cover.
Data sources & parameters
This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.
We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
Monthly benefit = income × benefit% ÷ 12; additional needed = monthly benefit − existing cover
How it works
The monthly benefit is your income times the benefit percentage, divided by 12. Additional cover needed subtracts any existing monthly cover.
Where it is used
- Sizing income protection cover
- Checking if existing cover is enough
- Protecting against illness or injury
Worked example
On a A$90,000.00 income at a 70% benefit, income protection pays … a month (… a year); with no existing cover, … of extra cover is needed.
What the income protection calculator does
The income protection calculator helps you work out how much of your income could be replaced if illness or injury stopped you from working. It estimates the monthly benefit a policy would pay, based on a set percentage of your income, and then shows any additional cover you may need once your existing arrangements are taken into account.
For most working Australians, income is the single largest financial asset. A mortgage, a car, and everyday living costs all depend on a steady paycheque continuing. This tool gives you a clear, quick estimate so you can see whether your current safety net is adequate.
Why income protection matters
If you could not work for months due to a serious illness or injury, your regular expenses would not pause. Rent or mortgage repayments, utility bills, groceries, and loan repayments continue regardless. Income protection is designed to replace part of your earnings during that period, giving you time to recover without draining savings or falling behind.
The calculator turns an abstract worry into a concrete number. Instead of guessing, you see an estimated monthly benefit and a clearer picture of the gap between what you would receive and what you actually spend.
People sometimes assume that savings, sick leave, or a partner's income would cover a long absence from work. In practice, sick leave is usually measured in days rather than months, and savings can be exhausted faster than expected once regular income stops. Income protection is designed for the longer, more serious interruptions that other safety nets are not built to handle, which is exactly where the financial strain is greatest.
How the calculation works
The calculator uses a straightforward approach:
- It takes your income as the starting point.
- It applies the portion of income that a policy would typically replace.
- It subtracts any cover you already hold, such as a policy inside superannuation.
- The result is the additional monthly cover you may need.
Insurers generally cover a proportion of your pre-disability income rather than the full amount. This is intentional, since it keeps an incentive to return to work once you are able. The precise percentage varies between policies and providers, so the figure here is a planning guide rather than a quote.
What you need to enter
To get a useful estimate, have a few details ready:
- Your annual or monthly income before tax.
- Any income protection cover you already hold, including cover through super.
- The level of cover you would like to aim for, if you have a target in mind.
The more accurate your inputs, the more reliable the estimated monthly benefit and additional cover figure will be.
Reading your result
The result shows two useful numbers. The first is the estimated monthly benefit a policy could pay based on your income. The second is the additional cover you may need after accounting for what you already have in place.
If the additional cover figure is zero or small, your existing arrangements may already be close to adequate. If it is large, there is a meaningful gap between your income and the protection currently in place. Either way, the number gives you a starting point for a conversation with an adviser or insurer.
Existing cover through superannuation
Many Australians already hold some income protection automatically through their super fund. This is easy to overlook, yet it can significantly reduce the extra cover you need to arrange separately. Before taking out a new policy, it is worth checking your super statement to see what cover, waiting period, and benefit period apply.
Because default cover through super varies widely, the calculator lets you enter your existing cover so the additional amount reflects your real position rather than a generic assumption.
Things to keep in mind
A benefit calculation is only one part of choosing income protection. Several other factors shape how a policy performs when you claim:
- The waiting period before payments begin.
- The benefit period, or how long payments continue.
- Whether the policy defines disability by your own occupation or any occupation.
- Premium structure and how it may change over time.
These details determine the real-world value of a policy just as much as the headline benefit amount. A generous benefit paired with a long waiting period and a short benefit period may still leave you exposed during exactly the situation you were insuring against. Use the calculator to size the benefit, then review the policy wording carefully or speak with a licensed adviser before deciding.
It is also worth revisiting the sum periodically. As your income grows, your commitments increase, or your family situation changes, the level of cover that suited you a few years ago may no longer be enough. Treating the estimate as a living figure rather than a one-off exercise keeps your protection in step with your real needs.
When to use this tool
The income protection calculator is helpful in several situations:
- Starting a new job or receiving a significant pay rise, when the income you protect changes.
- Taking on a mortgage or other large financial commitment.
- Starting a family, when more people rely on your earnings.
- Reviewing existing cover to check it still matches your circumstances.
Running the numbers regularly keeps your protection aligned with your life rather than frozen at a level set years ago.
