Life is unpredictable. If you fall ill or get injured and can’t work, how would you manage financially?
Income protection insurance can help by replacing a portion of your salary if you’re unable to work due to sickness or injury. But how much cover is enough?
In this guide, we’ll explain in clear, simple terms how to decide the right amount of income protection cover for your situation, as well as touching on other protection insurance types like life insurance and critical illness cover.
Our goal is to help you make an informed choice to safeguard your income, protect your family, and support your long-term financial peace of mind.
What Is Income Protection Insurance?
Income protection insurance offers you a replacement income if you can’t work due to illness or injury.
Typically, this pays out around 50–70% of your salary until you can return to work or reach retirement age, depending on the policy terms.
Income protection is different from:
- Life insurance, which pays a lump sum if you die.
- Critical illness cover, which pays out if you’re diagnosed with a serious illness covered by the policy.
- Mortgage protection, which can help protect your mortgage payments if the unexpected happens.
Each type of protection insurance has a role in your financial safety net, but this guide focuses mainly on income protection cover.
Why Is Calculating the Right Cover Important?
Getting the right amount of income protection cover is crucial for two main reasons.
- Too little cover: You may not have enough money to cover your everyday bills and essential expenses.
- Too much cover: You might pay higher premiums unnecessarily.
The best income protection policy balances the cost with your genuine financial needs.
Your cover should be based on your income, your monthly outgoings, your debts, your family responsibilities, and any sick pay you may already receive from your employer.
How to Work Out How Much Income Protection Cover You Need
To work out how much income protection insurance you may need, start with your real monthly costs.
The aim is not always to replace your full salary. The aim is usually to make sure your essential financial commitments can still be managed if you are unable to work due to illness or injury.
1. Calculate Your Essential Monthly Expenses
Start by listing your essential monthly outgoings.
These may include:
- Mortgage or rent
- Utilities, including electricity, gas, and water
- Food and groceries
- Travel costs
- Insurance payments, such as home, car, and life insurance
- Council tax
- Childcare and school costs
- Minimum loan or credit repayments
For example, Sarah lives in Manchester and pays:
- £750 rent
- £150 utilities
- £300 food
- £150 transport
- £50 council tax
- £200 in other essentials
That totals £1,600 per month.
This gives Sarah a clear starting point when deciding how much income protection cover she may need.
2. Account for Income Replacement Percentage
Income protection policies normally replace around 50–70% of your gross income.
This is to encourage you to return to work if you can and to avoid replacing bonuses and overtime.
Let’s say Sarah earns £2,500 a month before tax.
At 60% replacement, her income protection payout would be:
- £2,500 x 60% = £1,500 per month
Since her essential expenses are £1,600, 60% of income is slightly short.
If Sarah’s policy covers 60%, she may need to increase the cover where possible or make sure she can reduce some expenses if she becomes unable to work.
3. Consider Your Other Sources of Income
When choosing income protection insurance in the UK, it is important to consider any other income you could receive if you can’t work.
This may include:
- Sick pay from your employer
- Savings or investments
- Benefits such as Employment and Support Allowance, also known as ESA
- Support from a partner or household income
If you get full sick pay for 3 months, you may need less cover during this period, but more after it ends.
For Sarah, her employer pays full sick pay for 3 months. She may want her income protection policy to start only after this period.
This affects the waiting period, also known as the deferred period, and can also affect the premium.
4. Factor In Debts and Special Expenses
Do you have debts with monthly repayments?
These may include:
- Credit cards
- Car finance
- Personal loans
- Overdrafts
- Buy-now-pay-later commitments
- Other regular credit repayments
These should be included when calculating your monthly expenses.
You should also consider one-off expenses that might arise if you fall ill or become injured.
These could include:
- Medical equipment
- Home adaptations
- Extra transport costs
- Additional childcare support
- Temporary help at home
Income protection cover is designed to help support your regular income, so understanding your full financial picture is important.
5. Think About Inflation and Future Needs
Living costs tend to rise over time.
Your rent, mortgage payments, utility bills, food costs, transport costs, and family expenses may all increase in the future.
Some income protection policies offer options to increase your cover each year to help keep pace with inflation.
This is often called inflation protection or an index-linked income protection policy.
It may increase the cost of the policy, but it can help your cover stay more relevant over time.
Real-Life Example: Tom’s Income Protection Needs
Tom is a graphic designer from Leeds earning £3,000 a month.
His monthly essentials total £1,800, including his mortgage, bills, and loan repayments.
Tom receives statutory sick pay for 28 weeks but no full sick pay from his employer.
Because Tom’s employer does not offer full sick pay, his income protection policy needs to consider when his income would reduce.
He selects 60% income replacement starting after the statutory sick pay period ends.
Tom calculates:
- Monthly income: £3,000
- 60% income replacement: £1,800
- Essential monthly expenses: £1,800
This means Tom’s cover aims to replace enough income to meet his essential monthly costs.
Tom’s insurer also offers an inflation-linked increase to help keep pace with future costs, which he chooses to include.
Considering Life Insurance and Critical Illness Cover
While income protection insurance covers ongoing living costs, life insurance and critical illness cover serve different purposes.
A strong protection insurance plan may include more than one type of cover.
- Life insurance can help your family pay off the mortgage or cover future education costs if you pass away.
- Critical illness cover provides a lump sum if you are diagnosed with certain serious illnesses covered by the policy.
- Income protection insurance can provide regular monthly income if you are unable to work due to illness or injury.
Many UK families choose a combination of these policies to protect their financial future.
The right mix depends on your income, family situation, mortgage, debts, savings, employment benefits, and long-term goals.
Tips for Choosing the Right Income Protection Policy
When choosing an income protection policy, it is important to look beyond the monthly premium.
You should consider:
- Waiting period: How long you wait before payments begin. A longer waiting period often means lower premiums but less immediate cover.
- Benefit period: How long payments could last. This may be until retirement, age 65, or for a shorter fixed period.
- Policy terms: What illnesses, injuries, and exclusions apply.
- Inflation protection: Whether you want your cover to increase over time.
- Premiums: How much the policy costs each month.
- Employer sick pay: Whether your workplace already provides short-term or long-term sick pay.
- Existing protection: Whether you already have life insurance, critical illness cover, or mortgage protection.
- Family needs: Whether dependants rely on your income.
The cheapest income protection policy is not always the most suitable.
The right policy should be affordable, realistic, and matched to your financial responsibilities.
