How to Use This Calculator

Coverage Needed tab

Enter your annual gross salary, monthly essential outgoings (mortgage/rent, bills, food, debt repayments), and your employer sick pay terms (weeks at full pay and half pay). Add your available savings. The calculator walks through each phase of income loss — employer sick pay, SSP at £118.75/week, then ESA/UC or nothing — and shows the monthly shortfall at each stage. It recommends a benefit amount based on your expenses and the 50-70% of gross income range.

Cost Estimate tab

Enter your age, occupation type (class 1-4), desired monthly benefit, deferred period (4-52 weeks), and policy term. The calculator shows an estimated monthly premium range, annual cost, cost as a percentage of salary, the benefit-to-premium ratio, and the breakeven point (how many months of claiming it takes to recover all premiums paid). Compare premiums across all five deferral periods at a glance.

Sick Pay Timeline tab

Enter your monthly take-home pay, employer sick pay terms, and savings. The calculator builds a 24-month timeline table showing exactly what happens to your income each month: from salary, to employer sick pay, to SSP, to ESA/Universal Credit. Each row shows the income source, monthly income, monthly shortfall, and cumulative shortfall. See when your savings run out and how the gap grows over time.

The Formula

Income protection replaces your income if you cannot work due to illness or injury:

Typical IP cover = 50-70% of gross annual salary ÷ 12

SSP (2025/26) = £118.75/week for up to 28 weeks (from day 4)
SSP monthly equivalent = £118.75 × 52 ÷ 12 = ~£515/month

Monthly shortfall = Essential outgoings − income while sick

After SSP ends (week 28+):
UC standard allowance = £393.45/month (single 25+)
UC couple allowance = £550.67/month

Income timeline when off sick:
Phase 1: Employer full pay (varies by contract)
Phase 2: Employer half pay (varies by contract)
Phase 3: SSP only — £118.75/week for remaining weeks (max 28 total)
Phase 4: ESA/Universal Credit or nothing

IP payouts from a personal policy are tax-free. This means 50-70% of gross income approximates your normal net take-home pay. If your employer pays for the policy, payouts are taxable as a benefit in kind.

The deferred period (waiting period) is how long you must be off work before the policy starts paying. Common options are 4, 8, 13, 26, or 52 weeks. Longer deferral = lower premium. Match your deferral to your employer sick pay + savings buffer.

Occupation classes affect premium cost: Class 1 (office/professional) is cheapest; Class 2 (light manual); Class 3 (skilled manual); Class 4 (heavy manual) is most expensive.

Example

Sarah — Project Manager, £40,000/year

Sarah earns £40,000 gross (~£2,600/month take-home). Her employer pays 4 weeks full sick pay then 4 weeks half pay. Her essential monthly outgoings are £2,200 (mortgage, bills, food, car). She has £6,000 in savings. Her partner earns £1,800/month.

What happens when Sarah cannot work

Weeks 1-4: Full pay~£2,600/month (take-home)
Weeks 5-8: Half pay~£1,300/month
Weeks 9-28: SSP only~£515/month
After week 28: UC~£394/month

The income gap

Essential outgoings£2,200/month
Shortfall on SSP (with partner)£0 (partner covers gap)
Shortfall on SSP (without partner)£1,685/month
Shortfall after SSP (without partner)£1,806/month
Cumulative shortfall at 12 months~£14,000

With income protection

Sarah takes out IP for £1,700/month (roughly 50% of gross, close to her net pay) with a 13-week deferred period. Her employer sick pay and savings cover the first 13 weeks. After that, IP pays £1,700/month tax-free until she recovers. Estimated premium: ~£35-50/month for an office worker aged 35. That is about 1% of her salary for complete income protection.

Without IP, Sarah would exhaust her savings by month 5 and face a growing cumulative shortfall. With IP, her income is replaced from week 13 onwards.

FAQ

Income protection (IP) insurance pays a regular monthly income if you cannot work due to illness or injury. Unlike critical illness cover (which pays a one-off lump sum for specific conditions), IP pays for any condition that prevents you from working, including back pain, mental health conditions, and musculoskeletal problems — which are the most common reasons for long-term absence. IP policies are FCA-regulated and typically pay until you recover, reach retirement age, or the policy term ends.
Most insurers allow you to cover 50-70% of your gross income. This approximates your net take-home pay because IP payouts from personal policies are tax-free. To calculate your cover amount: list your essential monthly outgoings (mortgage/rent, bills, food, transport, debt repayments) and aim to cover at least that amount. The maximum most insurers will offer is around 65% of gross income minus any state benefits you would receive.
The deferred period (also called the waiting period) is how long you must be unable to work before the policy starts paying. Common options: 4 weeks (most expensive, quickest payout), 8 weeks, 13 weeks (most popular, good balance of cost and coverage), 26 weeks (cheaper, aligns with SSP ending at 28 weeks), and 52 weeks (cheapest premium). Match your deferred period to your financial buffer: employer sick pay plus savings. A longer deferral significantly reduces your premium.
If you pay for the policy yourself (a personal policy), the payouts are completely tax-free. This is why 50-70% of gross income is sufficient — it approximates your normal net pay. If your employer pays for the policy, payouts are treated as earnings and are subject to income tax and National Insurance. Premiums for personal IP policies do not qualify for tax relief. Source: HMRC, FCA.
After 28 weeks, your employer stops paying SSP and gives you form SSP1. You can then apply for: New-style ESA (Employment and Support Allowance) if you have enough NI contributions; Universal Credit (standard allowance £393.45/month single 25+, plus up to £416.19/month LCWRA element if you have limited capability for work); or PIP (Personal Independence Payment) if you have a long-term condition (£72.65 to £108.55/week, not means-tested). Without income protection, your income drops dramatically after SSP ends.
