Short-term disability (STD) insurance pays a portion of salary (typically 60%) for 13-26 weeks if you can't work due to illness or injury. Available via employer benefits or private purchase. Much cheaper than long-term disability but covers shorter period - bridges to long-term cover or recovery.

1,000 weekly salary × 60% benefit × 25 weeks (26 max - 1 waiting) = 15,000 total benefit. Income replacement at 60% leaves 40% gap to cover from savings or partner income. Most employer-sponsored STD costs 20-60/month. Private STD: 50-150/month for similar coverage.

STD vs LTD: STD covers weeks (1-26 typically), LTD covers years (until age 65 commonly). Most need both. STD bridges the gap before LTD kicks in (LTD has waiting period 90-180 days). Without STD, that gap must be filled from emergency savings - often 3-6 months of expenses.

Quick example

With weekly salary of 1,000 and benefit of 60% (plus max benefit weeks of 26 and waiting period of 1), the result is 15,000.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Weekly Salary, Benefit %, Max Benefit Weeks, and Waiting Period (weeks). Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

What's happening under the hood

Weekly benefit = salary × benefit %. Total benefit = weekly × (max weeks - waiting period). The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

What the score tells you

Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

£1,000 £ × 60% × (26 - 1) = $15,000.00.

Inputs

Weekly Salary:1,000 £
Benefit %:60
Max Benefit Weeks:26
Waiting Period (weeks):1
Expected Result$15,000.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Methodology

Weekly benefit = salary × benefit %. Total benefit = weekly × (max weeks - waiting period).

Frequently Asked Questions

STD vs sick pay?
Statutory Sick Pay (SSP): 116/week, max 28 weeks - very limited. Employer sick pay: varies, often full pay 4-12 weeks then SSP. STD insurance: 60-67% of salary for 13-26 weeks - much more substantial. Most professionals need STD beyond statutory minimum.
Why 60% benefit?
Insurers cap below 100% to maintain incentive to recover and return to work. 60-67% replacement is high enough to cover essentials but low enough to motivate recovery. Some policies offer higher (up to 80%) at premium price.
Pre-existing conditions?
Most STD policies exclude pre-existing conditions for first 6-12 months. After exclusion period: full coverage. Group employer STD often has shorter or no pre-existing exclusion. Disclose all conditions when applying - non-disclosure voids policy.
STD vs LTD priority?
Both ideally. STD covers weeks 1-26. LTD covers months 4-12 onwards (often until retirement). Combined: continuous coverage from week 2 to retirement. Without STD: 3-6 month gap filled from savings. Without LTD: catastrophic gap if disability lasts beyond 6 months.
