Short-Term Disability Calculator
STD insurance benefit.
Calculate short-term disability benefits by entering your weekly salary, benefit percentage, waiting period, and maximum benefit weeks.
What this tool does
This calculator estimates the total financial benefit available under a short-term disability insurance plan. It multiplies your weekly salary by the benefit percentage to find your weekly payment amount, then accounts for the waiting period and maximum benefit duration to arrive at a total payout figure. The result also shows your replacement rate—the percentage of your regular income the benefit represents. The waiting period (the gap before payments begin) and maximum benefit weeks are the inputs that most affect your final total. This tool is useful for modeling scenarios such as understanding how different waiting periods change your net benefit, or comparing plans with varying benefit percentages and durations. The calculation assumes consistent weekly income and doesn't account for taxes, offsets from other income sources, or plan-specific exclusions that may apply in your situation.

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. Adjusting one input at a time toward extreme values shows which ones move the result most.
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 result tells you
The calculation distils your inputs into a single figure. Its value is in seeing how that figure shifts as the inputs change.
What this doesn't capture
The result reflects only the inputs you provide and the assumptions built into the formula. It is a simplified model rather than a complete picture, and factors specific to your situation may matter just as much.
£1,000 × 60% × (26 - 1) = $15,000.00.
Inputs

Sources & Methodology
Methodology
The calculator computes short-term disability benefit by multiplying your weekly salary by the stated benefit percentage to determine the weekly payment amount. This weekly benefit is then multiplied by the difference between the maximum benefit weeks and the waiting period weeks to calculate total payable benefit. The model assumes a constant weekly salary throughout the benefit period, applies the benefit percentage uniformly, and treats the waiting period as a simple reduction in eligible claim weeks. It does not account for taxation, employer-specific policy variations, partial disability scenarios, benefit caps based on income thresholds, or changes to salary during the claim period.
