Wage and Hour Calculator

Unpaid wages from misclassification or overtime violations.

About this calculator

This calculator applies the Fair Labor Standards Act's core overtime rule (29 U.S.C. § 207), the 40-hour workweek standard Congress set in 1940 — time-and-a-half pay for every hour worked beyond 40 in a week — to figure out what you were actually owed versus what you were paid, assuming you were paid straight time for all hours including overtime (the classic misclassification or off-the-books overtime scenario). It splits your weekly hours into regular hours (capped at 40) and overtime hours (anything above 40), prices the overtime hours at 1.5x your hourly rate, and compares that "should have been paid" total against what a straight-time calculation would have produced at your actual hours; the difference is the weekly underpayment, which by construction equals 0.5x your rate times every overtime hour — the "half" that straight-time pay misses. That weekly gap is then multiplied by however many weeks you specify, up to a lookback cap the calculator enforces itself: 104 weeks (2 years) for ordinary violations, extended to 156 weeks (3 years) if you mark the violation willful, matching the FLSA's actual statute-of-limitations structure.

Willful violations also trigger liquidated damages equal to the full back-pay amount — effectively doubling recovery — which is the real FLSA remedy for employers who knowingly or recklessly violated the law, not a made-up multiplier. The tool also nets out an estimated 33% contingency attorney fee, typical for wage-and-hour cases, to show what you'd likely keep. One thing to watch: this model assumes a flat hourly rate paid for all hours with zero overtime premium; it doesn't handle the fluctuating workweek method, salaried-exempt employees converting to an hourly equivalent, or state laws stricter than the federal floor (several states require overtime after 8 hours in a day, not just 40 in a week) — those need a different calculation.

How to Use This Calculator
  1. Enter Hourly Pay Rate and Hours Worked per Week including all overtime hours.
  2. Set Weeks of Unpaid Overtime — you can recover up to 2 years back (3 years for willful violations).
  3. Indicate Willful Violation — employers who knowingly violate FLSA owe double damages (liquidated damages).
  4. Review Total Recovery: back pay plus liquidated damages.
  5. Check Weekly Underpayment — the overtime premium owed per week (0.5x your regular rate for each hour over 40).
  6. Contact the Department of Labor or an employment attorney before the 2-year statute of limitations expires.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Hourly pay rate ($) = 15, Hours worked per week = 50, Weeks of unpaid overtime = 52, Willful violation? (0=No, 1=Yes) = 0 = 4 input(s) provided
  2. Calculate Total potential recovery
    Total potential recovery = adjustedBackPay + adjustedLiquidated
    3900 = $3,900
  3. Calculate Weekly underpayment
    Weekly underpayment = weeklyOwed - weeklyPaidActual
    75 = $75
  4. Calculate Total back pay
    Total back pay = weeklyUnderpayment * effectiveWeeks
    3900 = $3,900

Frequently Asked Questions

Why is the weekly underpayment exactly half my hourly rate times overtime hours?

The calculator compares what you should have been paid (regular hours at your normal rate plus overtime hours at 1.5x) against what a straight-time calculation would produce for the same total hours (all hours at your normal rate). Since you were paid 1x for overtime hours instead of the required 1.5x, the gap per overtime hour is exactly 0.5x your rate — that's the FLSA overtime premium the calculator is isolating, not the full overtime rate itself.

Why does marking the violation willful change my lookback period from 2 years to 3?

The FLSA's statute of limitations is genuinely 2 years for ordinary violations and 3 years for willful ones (where the employer knew or recklessly disregarded the law), and the calculator hardcodes this distinction: maxLookbackWeeks becomes 104 for non-willful and 156 for willful, then caps whatever weeksUnpaid you enter at that ceiling. So entering more weeks than the applicable cap doesn't increase your recovery — effectiveWeeks stops at the legal limit.

How do liquidated damages get added on top of back pay?

When willfulViolation is set to 1, the calculator sets liquidated damages equal to the full back-pay amount (adjustedLiquidated = adjustedBackPay), and totalRecovery adds that liquidated amount to back pay — effectively doubling your recovery. This mirrors the FLSA's actual liquidated-damages remedy, which exists specifically to penalize employers for willful violations rather than just requiring the wages that were originally owed.

Does this calculator handle salaried employees or state overtime laws stricter than federal law?

No — it assumes a flat hourly rate paid for all hours worked, with no overtime premium applied to any of them, which models the classic misclassification or off-the-books scenario. It doesn't handle the fluctuating workweek method, converting a salaried-exempt employee's pay to an hourly equivalent, or state rules that require overtime after 8 hours in a single day rather than 40 in a week — several states have that stricter daily-overtime standard, and this tool only applies the federal 40-hour weekly threshold.
