Reasonable

The calculated daily rate falls within or near industry benchmarks, suggesting it represents a reasonable pre-estimate of delay damages.

This liquidated damages calculator helps owners and contractors build a defensible daily LD rate by summing the genuine daily costs of a project delay across categories such as lost rental income, extended supervision, financing, administration, and loss of use. It multiplies the daily rate by the delay duration for total exposure, then benchmarks the rate against a typical industry range of $20–$25 per day per $100,000 of contract value to flag whether the figure looks reasonable, low, or potentially unenforceable.

Formula

Daily LD rate = Σ(daily category costs); Total exposure = Daily LD rate × Delay days

How it works

  1. Enter the contract value and the delay duration in calendar days, then add daily cost rows by category (lost rental income, extended supervision, financing, administrative overhead, loss of use).
  2. The calculator sums the daily amounts into a calculated daily LD rate and multiplies by the delay duration to get total LD exposure, with a per-category breakdown.
  3. It computes an industry benchmark band from the contract value ($20 and $25 per day per $100K) and rates enforceability: reasonable when near the band, potentially low when far below, and potentially unenforceable when the daily rate runs well above the benchmark high.

Worked example

A $2,000,000 contract delayed 20 days, with daily costs of $250 lost rental income, $150 extended supervision, and $50 administrative overhead.

  1. Calculated daily LD rate: 250 + 150 + 50 = $450/day.
  2. Total LD exposure: 450 × 20 = $9,000.
  3. Benchmark band: 2,000,000 ÷ 100,000 = 20 units → $20×20 = $400/day low and $25×20 = $500/day high.
  4. The $450/day rate sits inside the $400–$500 benchmark band, so it is assessed as reasonable.

A defensible daily LD rate of $450 yields $9,000 of total exposure over 20 days, landing within the $400–$500/day industry benchmark and rated as reasonable.

Frequently asked questions

What makes a liquidated damages clause enforceable?
Courts generally uphold an LD clause when actual damages were difficult to estimate at contract signing and the rate is a genuine pre-estimate of harm rather than a penalty. A rate far above demonstrable daily losses risks being struck down, which is why this tool benchmarks your figure against an industry range.
What does the industry benchmark of $20–$25 per $100K mean?
It is a rule-of-thumb band suggesting a reasonable daily LD rate often falls around $20 to $25 per day for every $100,000 of contract value. On a $2M contract that is roughly $400–$500 per day; rates far outside this range may warrant a closer look at the underlying cost assumptions.
When is a rate flagged as potentially unenforceable?
The calculator flags a rate as potentially unenforceable when it exceeds the benchmark high by more than 50%, and strongly so when it exceeds three times the benchmark high. Such rates may be viewed by a court as a punitive penalty rather than a reasonable damages estimate.
Are liquidated damages the same as actual damages?
No. Liquidated damages are an agreed fixed daily amount set in the contract so neither party has to prove actual losses after a delay. They replace the need to litigate actual damages, provided the rate was a reasonable pre-estimate at the time of contracting.
