Liquidated Damages Calculator
Calculate liquidated damages for construction schedule delays. Apply daily LD rates with contractual cap limits.
About this calculator
This calculator multiplies Daily LD Rate by Delay Days to get Total LDs (Uncapped), then compares that figure against a contractual ceiling -- LD Cap Amount, which is LD Cap (a percentage) applied to Contract Value -- and reports the smaller of the two as LDs Assessed (Capped). At the default inputs, the uncapped total ($75,000) sits well below the cap ($500,000), so LDs Assessed (Capped) simply equals Total LDs (Uncapped), and Contract Value and LD Cap have no effect on the assessed figure in that regime -- only Daily LD Rate and Delay Days move it, since both multiply directly into the uncapped total. Once Daily LD Rate and Delay Days grow large enough that the uncapped total exceeds the cap, LDs Assessed (Capped) flattens out at the cap amount and stops responding to further increases in Daily LD Rate or Delay Days at all -- at that point, Contract Value and LD Cap become the only inputs that can move LDs Assessed (Capped), since they set where the ceiling itself sits.
LD Cap Amount and LDs as % of Contract behave predictably no matter which regime is active: LD Cap Amount always rises directly with both Contract Value and LD Cap, and LDs as % of Contract always falls as Contract Value rises (the same uncapped dollar total becomes a smaller share of a bigger contract). Days Until Cap tells you how many more delay days remain before hitting the ceiling at the current Daily LD Rate -- useful for a contractor tracking exposure as a delay unfolds in real time.

How to Use This Calculator
- Enter Daily LD Rate, Delay Days, and Contract Value.
- Set LD Cap.
- Review LDs Assessed (Capped) ($) and Remaining LD Exposure ($).
- Use Total LDs (Uncapped) ($) and LDs as % of Contract to inform your decision.
- Use the chart to visualize the results and explore different scenarios by adjusting inputs.

What each input means
- Daily LD Rate
- Contractual liquidated damages amount per calendar day of delay.
- Delay Days
- Number of calendar days the project is delayed beyond the completion date.
- Contract Value
- Total contract value for calculating LD as a percentage.
- LD Cap
- Maximum LD as a percentage of contract value (typical: 5-15%).
What each result means
- Total LDs (Uncapped)
- Raw liquidated damages before applying the cap.
- LDs Assessed (Capped)
- Actual LDs applied, limited by the contractual cap.
- LDs as % of Contract
- Uncapped LDs as a percentage of total contract value.
- LD Cap Amount
- Maximum LDs that can be assessed.
- Remaining LD Exposure
- Additional LDs that could still be assessed before hitting the cap.
- Days Until Cap
- Additional delay days before hitting the LD cap.

Frequently Asked Questions
Why do contract value and LD cap percentage sometimes have no effect on the assessed LDs?
LDs Assessed (Capped) is the smaller of Total LDs (Uncapped) and LD Cap Amount. While the uncapped total (Daily LD Rate times Delay Days) stays below the cap -- true at this calculator's default inputs -- LDs Assessed (Capped) simply equals the uncapped total, and Contract Value and LD Cap have zero effect on it. They only start mattering once the uncapped total grows large enough to exceed the cap they define.
What happens once the delay is large enough to hit the LD cap?
LDs Assessed (Capped) flattens out at LD Cap Amount and stops increasing no matter how much further Daily LD Rate or Delay Days rise -- Remaining LD Exposure drops to zero and Days Until Cap reads zero as well. At that point, only raising Contract Value or LD Cap (which push the ceiling itself higher) can increase the assessed LDs any further.
How is the remaining exposure before hitting the cap calculated?
Remaining LD Exposure is LD Cap Amount minus the currently assessed (capped) LDs, floored at zero. Days Until Cap divides that remaining dollar exposure by Daily LD Rate and rounds up, giving a contractor tracking an ongoing delay a running estimate of how many more delay days remain before LDs stop accruing under the contractual cap.
Does a lower contract value always mean lower liquidated damages?
Not necessarily -- Contract Value only affects LDs Assessed (Capped) once the uncapped total (Daily LD Rate times Delay Days) exceeds the cap it sets. Below that point, assessed LDs are driven entirely by the daily rate and delay length, independent of contract value; a smaller contract with a high daily rate and a long delay could still be capped at a lower dollar ceiling than a larger contract with a modest delay.
