Contract Value Calculator
Tender notices quote value in different ways: per month, per year, or as a whole life figure including extensions. This calculator converts between them so you are comparing like with like.
- Initial term value
- £144,000
- Extension value
- £96,000
- Whole life value
- £240,000
Annualised value: £48,000 a year. Only the initial term is committed spend.

How it works
- Enter the recurring value and say whether it is monthly or annual.
- Enter the initial term in months, and any extension option in months.
- The initial term value, the extension value and the total whole life value are shown separately.
- An annualised figure is shown so you can compare contracts of different lengths.
Worked UK example
A contract worth 4,000 a month for an initial 36 months with an optional 24 month extension.
- Initial term: 4,000 x 36 = 144,000.
- Extension: 4,000 x 24 = 96,000.
- Whole life value: 240,000.
The notice may advertise 240,000, but only 144,000 is committed. Plan your capacity on the committed figure.
Understanding your result
Buyers often advertise the maximum whole life value because that is what procurement rules require them to disclose. Extensions are options, not promises. Judge affordability and mobilisation cost against the initial term, and treat the extension as upside.
Frequently asked questions
- Why does the notice value look so high?
- Notices usually state the maximum value including all extensions and sometimes an allowance for volume variation.
- Do framework values mean guaranteed work?
- No. A framework value is a ceiling across all suppliers on it, not an allocation to you.
- Should extension value go in my profit model?
- Model the initial term, then run the extension separately as a second scenario.
