Contingency hours
Turns risk into visible time for revisions, coordination and small changes.
Finance
Turn hours, expenses and risk into a clear quote, or check whether a fixed price truly works.
From estimate to quote
Compare how price changes when more or less project time is reserved.
Milestone payments
The amounts add up to the total presented to the client, including any added tax.

A good price does more than cover hours: it makes risk visible and leaves room to operate.
Turns risk into visible time for revisions, coordination and small changes.
Margin shows what share of price remains after work, expenses and fees.
Reviewing funded hours and effective rate helps detect quotes that are too tight.
Define deliverables, included revisions, and what constitutes a scope change. Contingency reduces risk but does not replace clear agreements.
Separate added tax from available revenue. Also confirm when direct expenses are paid and what happens if the project is paused.
Estimate hours for each phase, assign a sustainable rate, add direct expenses and reserve time for contingencies. Then include fees and a business margin before tax.
It depends on how well defined the scope is. Contingency reserves hours for coordination, revisions and small changes; compare it with base and conservative scenarios.
Margin measures what percentage of price remains after costs and fees. Markup simply adds a percentage to cost and does not guarantee the same margin.
Review its effective rate, achieved margin and how many hours it can fund before falling below the modeled value of your time.
A deposit helps fund the start and reduces collection risk. The right percentage depends on the project, client and upfront expenses.
Not in this calculator. Added tax is shown separately and is not treated as available revenue for work, expenses or margin.
Include only expenses required for the project, such as licenses, materials, travel, contractors or hired services.
