Construction Escalation Calculator
Project a construction cost forward at an annual escalation rate — with a simple or compound model — to see the projected cost, the dollar increase, and the percent increase over your time period.
Escalating $1,000,000 at 6% per year (compounded annually) over 24 months projects to about $1,123,600 — an estimated increase of $123,600. This is a generalized estimate from your own assumptions, not a contractor quote or a guaranteed future cost.
Assumptions
- The escalation rate you enter is treated as an annual rate.
- Compound applies the rate on each prior year’s escalated amount (annual compounding); Simple applies a flat rate × years.
- Months are converted to years (months ÷ 12), so fractional periods are supported.
- Negative or non-numeric inputs are rejected with a visible message, never silently adjusted.
Worked example
A $1,000,000 base cost escalating at 6% per year, compounded, over 2 years projects to $1,123,600 — a $123,600 (12.36%) increase. On a simple model it would be $1,120,000.
Escalation is the cost of time. So is a stalled site.
Every month a financed project sits idle, cost escalation keeps compounding on work that isn't getting done. Ground Stasis watches your site by satellite and flags when it goes unusually quiet — so you learn about a stall in weeks, not at the next draw.

Common questions
What is construction cost escalation?
Construction cost escalation is the increase in the cost to build over time, driven by changes in materials, labor, and market conditions. An escalation rate expresses that increase as an annual percentage, which you can project forward over a construction or delay period.
Does this use simple or compound escalation?
Both — you choose. Compound applies the annual rate on top of each prior year's escalated amount (annual compounding), the more common convention for multi-year projections. Simple applies a flat rate times the number of years. The result states which model it used.
What escalation rate should I use?
That depends on your market, project type, and time frame, and it changes over time. This tool does not prescribe a rate — enter the figure your own cost data or cost consultant supports. The result is only as reliable as that assumption.
Is this a construction quote or a guaranteed future cost?
No. It is a generalized estimate based entirely on the assumptions you enter. It is not a contractor quote, a bid, or a guarantee of what a project will actually cost. Use it to understand scale and sensitivity, not as a project-specific price.
