EboraBot Engineering Economics Figure Solver
Snap or upload a cash-flow diagram (the time line with up arrows for receipts and down arrows for costs) — or a cash-flow table or cost/revenue chart — and EboraBot reads it for you: it lists every cash flow, the interest rate, the periods, and what you're being asked to find, then solves the time-value-of-money problem step by step with the right factors and tells you the answer. Great for P/F, P/A, F/A, gradients, equivalence, annual worth, and break-even from a diagram.
📷 Upload or photograph a cash-flow diagram — a time line with up/down arrows, a cash-flow table, or a cost/revenue (break-even) chart. EboraBot reads every cash flow, the rate i and the periods n, identifies what's being asked, then solves the equivalence step by step using the correct interest factors. Costs 15 EP per diagram.

Before you analyze
EboraBot reads your diagram with AI vision, then solves it. Heads up:
- It can misread a number — a cash-flow amount, the interest rate, or the number of periods. A blurry or handwritten figure is riskier.
- If the rate isn't printed on the figure, type it in the question box or add it as a free correction afterwards.
- Always check the "What EboraBot read" box before trusting the answer — the free correction box fixes any misread value.
- The solution is a study aid. Confirm against your notes, factor tables, and what your professor taught.
How the Eng Econ Figure Solver works
Upload or photograph a cash-flow diagram, cash-flow table, or cost/revenue chart and EboraBot reads every cash flow, the rate and periods, and solves the equivalence step by step. Heads up:
- Costs 15 EP per diagram (the AI-vision step is the heavy part).
- Best for figures — cash-flow diagrams, tables, and break-even charts. For pure word problems use the Eng Econ Worded Solver (cheaper).
- Make sure the interest rate is visible in the photo, or type it in the question box — many diagrams give i in the surrounding text.
- Take a sharp, well-lit photo and crop to just the diagram so the arrow amounts and the time axis are readable.
