Compare investment returns and cash timing, estimate runway and examine how working capital ties up funds.
Which calculator should I use?
Use ROI for a simple return ratio, payback for recovery time, and NPV or IRR when cash flows occur across periods. Runway estimates how long cash lasts under the stated burn rate. The cash conversion cycle explains inventory and payment timing rather than investment profitability.
