FAQ
What is the difference between simple and compound interest?
Simple interest applies the rate to the original principal only. Compound interest reinvests each period's interest so the balance accelerates over time. Reviewing both side by side helps you gauge the opportunity cost of not compounding.
Why can't the IRR be calculated?
IRR requires at least one negative and one positive cash flow. Some patterns produce multiple IRRs or none at all, so the solver may fail to converge. Adjust the cash flows or rely on the NPV table to compare scenarios.
