Spreadsheet electricity bill estimator with unit slabs
A single formula with MIN and MAX charges different rates for each block of units, as slab billing does. It shows how step-rate pricing works and how to check it.
Spreadsheet rank list with RANK and a VLOOKUP report card
RANK orders students by total and VLOOKUP fetches one student’s full record by roll number to fill a report card. It shows how lookup formulas turn a data table into a report.
Spreadsheet comparing simple and compound interest over 20 years
Two formulas grow the same sum at the same rate, one adding the same interest each year and one adding interest on interest. The chart shows compounding pulling ahead with time.
Spreadsheet sports day scoreboard using SUMIF
Points from many events are added for each house with SUMIF, ranked and drawn as a bar chart. It shows how one list of results can produce a summary.
