Average of Percentages Calculator
Averaging percentages looks trivial until the groups behind them are different sizes.

Fraction Addition Calculator

-
Peak Value Calculator
Give this calculator a starting amount, a growth rate and a time horizon, and it projects the peak value of the investment: the largest it can reach under steady compound growth.

Royalty Payment Calculator
Royalty checks look simple until the statement arrives: a percentage of revenue, an advance that was paid months ago, and a list of deductions you did not agree to.

Split Payment Calculator
Four friends, one check, and the usual thirty seconds of everyone staring at it.
Some questions come up once and do not fit a specialist category. A tip at a wedding, the right TV size for a room, the words on a cheque written out in full, or the value of a guitar chord change — the tools here cover that scattered ground. The Check Writing Calculator, the TV Size Calculator and the Guitar Chord Calculator sit alongside dozens of smaller helpers, each built around one ordinary job.
Much of the collection turns on comparing like with like. Cost tools put a price on groceries, plaster, bottled water or a sprayer job; rate tools work out click-through, billing, baud or yearly rates; length and volume tools handle rooms, wells, pipes and bolts. Discount and percentage tools do the same for prices and growth, so a sale price, a wedding tip or a year-over-year change can be checked in seconds rather than estimated.
The point throughout is practical: the inputs are the numbers a person would already know, and the output is a figure that can be used straight away, for a purchase, a job or a household decision.
