What this calculator does
Tracking money in five coin types is where a table slows down: the rogue has 3 electrum, 25 copper and a few silver, the shopkeeper wants 9 gp 5 sp, and somebody has to do the division. This tool does the arithmetic from the exchange table in the SRD, where a gold piece is worth ten silver or a hundred copper, a platinum piece ten gold, and an electrum piece five silver.
It works in copper internally so there is never a rounding error, then reports the same purse as an amount of each coin type, as the fewest coins that make the total, and as change if you enter a price. Consolidating a bag of loose coins into fewer, larger ones is also a good way to see how much weight a character could drop.
Worked example
A purse holds 2 pp, 14 gp, 3 ep, 7 sp and 25 cp. In copper that is 2,000 + 1,400 + 150 + 70 + 25 = 3,645 cp, or 36 gp 4 sp 5 cp. Carrying 51 coins now, the fewest that make the same value is 18: 3 pp, 6 gp, 4 sp, 5 cp. Paying a price of 9.5 gp (950 cp) leaves 2,695 cp, which is 2 pp, 6 gp, 1 ep, 4 sp, 5 cp in the fewest coins.
How it is calculated
Every coin is converted to copper using the SRD Standard Exchange Rates table: 1 cp = 1, 1 sp = 10, 1 ep = 50, 1 gp = 100, 1 pp = 1,000 copper. The total is the sum. Showing the total in another coin type is a division by that coin's copper value. The fewest-coins breakdown takes as many of the largest coin as fit (platinum, gold, electrum, silver, copper in that order). For these coin values that greedy method gives the true minimum, which the test suite confirms by brute-force search. Ticking "no electrum" removes electrum from the change.

What this does not cover
- Merchants who will not make change, or coins that are hard to spend in a setting, are a table decision and not modelled.
- Exchange rates are the 5e ones. Other games or settings may price electrum or platinum differently.
- Fractions of a copper piece are not possible. Prices are rounded to the nearest copper.
- Gems, trade goods and barter are valued by the table, not by this converter.
Common mix-ups
-
Often assumedAn electrum piece is worth one gold piece, or ten silver.
What the source saysThe SRD exchange table makes one electrum piece worth five silver pieces, which is half a gold piece. [1]
-
Often assumedPlatinum is worth a hundred gold pieces.
What the source saysThe SRD makes one platinum piece worth ten gold pieces, one hundred silver or a thousand copper. [1]

Frequently asked questions
How much is an electrum piece worth in D&D?
Five silver pieces, which is half a gold piece. The SRD exchange table lists 1 ep = 5 sp = 1/2 gp.
How many copper pieces are in a gold piece?
One hundred. A gold piece is ten silver and a silver piece is ten copper, according to the SRD.
What is a platinum piece worth?
Ten gold pieces, or 1,000 copper. It is the largest coin in the SRD table.
How do I make change for 9 gp 5 sp?
Enter the price as 9.5. The tool subtracts it in copper and returns the remainder as the fewest coins, so the party sees how many of each coin it keeps.
Why does the fewest-coins list sometimes use electrum?
Because an electrum piece is worth 50 copper, using it can cut the coin count. Tick "no electrum" if your table avoids it and the tool will make change in gold, silver and copper only.
