Coinage Calculator
Add or subtract coins, then get the result converted to its highest denominator.
About the Coinage Calculator
This free D&D 5e coinage calculator adds or subtracts two piles of coins and returns the total rolled up into its highest denomination. Enter any mix of copper, silver, electrum, gold, and platinum in each row, pick Add or Subtract, and the tool does the exchange-rate math so you do not have to convert 5e currency by hand at the table.
It covers all five denominations of the standard 5e coin economy, and the result is broken back out per coin type so you can hand a player their new balance as platinum, gold, electrum, silver, and copper. Use it to split a treasure hoard, settle a shop purchase, or reconcile the party pouch after downtime.
Tips for Using the Coinage Calculator
- Remember the 5e exchange rates the tool applies: 10 copper to a silver, 5 silver to an electrum, 2 electrum to a gold, and 10 gold to a platinum. The calculator keeps them straight so a stack of copper collapses cleanly into gold.
- Use the top row for the current balance and the bottom row for the change, then Subtract to spend or Add to collect; the result is the new total for the party purse.
- Electrum is optional at many tables. If yours ignores it, just leave those fields blank and the math still balances across the other four coins.
- Pin a running total to your Session Notebook so the party treasury carries from one encounter to the next without re-entering coins.

Common Questions
- Is this coinage calculator free?
- Yes. Every tool on Tools and Taverns is free, with no account, signup, or generation limit.
- What are the D&D 5e coin exchange rates?
- One platinum is worth 10 gold, one gold is worth 2 electrum or 10 silver, one electrum is worth 5 silver, and one silver is worth 10 copper. The calculator applies these rates automatically when it totals your coins.
- What does "highest denomination" mean in the result?
- The tool rolls your total up as far as it will go, so 250 copper becomes 2 gold and 5 silver rather than a heap of coppers. Each denomination is still shown separately in case you want the exact coin breakdown.
- Can I subtract coins to record a purchase?
- Yes. Put the current balance in the first row and the cost in the second, then press Subtract. The result is what remains after the party pays, converted back into whole coins.
- Does it handle electrum pieces?
- Yes. Electrum is one of the five denominations the calculator supports. If your table skips electrum, leave those fields empty and the totals stay correct across the remaining coins.
