Tools

Small calculators and checkers that run entirely in your browser. Nothing is sent anywhere, and none of them need an account.

Crypto

Which network is this crypto address on?
Paste a wallet address and find out which chain it belongs to — before you send.

Stocks

What is a fund's annual fee really costing you?
A 1.5% charge does not cost 1.5%. See what it costs over your holding period.

Currencies

What did that transfer really cost?
The advertised fee is the smaller half. This shows the rest.

Gold & Silver

How much of this jewellery price is actually gold?
Split a quoted price into metal value and making charges.

These tools are for education. They work from the numbers you type and cannot see your accounts, verify who owns an address, or account for your circumstances. Nothing here is financial advice.
