+<p>Remember that we credit member balances for Checkout payments <b>after subtracting <a href="https://checkout.google.com/seller/fees.html">Checkout's service fees</a></b>. This means that, to increase your balance by a particular amount, you must make a <b>larger</b> payment than just that amount. The current fees are 2% plus 20 cents. This means that you can calculate the amount <i>x</i> to send from the amount <i>y</i> you want us to receive with this formula: <i>x</i> = (<i>y</i> + .2) / (1 - .02).</p>
