Financing
You can enter a source in the currency of its contract and see it converted in every total of the plan.
Enter each source in the currency its contract names, for example Swiss francs for a Swiss co-producer or US dollars for a US distributor. Do not convert the amount yourself: an amount you convert by hand keeps the rate of that day, and the row no longer shows the amount in the contract.
Double-click the source's **Amount** cell, or select it and press Enter. KOSMA opens the cell for editing, with a currency list next to the amount. Choose the currency named in the contract. The list shows the currencies of the linked budget (see [how a plan links to a budget](/kb/article/how-a-plan-links-to-a-budget)).
If the currency is not in the list, click **Edit** in the list. KOSMA opens **Currencies** in the linked budget, where you add the currency and its exchange rate. For the steps, see [set currencies and the reporting currency](/kb/article/set-currencies-and-the-reporting-currency).
Type the amount the contract names. KOSMA keeps the amount in the source's own currency: a source set to USD holds US dollars. The total column shows the amount converted into the plan's display currency, and its header names that currency, for example **Total (EUR)**. You choose the display currency in the currency list of the toolbar. At first, it is the default currency of the linked budget.
KOSMA multiplies the amount by the exchange rate of the source's currency and divides the result by the exchange rate of the display currency. Each exchange rate states how many units of the budget's default currency one unit of that currency is worth. You set the rates in **Currencies** in the linked budget.
KOSMA adds up the converted amounts in the totals of the group and country rows, in the **Financing Total** row and in the grand totals next to the grid (see [read the grand totals](/kb/article/read-the-financing-grand-totals)). A plan with sources in several currencies therefore shows one total in one currency.
For example, in a budget with EUR as its default currency, CHF has the exchange rate 0.95. With EUR as the display currency, a source of 160,000 CHF shows 152,000.00 in **Total (EUR)**, and a source of 100,000 CHF shows 95,000.00. The country Switzerland, with these two sources, shows 247,000.00 EUR. With CHF as the display currency, a source of 350,000 EUR shows 368,421.05 in **Total (CHF)**.
**When an exchange rate changes.** KOSMA converts the amounts each time it shows the plan. When someone changes a rate in the linked budget, the total of every source in that currency changes, and every total above it changes with it. Agree with your team when to change rates, because a new rate changes the figures of the plan while others work in it.
