About the multi-currency converter
Most converters only show one target currency at a time. Ours lets you enter a single amount and see it in as many currencies as you like — handy for travel budgets, freelance invoicing across borders, or comparing international prices. Rates are pulled live when you press Convert; if you're offline, the tool falls back to a stored sample table so it still demonstrates the layout.
How mortgage payments are calculated
The monthly payment uses the standard amortization formula: M = P · r(1+r)ⁿ ⁄ ((1+r)ⁿ − 1), where P is the principal, r is the monthly rate (annual ÷ 12) and n is the number of payments. Total interest is simply the sum of every payment minus the amount borrowed.
