The deposit calculator looks simple but few people use the real formula: annual vs monthly compounding, 10% interest tax, time-limited promotional rates.

Math formula
Example: 47,500 lei deposit at 5.80% gross for 3 years = 56,245 lei. Gross interest 8,745 lei. After 10% tax: net interest 7,870 lei. Tezaur 3-year at 7.40% gross (tax-free): net 10,545 lei. Government bonds clearly outperform deposits for amounts under 470,000 lei.
Maria Popescu, former Ziarul Financiar journalist: "A reader, Cristina, 43, entrepreneur in Timișoara, chose Tezaur over BCR deposit for 95,000 lei over 3 years. Saving 5,320 lei net. Kept 23,750 lei in liquid deposit as emergency reserve."

Frequently asked questions
What's the deposit calculation formula?
For annual compounding: Final = Initial × (1 + annual rate)^years. For monthly compounding: Final = Initial × (1 + monthly rate)^months. Our calculator shows both gross and net (after 10% tax).
What's the tax on deposit interest?
10% on earned interest, withheld automatically by the bank at each interest payment. For a deposit with 6.30% gross rate, net received is 5.67%.
Does FGDB guarantee the whole deposit?
FGDB guarantees up to 100,000 EUR per person per bank (at the exchange rate at the event date). The sum includes capital plus accumulated interest. For sums above 100,000 EUR at one bank, consider distribution across multiple institutions.
What's the difference between promotional and standard rate?
Promotional rate applies temporarily (3, 6 or 12 initial months) for new clients, then reverts to standard rate, usually 1-2 percentage points lower.
Can I close the deposit before maturity?
Yes, under NBR rules and standard clauses. Early closure usually reduces interest to minimum rate (0.1-1%) and applies retroactively.
