// 4. Calculation Logic
// Convert APY to rate logic.
// Note: APY is the effective yield. To get the nominal rate for the compound formula:
// Formula for Amount with APY: A = P * (1 + APY_decimal)^(years) roughly,
// BUT since we have specific compounding frequencies (Daily/Monthly), we use the standard compound interest formula.
// We will treat the input APY as the nominal annual rate (r) for simplicity in this user context,
// as banks often interchange the display slightly, but strictly:
// Balance = P * (1 + r/n)^(n*t)
var rateDecimal = apy / 100;
var years = months / 12;
// Formula: A = P(1 + r/n)^(nt)
var totalBalance = principal * Math.pow((1 + (rateDecimal / compoundsPerYear)), (compoundsPerYear * years));
var totalInterest = totalBalance – principal;
// 5. Formatting Results

Maximizing Returns with Goldman Sachs CDs
Certificates of Deposit (CDs) offered by Goldman Sachs via their consumer banking arm, Marcus by Goldman Sachs, are popular investment vehicles for savers looking for low-risk, guaranteed returns. Unlike standard savings accounts, a CD locks in your interest rate for a specific term, protecting you from market volatility and rate drops.
Use the calculator above to project your earnings. By inputting your deposit amount, the specific term length (usually ranging from 6 months to 6 years), and the current Annual Percentage Yield (APY), you can determine exactly how much interest your money will generate.
How Compounding Works on Marcus CDs
One of the distinct advantages of Goldman Sachs (Marcus) CDs is the compounding schedule. Interest on these accounts is typically compounded daily and credited to your account monthly. This frequency allows your money to grow faster compared to accounts that might only compound monthly or annually.
The calculator above defaults to daily compounding (365 times per year) to provide the most accurate estimate for Marcus CD products.
Key Inputs Explained
Initial Deposit: The lump sum of money you intend to invest. Marcus generally requires a minimum deposit (often $500) to open a High-Yield CD.
APY (%): The Annual Percentage Yield is the rate of return you earn over a year, taking compounding into account. Rates vary based on the term length and the current economic environment.
Term Length: The duration you agree to leave your money in the bank. Early withdrawal usually incurs a penalty, so choosing the right term is crucial for financial planning.
High-Yield vs. No-Penalty CDs
Goldman Sachs offers different types of CDs. A High-Yield CD typically offers the highest rates but charges a penalty for early withdrawal. A No-Penalty CD allows you to withdraw your full balance beginning seven days after funding without a fee, though the interest rate might be slightly lower than the standard High-Yield option.
Why Calculate Your CD Returns?
Before locking away your funds, it is essential to compare the total interest earned against other investment opportunities or inflation. A clear calculation helps you decide if a 12-month term at a specific rate meets your savings goals better than a 5-year term with a potentially different rate structure.
