How to Calculate CIT (Compound Interest) — Step by Step

A = P × (1 + r/n)^n×t

1. P = principal (your initial deposit)
2. r = annual interest rate as a decimal (4.5% → 0.045)
3. n = compounding periods per year (365 daily, 12 monthly, 2 for CDs)
4. t = time in years
5. A = final amount. Subtract P to get the interest earned.

Example: $10,000 at 4.5% compounded daily for 5 years → A = 10,000 × (1 + 0.045/365)^365×5 ≈ $12,521.47 — interest earned: $2,521.47. Add monthly deposits and the calculator simulates each month sequentially for exact results.

Pro Tips for Accurate Projections

• APY vs rate: if your bank quotes APY, you can enter it directly with compounding set to "Annually" — APY already includes compounding effects.
• CDs lock the rate: a CIT CD's APY is fixed for the whole term — projections here are exact, unlike variable savings rates.
• Taxes are not included: interest is taxable income in most jurisdictions; subtract your marginal rate from earnings for after-tax reality.
• The monthly-deposit nuance: this calculator adds deposits at month-end and compounds daily on the running balance — conservative vs banks that pay from day-of-deposit.
• Withdrawal drag: this tool assumes no withdrawals; regular pulls change the math significantly.

Frequently Asked Questions

A CIT calculator is a compound interest tool for projecting savings and CD growth — CIT here stands for the compounding math itself (some people also search it for CIT Bank). Enter a deposit, rate, years and compounding frequency to see your final balance, total interest, and a year-by-year table.

Use the formula A = P × (1 + r/n)^(n×t): multiply the principal by one plus the rate divided by compounding periods, raised to the power of periods times years. $10,000 at 4.5% daily for 5 years → $12,521.47. The calculator above runs this instantly with a full breakdown.

Yes — enter the product's APY (Platinum Savings around 4.70%, Savings Connect around 4.55%), set compounding to Annually (APY is already compounded), and project any deposit and timeline. Rates shown here are for reference; confirm current ones on CIT Bank's official site.

Choose the Semi-annually compounding option (how most CIT Bank CDs accrue), enter the CD's APY for its term, and your deposit. The yearly table shows exactly what the CD pays at maturity — helpful for comparing 6-month vs 5-year ladders.

CDs lock your money for a fixed term at a fixed rate (higher APY, penalty for early withdrawal); high-yield savings stays liquid with a variable rate. Run both in this calculator — a 5-year CD at 5.05% vs savings at 4.70% with monthly deposits shows the trade-off in real dollars.

No — it shows gross interest, which is what banks quote. Interest is typically taxable income the year it's earned; subtract your marginal tax rate for after-tax results. There are no fees in the math because reputable savings products don't charge any.

More frequent compounding pays interest on interest sooner. Daily compounding on 4.5% yields about 4.598% effective annually vs 4.594% monthly — small differences that compound into real money over decades. The dropdown lets you test each case exactly.
