Fixed Savings Account Calculator

Fixed savings accounts offer a secure way to grow your money with guaranteed interest rates. This calculator helps you estimate your potential returns based on your deposit amount, interest rate, and term length.

How to Use This Calculator

Enter your deposit amount, select your preferred interest rate and term length, then click "Calculate" to see your estimated returns. The calculator shows both the total interest earned and the final balance after the term ends.

Note: Fixed savings accounts typically offer higher interest rates than regular savings accounts but may have withdrawal restrictions. Always check the terms and conditions of your specific account.

Key Features

Calculates both simple and compound interest
Shows monthly interest breakdown
Visual chart of your savings growth
Comparison of different interest rates

Formula Explained

The calculator uses the following formulas to determine your returns:

// Simple Interest Formula: // A = P(1 + rt) // Where: // A = Final Amount // P = Principal (initial deposit) // r = Annual interest rate (in decimal) // t = Time in years // Compound Interest Formula: // A = P(1 + r/n)^(nt) // Where: // n = Number of times interest is compounded per year // (Monthly compounding is used in this calculator)

The calculator defaults to monthly compounding, which is common for fixed savings accounts. You can adjust the compounding frequency if needed.

Worked Example

Let's calculate the returns for a $5,000 deposit at 3% annual interest for 2 years with monthly compounding:

A = 5000(1 + 0.03/12)^(12*2) A = 5000(1.0025)^24 A ≈ 5000 * 1.0617 A ≈ $5,308.50

In this example, you would earn approximately $308.50 in interest over the 2-year period.

Comparison Table

This table compares the returns for different interest rates over 3 years:

Interest Rate	Simple Interest	Compound Interest
2%	$600.00	$612.25
3%	$900.00	$941.46
4%	$1,200.00	$1,296.35
5%	$1,500.00	$1,693.84

Note: All calculations assume a $5,000 initial deposit and 3-year term.

Frequently Asked Questions

What is the difference between simple and compound interest?: Simple interest is calculated only on the original principal amount, while compound interest is calculated on the initial principal and also on the accumulated interest of previous periods.
How often is interest compounded in fixed savings accounts?: Most fixed savings accounts compound interest monthly. This calculator defaults to monthly compounding but allows you to adjust the frequency if needed.
Can I withdraw money from a fixed savings account before the term ends?: Withdrawal restrictions vary by account. Some fixed savings accounts allow early withdrawals with penalties, while others may have no withdrawal option until maturity.
What factors affect the interest rate I can earn?: The interest rate you earn depends on the account type, your bank's policies, and current market conditions. Online banks and credit unions often offer higher rates than traditional banks.
Is my money protected in a fixed savings account?: Yes, fixed savings accounts are typically insured by government agencies like the FDIC in the US or the FSCS in Canada, up to certain limits.
