So, let’s embark on this enlightening voyage as we navigate the intricacies of calculating compound interest, which promises to illuminate the path toward sound financial decision-making and wealth accumulation.

What is Compound Interest?

Compound interest refers to the interest earned on the initial principal and the accumulated interest from previous periods. Unlike simple interest, which is calculated solely on the principal amount, compound interest accounts for the growth as interest accumulates over time. This compounding effect results in exponential growth, showcasing the beauty of time and consistency in wealth accumulation.

The Significance of Compound Interest

  • Exponential Growth: Compound interest embodies the concept of exponential growth. Over time, even small amounts can grow significantly due to the snowball effect of continually compounding interest.


  • Long-Term Savings: Compound interest is the driving force behind long-term savings and investments. It encourages individuals to start saving early, as the longer the money is invested, the more significant the compounding effect becomes.


  • Wealth Accumulation: Individuals can amass substantial wealth over time by allowing interest to compound. This wealth can support retirement, education, major purchases, and more.
  • Investment Returns: Investors benefit greatly from compound interest, as it enhances the returns on investments such as stocks, bonds, and mutual funds over extended periods.Applications of Compound Interest
  • Savings Accounts: Many savings accounts offer compound interest, enabling account holders to see their money grow over time.


  • Investments: Compound interest plays a vital role in various investments, including retirement accounts (like 401(k)s and IRAs), certificates of deposit (CDs), and mutual funds.


  • Loans and Debt: Compound interest also applies to loans and debt. Borrowers pay interest on the principal amount; over time, interest accrues on both the principal and the outstanding interest.Advantages of Compound Interest
  • Maximized Returns: Compound interest generates larger returns over time than simple interest, making it a powerful tool for wealth accumulation.


  • Passive Growth: Once set in motion, compound interest grows your money passively, requiring minimal effort.


  • Encourages Early Saving: Compound interest motivates individuals to start saving early, harnessing the full potential of time in growing their money.

Disadvantages of Compound Interest

  • Accrued Debt: Contrarily, compound interest can lead to substantial debt if not managed properly. High-interest credit cards and loans can lead to spiraling debt due to the compounding effect.


  • Limited Control: Compound interest requires time to show substantial growth. It might be better for individuals seeking quick returns or needing immediate access to their funds.

The Underlying Meaning of Compound Interest

Compound interest encapsulates the adage “money makes money.” It highlights that your initial investment works for you, and the returns generated further contribute to your wealth. This concept underscores the importance of consistency, patience, and the impact of time on financial growth.

Calculating Compound Interest

Calculating compound interest can seem like a daunting task. Here is, however, a simple way to do it on a simple calculator. 


So take the original capital, say $1000, as 1, then the interest, say 3%, as 0.03. That gives 1.03. Now, multiply that by 1000, and then do that 24 times. That is because of the rule of 72s, which starts by dividing 72 by the interest value. That gives a total of $2032.


Compound interest is a pivotal concept in finance with far-reaching implications. Its exponential growth potential, long-term savings benefits, and role in wealth accumulation underscore its significance. While it offers advantages like maximized returns and passive growth, it also demands careful management to avoid the pitfalls of accrued debt. Ultimately, compound interest embodies the essence of financial wisdom: planting the seeds of savings and investments today to reap the rewards of compounded growth in the future.

So you have decided to buy silver online.

Great choice. Let’s talk about silver.

Silver is exceptionally popular today. Part of the reason for this is the belief that it’s potential for upside value increase is even greater than the same belief in gold. In fact, there is a very good book on this subject entitled: “ Why Silver Will Outperform Gold by 400% in the coming years”. It’s a very scholarly book and quite convincing. Give it a read if you have the time.

Mind you, one need not look as far as that book to find evidence of the common belief that silver has great potential for growth in the near future. All one has to do is go to the web or even Youtube and there are advocates of this thought at every turn.

At Durham Precious Metals we believe that silver is an easy choice because it gives a sense of substance due to its lower cost per ounce than gold.

Silver Bullion

Probably 90% of our business is silver sales so this sentiment is fairly unanimous throughout the public. 10oz bars seem to be the most popular. Generic rounds and Silver Maples seem to be the next most popular and 1oz bars a close 4th place. It is our opinion that 10 oz bars and 1oz rounds are your best value as their premium over spot is very reasonable. However, there is no wrong choice when it comes to our silver product line because we try to concentrate on product lines with low premiums anyway.

Silver has always been a form of money. There are those that will argue that silver has been demonetized but we beg to differ. All one has to do is refer to the (CCRA) definition for 999 bullion. It is deemed by Rev Can to be a “ financial instrument”. Enough said on that subject!

Best Place to Buy Silver

From a utility standpoint, silver has somewhere in the neighbourhood of 60,000 industrial uses including painting the backs of mirrors to create the reflective surface to collecting radiation in solar panels. If nothing else, the lack of an above ground supply of silver ( which is relatively new historically) will keep the demand for this metal strong since for most applications there is no viable substitute.

Can you imagine the mayhem that would ensue if all the major electronic manufacturers came grinding to a halt due to a silver shortage? It would be catastrophic to the economy. We believe that this fact alone will be a major driver of support for the silver price when the powers that be run out of tricks in their attempt to suppress the price of silver. And yes, we agree that this practice goes on in plain sight and that the regulators turn a blind eye. Let’s hope justice prevails and that the historic silver/gold ratio returns to its traditional level.

So you have decided to buy gold online.

Great choice! Let’s talk about gold then, shall we?

Gold is, and always has been, a favorite of collectors of precious metals. Its 6000-year history of sustaining wealth is unprecedented. The yellow metal has launched wars, bought fortunes and has been a form of money throughout that history. It is one of the densest metals and also one of the densest elements on the periodic table. It weighs in at a density of 19.32 grams per cubic centimeter. Water, by contrast, has a density of 1 gram per cubic centimeter.

Platinum is the densest of the common 4 precious metals at 21.45 grams per cubic centimeter.

People will often ask when gold is the right choice to buy as opposed to other metals such as silver. This is a very common question. There is no easy answer that anyone can give to someone so we always boil it down to practical applications.

Consider how much of an investment you are planning to make over-all throughout the course of your precious metals buying.  If you are planning on purchasing, for example, $10,000 worth of metals and then cap your spending then it really doesn’t matter which metals you buy. The volume of the purchase will be relatively small in terms of weight and size. Our main concern and Durham Precious Metals comes down to simple things like , cost of storage, cost of shipping and bulk. We are always trying to help our customers have the best experience as metals collectors.

Buy Gold Near Me

For example, if you were to tell us that you are considering selling a piece of real estate and use the proceeds to buy metals then gold would be our suggestion. The reason comes down to volume and weight at this point. Several hundred thousand dollars of silver would be an incredible amount of bulk at this spend level. Hundreds of pounds of silver would be hard to store practically and would be more expensive to store as well. If you are the DIY type it would also be harder to hide than a comparable dollar amount of gold.

Keep in mind that at the time of this writing gold is about 75 times more expensive in dollar terms as the same weight of silver. That equates to 75 times less bulk per dollar spend. This will make it much easier to hide or store if you are looking at large purchase amounts.

Price of Gold?

If you are only considering a small total purchase amount either of the metals is perfectly fine. The one consideration we always emphasize for small purchase amounts really comes down to personal perception. Here is what we mean. Silver is 75 times more bulky per dollar spend. Obviously, it is going to feel a lot more substantial if you buy $5000 worth of silver and have several hundred ounces to admire than only about 3 ounces. It’s a perception thing at this point but perception matters to people since perception can make us feel a particular way about what we spend our money on.

In closing, gold and silver are both great choices and neither is wrong in terms of their value of utility. They have both had a long history as a store of wealth and that isn’t likely to change any time soon.
