Simple vs compound interest

Simple interest is charged only on the original principal for the whole period, so it grows in a straight line. Compound interest is recalculated on the principal plus all the interest already earned, so it grows faster over time. The longer you keep money invested, the wider the gap between the two becomes.

Why compounding frequency matters

The more often interest is added back, the more often it starts earning interest itself. Yearly compounding gives the smallest return, while monthly compounding gives the largest for the same headline rate. This tool lets you switch between yearly, half-yearly, quarterly and monthly to see exactly how much the frequency changes your total.

Fixed deposits and savings in Nepal

In Nepal, bank fixed deposits (FD) and recurring deposits pay compound interest, and many savings accounts also compound. Rates differ by bank and by tenure, with longer commitments usually earning more. Use this calculator to compare what different rates and frequencies would return on the amount you plan to deposit.

How banks in Nepal compound

Most Nepali banks compound FD interest quarterly, though some products compound half-yearly or monthly. The frequency is written in the deposit scheme details. Pick the matching option in this tool so the projected total reflects how your specific bank actually credits interest.

Compound interest for borrowers

Compound interest is not only for savers - it also works against you on some loans and on credit-card-style balances where unpaid interest is added to the principal. Understanding the effect helps you see why paying off a revolving balance quickly saves far more than the headline rate suggests.

Reading the result of this tool

The two cards show simple interest and compound interest side by side, each with the total value after your chosen years. The note beneath tells you how much more compounding earned compared with simple interest over the period, which is the real benefit of leaving money invested.

Frequently asked questions

What compounding frequency do Nepali banks use?

Most bank fixed deposits in Nepal compound interest quarterly, while some schemes use half-yearly or monthly compounding. Savings accounts usually compound quarterly or half-yearly. Choose the matching frequency in this tool to mirror your bank.

Is a fixed deposit compounded or simple?

Fixed deposits in Nepal are compounded - the interest is added to the principal at the scheme’s frequency and then earns further interest. That is why an FD grows faster than a simple-interest product at the same rate. This tool shows the compound figure for the frequency you select.

Why is compound interest higher than simple interest?

With compound interest, each period’s interest is added to the principal and then earns interest itself, so the base keeps growing. Simple interest is always calculated on the original amount only. Over many years the difference can be substantial, which is why the tool highlights the extra amount compounding earns.

Can I compare different compounding frequencies?

Yes. Change the compounding frequency buttons and watch the compound-interest card update. For the same rate and tenure, moving from yearly to monthly compounding raises the final total because interest is credited and reinvested more often.

Does this tool account for tax on interest income?

No. It shows the gross interest before any deduction. In Nepal, interest income above the tax-free threshold is subject to income tax, so your take-home return will be a little lower than the figure displayed here.
