Basic Formulas You Should Know
To understand the process, let’s go over some essential formulas:
1. Simple Interest (SI):
SI=P×R×T100SI = \frac{P \times R \times T}{100}SI=100P×R×T
Where:
- P = Principal amount
- R = Rate of interest (% per annum)
- T = Time (in years)
2. Compound Interest (CI):
CI=P×(1+R100)T−PCI = P \times \left(1 + \frac{R}{100}\right)^T – PCI=P×(1+100R)T−P
3. Profit:
Profit=SellingPrice−CostPriceProfit = Selling Price – Cost PriceProfit=SellingPrice−CostPrice
4. Loss:
Loss=CostPrice−SellingPriceLoss = Cost Price – Selling PriceLoss=CostPrice−SellingPrice
Basic Formulas You Should Know

-
Simple Interest (SI):
SI = (P × R × T) / 100
Where:
P = Principal amount
R = Rate of interest (% per annum)
T = Time (in years) -
Compound Interest (CI):
CI = P × (1 + R / 100)T − P -
Profit:
Profit = Selling Price − Cost Price -
Loss:
Loss = Cost Price − Selling Price -
Profit or Loss Percentage:
Profit % = (Profit / Cost Price) × 100
Loss % = (Loss / Cost Price) × 100
