Formula Used
SI = P × R × T / 100
Where P = Principal, R = Rate (%), T = Time (years)
A = P × (1 + r/n)^(n×t)
Where P = Principal, r = Rate/100, n = Compounding frequency, t = Time (years)
EMI = P × r × (1+r)^n / ((1+r)^n - 1)
Where P = Loan amount, r = Monthly rate, n = Total months
A = P × (1 + r/n)^(n×t)
Fixed Deposit uses compound interest. Typically compounded quarterly by banks.
M = P × [(1+r/n)^(n×t) - 1] / (1 - (1+r/n)^(-1/3))
Recurring Deposit: monthly installments compounded quarterly.
FV = P × [(1+r)^n - 1] / r × (1+r)
SIP (Systematic Investment Plan): Regular monthly investments with compounding returns.
A = P × [((1+r)^n - 1) / r]
PPF: 15-year scheme, compounded annually at 7.1%. Tax-free returns under Section 80C.
Monthly contribution = 12% (Employee) + 3.67% (Employer) of Basic
EPF: Interest compounded monthly. Current rate: 8.25% p.a.
