Calculate simple interest (I = P × r × t), total accrued amount, annual interest payouts, and loan durations with step-by-step mathematical formulas.
Computes Interest (I = P × r × t) and Total Future Amount (A = P + I) with full step-by-step arithmetic.
Calculate loan tenure in Years, Months, or exact Days with 360-day (ordinary) and 365-day (exact) modes.
Solve for Principal (P), Rate (r), Time (t), or Total Interest (I) dynamically.
Calculate financial loan agreements locally with complete data security.
The Simple Interest Calculator uses the linear equation I = P × (r / 100) × t, where P is principal, r is annual percentage rate, and t is time in years.
For tenure given in months, t = months / 12; for days, t = days / 365.
The total maturity value is calculated as A = P + I with penny-perfect precision in client JavaScript.
Calculate total interest on a $5,000 short-term personal loan for 9 months at 6% simple interest ($225).

Calculate non-compounding interest earned on 1-year and 3-year term deposits.
Simple interest is calculated only on the original principal amount, whereas compound interest is calculated on the principal plus previously accumulated interest.
The formula is I = P * r * t, where I is Total Interest, P is Principal, r is annual interest rate as a decimal, and t is time period in years.
Yes. Softnag allows you to specify loan duration in years, months, or exact days.
No. All calculations run strictly inside your local browser memory.
Yes. Softnag can solve for any unknown variable: Principal, Interest Rate, Time, or Total Interest.
Simple interest is calculated solely on the original principal amount, whereas compound interest accumulates on both the principal and previous interest periods.
