How this operation works

What it does: Calculates interest that always falls on the starting capital, without interest on interest, and returns the final total.
What it is for: Checking linear interest charges on short instalment plans, invoices and agreements with a fixed rate over the original amount.
When to use it: Use it when the contract states linear interest, or when you want a baseline to compare against the compound version.
What to fill in: Starting capital, interest rate per period as a percentage, and the number of periods in the contract.
Formula: Interest = capital × rate ÷ 100 × periods. Total = capital + interest.
What each result means: Interest is the whole charge over the period; Total is what you pay at the end, capital plus interest.
Worked example: 10,000 at 2% a month for 6 months: 1,200 of interest and a total of 11,200.

Assumptions: the rate is the one charged per contract period; compound interest capitalises each period; instalments follow the PRICE table with a fixed payment. Insurance, arrangement fees and local taxes are not included.
