Add an entry once and Interest Edge keeps calculating the interest right up to today. WHY INTEREST EDGE β’ Lent and borrowed in one place β see who owes you and whom you owe at a glance. β’ Interest done for you β Simple, Compound, or NIL, with your choice of day-count basis (actual/365 or 30/360). β’ Your own interest rates β save the presets you actually use and reuse them in a tap. β’ Capital return dates β record when money is due back, by period or by date. β’ Person-wise ledgers β every transaction with a person, netted to a single receivable or payable. β’ Powerful search β find any entry by name, amount, rate, date, or note. β’ Reports β financial-year summaries of principal and interest. β’ Settle and reopen β mark entries settled, with a full history of every change. β’ Private by design β your ledger is tied to your account and visible only to you. No ads, no tracking. MADE FOR EVERYDAY MONEY Interest Edge speaks in rupees and the way lending really works β principal, rate per annum, simple vs compound, and clear receivable and payable totals. Sign in with a username or with Google, and your ledger is saved securely to your account. Interest Edge is a personal record-keeping and calculation tool. It is not a bank, lender, or financial advisor, and does not move money.
