Calculator vs Accrue

Compound interest is a method used to calculate interest on an investment. It involves adding together the principal amount and the previously generated interest to determine the next interest payment. Unlike simple investments that earn a fixed amount of interest each time, compounding investments accumulate more and more interest, resulting in exponential growth of your assets over time.

Accrue is a compound interest calculator for a strategy quoted per trading day. Enter the gain you are aiming for each market day — 0.300% — and Accrue compounds it over the 252 days a year the market is open, then says what that comes to in the terms everyone else uses: APR, APY, and the same rate read on a calendar basis. It is one screen. Every input is a field you edit with the chart in view, and the answer moves as you type. FEATURES • The daily rate is the input, not an annual figure divided down • 252 market days or 365 calendar days, switchable — and it shows what your rate is on the other one • Contributions daily, weekly or monthly • Term in days, months or years • The chart's time scale is an input too: read the same projection in days, weeks, months, quarters or years • Drag along the curve to read any point out • A breakdown table that unfolds underneath, at whatever scale you chose • Opens on whatever you left in it • Light and dark, or follow your iPhone WHY THE DAY COUNT MATTERS A gain earned per trading day compounds about 252 times a year, not 365. At 0.300% a day that is 112.73% APY on a market basis against 198.43% on a calendar one — the same number, read two ways, and the difference only means something because the daily rate is what you typed. NOT A FORECAST Accrue projects one scenario: the rate you enter, held every single day. No strategy does that, and the app makes no claim that any rate is achievable. It is a tool for seeing what compounding does. No account, no network, no tracking. Every feature is free; the optional tips in Settings unlock nothing.
