Compound interest is interest earned on both your original money and the interest it has already earned. Because each interest payment starts earning interest of its own, a balance grows along a curve rather than a straight line. This calculator projects the future value of a starting balance plus optional regular contributions, using the formula A = P(1 + r/n)^(nt) for the lump sum and the future-value-of-a-series formula for the ongoing deposits, compounded as often as you choose.
For example, 1,000 invested for 10 years at 7% a year, with 100 added every month, grows to about 19,300. Of that, roughly 13,000 is money you actually paid in (the 1,000 start plus 120 monthly deposits) and about 6,300 is interest the account earned for you — money that came from nothing but time and compounding.
Use the solve-for tabs to run the projection backwards: instead of the end balance, pin a target and solve for the starting amount, the return rate, the monthly contribution or the number of years you need. That makes it a planning tool for a house deposit, a college fund or any long-term savings goal.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani chofunika kwambiri?
Nthawi zambiri ndalama zosapanga dzimbiri, zambiri mupeza, chifukwa chilichonse chindapusa chatsopano chimayamba kulandira ndalama zosapanga dzimbiri mofulumira. Mphamvu ndi yaying'ono koma yoyenera panthawi yaitali.
Kodi ndi chiyani formula chuma chosapanga dzimbiri?
A = P (1 + r / n) ^ (nt) kwa ndalama imodzi, kuphatikizapo mtengo wa mtsogolo wa mnda kwa ndalama zoyendera.
Kodi solve-for tabs kuchita?
M’malo mwake kokha kuwerengetsa mapeto malire, kusankha tabu kuchira kwa osiyana odziwa - ndalama zoyamba, mitengo yobwezera, mwezi msonkho kapena ochepa zaka zofunika kuti afike zofuna tsogolo malire. Umboni kuchira ndi kutchulidwa ndi zofuna mapeto malire amagwiritsa ntchito.
Kodi pali kusiyana kotani pakati pa ndalama zosawerengeka ndi ndalama zosawerengeka?
Mtengo wa ndalama za m’dziko la United States ndi wotsika kwambiri kuposa m’mayiko ena, ndipo ndalama za m’dziko la United Kingdom ndi zotsika kwambiri kuposa ndalama za m’mayiko ena. Mtengo wa ndalama za m’dziko la United States ndi wotsika kwambiri kuposa m’mayiko ena, ndipo ndalama za m’dziko la United Kingdom ndi zotsika kwambiri kuposa ndalama za m’mayiko ena.
Kodi kupatsa ndalama pamapeto pa mwezi kumathandiza?
M'malo mwake, ndalama zoperekedwa pamapeto pake zimabweretsa ndalama zowonjezera zokhudzana ndi ndalama zoperekedwa pamapeto pake. M'zaka zambiri, nthawi yosankha imawonjezera mpaka ku kusiyana kocheperako koma koyenera - sinthani pansi pa zosankha zazikulu.
Kodi ndi chiyani lamulo la 72?
Ndi njira yocheperako kwa nthawi yayitali ndalama zimatenga kuti zidutse: divisi 72 ndi chaka chatha peresenti mtengo. Pa 7% chaka, 72 ÷ 7 ≈ 10 zaka kuti zidutse. Ndi zosawerengeka, koma chitsimikizo chida chikhulupiriro kudzera mwa mfundo yoyenera chiwonetsero ichi calculator amapereka.
Kodi pali kusintha kwakukulu bwanji pa mtengo wobwerera?
A lalikulu. Chifukwa cha kukula compounds, awiri extra peresenti zigawo zobwezera angathe pafupifupi double the final balance over 20 or 30 years. Try changing only the rate to see how sensitive long-term investing is to it.
