Simple interest is charged only on the original principal, never on interest that has already accrued. The formula is Interest = Principal × Rate × Time, with the rate as a decimal and the time in years. Because the base never grows, the interest is the same every year and the balance climbs in a straight line rather than a curve.
For example, 5,000 borrowed or invested at 5% a year for 3 years earns 5,000 × 0.05 × 3 = 750 in interest, for a total of 5,750. Double the time to 6 years and the interest simply doubles to 1,500 — there is no compounding to accelerate it.
Simple interest is common on short-term and some car, personal or bridging loans, and on certain bonds and savings products. Use this calculator to check the cost of such a loan, and compare it with the compound interest calculator to see how much difference compounding makes over longer periods.

Chii chinonzi simple interest formula?
Mutengo wemari yechikwereti = Mutengo wechikwereti x Mutengo wechikwereti x nguva, nemari yechikwereti ichi sechikwereti chekutevera. 5,000 pa5% kwemakore matatu inowana 5000 x 0.05 x 3 = 750.
Chii chinonzi interest simple uye chii chinonzi compound interest?
Simple interest inofungidzirwa chete pamari itsva, saka inokura munzira yakasviba. Compound interest inofungidzirwa pamari itsva pamwe nemari yapfuura, saka inokura nekukurumidza.
Ndinogona sei kufungidzira huwandu hwemari yandakabhadharwa?
Add the interest to the principal. For 5,000 at 5% over 3 years the interest is 750, so the total to repay is 5,000 + 750 = 5,750. The calculator shows both the interest and this total.
Ndinogona here kuisa gore rimwe chete?
Ndinoda. The nguva field inogamuchira fractions, saka 18 mwedzi nde1.5 gore uye 6 mwedzi nde0.5. The interest scales directly with time, so half the years means half the interest.
Ndinogona sei kuwana mari yemubhadharo kubva pamari yandakabhadhara?
Kana 5,000 pamakore matatu akawana 750, mutengo unenge 750 ÷ (5,000 × 3) = 0.05, kana kuti 5% pagore.Kuti uwane 750, shandisa formula inotevera: 5,000 × 3 = 0.05, kana kuti 5% pagore.
Ndeipi nguva iyo kubhadharwa kwemubhadharo kunoshandiswa panzvimbo pekubhadharwa kwemubhadharo wakabatanidzwa?
Izvi zvinoitika kana uchitenga mari yenguva pfupi, mari yechitima kana yemunhu, mari yezvikwereti kana kuti bonds, uye mari yezvikwereti kana kuti notes, apo mari inobhadharwa kunze kwete kuiswazve.
