Therefore, it is speculated that the equal principal and interest repayment method is calculated as follows
The loan term is 25 years, and the principal is 93,000 yuan, which is repaid to 620 yuan every month (-stands for multiplier).
Monthly repayment amount = [loan principal × monthly interest rate ×( 1+ monthly interest rate) total repayment period ]≤[( 1+ monthly interest rate) total repayment period-1]
A-monthly repayment amount P-loan amount i-monthly loan interest rate n-monthly loan term.
Pm-loan balance m-monthly repayment period An-monthly repayment accumulation
a=p*[i*( 1+i)^n]/[( 1+i)^n- 1]
PM = a [( 1+I) (n-m power)-1]/[( 1+I) (n-m power)]
Monthly interest rate =4.95‰
Annual interest rate =5.94%
Interest paid in the first month = 93,000 * 4.95 ‰ = 460.35.
Repayment of principal in the first month =620-460.35= 159.65.
Interest paid in the second month = (93000-159.65) * 4.95 ‰ = 459.56.
Repayment of principal in the second month =620-459.56= 160.4.
The third month
. . . . . .
And so on, calculate the monthly sum and subtract it.
65438+4 months interest =6382.66
Repayment of principal =2297.34
93000-2297.34-60000=30702.66
300- 14=286
Insert the above formula =204.24 to recalculate the monthly repayment amount.
2 14.24*286=6 1272.64
620*300= 186000
620* 14=8680
18600-8680= 177320-60000= 1 17320
117320-61272.64 = interest savings of 56047.36 (this result is speechless, it should not be that much, but the calculation principle is good).
After 20 10. 12.26, the benchmark 1-5 6.22% 5-30 6.40%.
There is a five-year interest rate, and it will be the same after five years. This common sense is that there is no problem of 1 to 3 years. You asked the wrong question.
Is there a penalty for shortening it to 36 months? If it must be deducted, according to the current liquidated damages of 1-2%, the inflation rate of 5.3 1%, and the current one-year time deposit interest rate of 2.75%, the static loss in advance is more than 7,000 yuan, regardless of inflation and liquidated damages, and the difference is around 2,000 yuan, which is really too lazy to calculate. You can set a formula yourself.
In addition, CCB has a full-time post-loan account manager position and professional loan management software. Do a calculation and you will know the specific value.
