About the loan calculator
This calculator covers three common borrowing structures. Pick the tab that matches your loan.
An amortized loan is repaid with equal monthly installments; each one pays the interest due and reduces the principal. A deferred payment loan has no payments until the end: interest compounds, and you repay principal plus all accrued interest in a single lump sum. A bond tab shows how much a bond with a given face value pays out today if it is sold at a discount and redeems at face value at maturity.
Reading the results
For amortized loans you also get a pie chart of principal versus interest, a balance-over-time chart and a yearly or monthly amortization table. The yearly rows add up exactly to the monthly rows, and the final balance is exactly 0.00.
Formula
Amortized: M = P × r ÷ (1 − (1 + r)^−n), r = annual rate ÷ 12, n = months
Deferred: Amount due = P × (1 + rate ÷ k)^(k × years), k = compounding periods per year
Bond: Proceeds = Face value ÷ (1 + rate ÷ k)^(k × years)
Example
Borrowing $100,000 at 6% for 10 years with monthly payments costs $1,110.21 a month ($133,224.60 in total, $33,224.60 of it interest). If the same $100,000 were a deferred loan compounded monthly, you would owe about $181,939.67 after the 10 years.
