Percentages  \(a \cdot b\% =a \cdot \frac{b}{100}\)  a = any real number b% = any percent 
Remember to simplify if possible. 
Percentages  \(\% = \frac{\vert ba \vert }{b} \cdot 100= \frac{c}{b} \cdot 100\)  % = % increase or decrease a = new value b = original value c = amount of change 

Percentages  \(P = T \cdot R\)  P = Part T = Total R = Rate 
Percentage of Depreciation 
Percentages  \(C = SP \cdot R\)  C = Commission SP = Selling Price R = Rate 
Commission 
Percentages  \(RR = \frac{Ic}{Iv}\)  RR = Rate of Return Ic = Income Iv = Investment 
Rate of Return 
Interest  \(I = P \cdot R \cdot T\)  I = Simple Interest P = Principal R = Rate T = Time 
Simple Interest 
Interest  \(AI = P \cdot R\) \(QI = AI \div 4\) \(MI = AI \div 12\) \(DI = AI \div 365\) 
AI = Annual Interest P = Principal R = Rate QI = Quarterly Interest MI = Monthly Interest DI = Daily Interest 

Interest  \(CI = P \cdot i\)  CI = Compound Interest P = Principal i = interest rate divided by conversion periods per year 

Interest  \(S = P(1 + i)^n\)  S = Sum = Principal+Compound Interest P = Principal i = interest rate divided by conversion periods per year n = number of conversion periods in the term 

Mortgages  \(DP=SP \cdot \%DPR\)  DP = Down Payment SP = Selling Price %DPR = Down Payment Percent Required 
Down Payment 
Mortgages  \(LTV = \frac {LA}{PV}\)  LTV = Loan to Value Ratio LA = Loan Amount PV = Property Value 
LoanToValue 
Mortgages  \(MLA = PV \cdot LTV\)  MLA = Maximum Loan Amount PV = Property Value LTV = Loan to Value Ratio 
LoanToValue 
Mortgages  \(RDP=PPMLA\)  RDP = Required Down Payment PP = Purchase Price MLA = Maximum Loan Amount 
LoanToValue 
Mortgages  \(MIP=LA \cdot PR\)  MIP = Mortgage Insurance Premium LA = Loan Amount PR = Premium Rate 
Mortgage Insurance Premium 
Mortgages  \(LCF=PLA \cdot 1\%\) \(LOF=LA \cdot 1\%\) 
LCF = Loan Commitment Fee PLA = Promised Loan Amount LOF = Loan Origination Fee LA = Loan Amount 
Fees 
Mortgages  \(LD = LA \cdot PC\)  LD = Loan Discount LA = Loan Amount PC = Points Charged 
Loan Discount Points 
Mortgages  \(LPTI= \frac{LP}{MI}\) \(DTI= \frac{TMD}{MI}\) 
LPTI = Loan Payment to Income Ratio LP = Loan Payment MI = Monthly Income DTI = Debt to Income Ratio TMD = Total Monthly Debt 
Income Ratios 
Mortgages  \(MALP = (\frac{LA}{\$1000}) \cdot LF\)  MALP = Monthly Amortized Loan Payment LA = Loan Amount LF = Loan Factor (per $1000 of loan amounts) 
Amortized Loan Payment 
Mortgages  \(TMLP = MALP + \frac{1}{12} PT + \frac{1}{12} HI\)  TMLP = Total Monthly Loan Payment PT = Property Taxes HI = Homeowners Insurance 
PITI Payments
