House Loan Repayment Formula Explained

The calculator uses the standard mortgage amortization formula.

Monthly Payment Formula

M=P×r(1+r)n(1+r)n1M = P \times \frac{r(1+r)^n}{(1+r)^n -1}M=P×(1+r)n−1r(1+r)n​

Where:

SymbolMeaning
MMonthly payment
PLoan amount
rMonthly interest rate
nTotal number of payments

Monthly Interest Rate

r=Annual Interest Rate12×100r = \frac{\text{Annual Interest Rate}}{12 \times 100}r=12×100Annual Interest Rate​

Number of Payments

n=Loan Term in Years×12n = \text{Loan Term in Years} \times 12n=Loan Term in Years×12

This formula ensures that each monthly payment covers both principal and interest while fully repaying the loan by the end of the term.

This example shows how interest significantly increases the overall cost of borrowing over long periods.


Understanding Your Calculator Results

The calculator provides four key outputs.

Monthly Repayment

This is the amount you'll pay every month.

It includes:

  • Principal repayment
  • Interest charges

This figure helps determine whether the mortgage is affordable within your monthly budget.


Total Repayment

This represents the complete amount paid to the lender throughout the loan term.

Formula:Total Repayment=Monthly Payment×Number of Payments\text{Total Repayment} = \text{Monthly Payment} \times \text{Number of Payments}Total Repayment=Monthly Payment×Number of Payments


Total Interest

This is the total cost of borrowing.

Formula:Total Interest=Total RepaymentLoan Amount\text{Total Interest} = \text{Total Repayment} - \text{Loan Amount}Total Interest=Total Repayment−Loan Amount

A lower interest rate can save thousands of dollars over the life of a mortgage.


Number of Payments

This shows how many monthly installments will be required.

Examples:

Loan TermPayments
10 Years120
15 Years180
20 Years240
25 Years300
30 Years360

How Interest Rates Affect Mortgage Payments

Interest rates have a major impact on repayment costs.

Consider a $300,000 loan over 30 years:

Interest RateMonthly Payment
4%$1,432
5%$1,610
6%$1,799
7%$1,996
8%$2,201

Even a small increase in interest rates can significantly increase monthly expenses and total interest costs.


How Loan Term Impacts Repayments

Longer loan terms generally reduce monthly payments but increase total interest paid.

Example: $250,000 Loan at 5%

Loan TermMonthly PaymentTotal Interest
15 Years$1,976$105,680
20 Years$1,650$146,035
30 Years$1,342$233,139

Shorter loan terms usually save money in the long run.

Many homeowners choose to make extra payments whenever possible.

Benefits include:

  • Lower total interest costs
  • Faster home ownership
  • Increased home equity
  • Reduced financial stress
  • Greater long-term savings

Even small additional monthly payments can significantly shorten the loan term.
