This calculator provides an estimate only. Actual mortgage repayments depend on your lender, interest rate, loan terms, fees, insurance and other applicable costs.
How to Use the Mortgage Calculator
Buying a home is a significant financial decision, and understanding the likely monthly repayment can help you narrow down the properties that fit your budget.
The Austine Realtors mortgage calculator allows you to estimate your monthly mortgage repayment using four key figures: the property price, your deposit, the annual interest rate and the loan repayment period.
Enter the price of the property you are considering, followed by the percentage you expect to pay as a deposit. Add the annual interest rate offered by your lender and the number of years over which you plan to repay the mortgage.
The calculator will estimate your monthly repayment, the amount you would need to borrow, the total interest payable over the loan period and the estimated total amount repaid.
These figures are intended to help with planning. Your actual mortgage terms and repayment amount will depend on the lender and the financing agreement you qualify for.
How Mortgage Repayments Are Calculated
A mortgage repayment is primarily made up of two components: the amount you borrowed and the interest charged by the lender.
The amount borrowed is commonly referred to as the principal. If, for example, you are purchasing a property for KES 15 million and contribute KES 3 million yourself, the mortgage principal would be KES 12 million.
Your lender then charges interest on the outstanding loan balance according to the agreed mortgage rate.
The calculator above uses a standard amortising loan calculation to estimate the monthly amount required to repay the mortgage over the selected term.
Several factors therefore affect how much you may pay each month.
Property price
The higher the value of the property, the larger the mortgage you may need unless you increase your deposit.
If you are still comparing properties, adjusting the property price in the calculator can help you understand how moving between different price ranges affects your estimated monthly commitment.
Deposit
Your deposit reduces the amount that needs to be financed.
A larger deposit generally means a smaller mortgage principal and, all other factors remaining equal, lower monthly repayments and less interest paid over the life of the loan.
The deposit required will depend on the lender, property and mortgage product available to you.
Interest rate
The interest rate has a significant effect on both your monthly repayment and the total amount paid over the lifetime of the mortgage.
Even a relatively small difference in the annual rate can create a meaningful difference when the loan is being repaid over many years.
When using the calculator, enter the actual rate quoted by the lender you are considering rather than relying on a general market figure.
Mortgage term
The mortgage term is the period over which the loan will be repaid.
A longer term can reduce the monthly repayment because the loan is spread across more payments. However, it can also increase the total amount of interest paid over the full repayment period.
A shorter term generally increases the monthly repayment but may reduce the total interest cost.
The right balance depends on your income, financial commitments, deposit and long-term plans.
How Much Deposit Do You Need for a Mortgage in Kenya?
There is no single deposit percentage that applies to every mortgage in Kenya.
The amount you need to contribute will depend on the lender’s requirements, the value and type of property, your financial profile and the mortgage product being offered.
Before committing to a property purchase, speak to the lender or mortgage provider you intend to use and establish how much they are willing to finance.
This is particularly important when setting your property budget.
For example, being approved for a particular loan amount does not automatically mean that every property at that price will qualify for the same level of financing. The lender may also carry out its own valuation and due diligence before approving the mortgage.
What Can Affect Your Mortgage Repayment?
Your property price, deposit, interest rate and loan term provide a useful starting point, but they are not the only factors involved when buying property through mortgage financing.
Your lender may consider your income, existing financial commitments, employment or business income, credit profile and ability to service the loan consistently.
Mortgage products can also have different interest structures, fees and insurance requirements.
For this reason, the calculator should be used as a planning tool rather than as a mortgage approval or quotation.
A useful approach is to test several scenarios.
For example, calculate what happens if you increase your deposit, choose a slightly less expensive property or reduce the repayment period. This gives you a better understanding of how each decision affects the overall cost of buying the property.
Costs to Consider Beyond the Mortgage
The purchase price and mortgage repayment are only part of the cost of acquiring property in Kenya.
Depending on the transaction, buyers may also need to budget for costs associated with the property transfer, legal work, valuation, financing and other professional or administrative requirements.
These costs can vary considerably depending on the property and the structure of the transaction.
Before making an offer, it is therefore important to understand both:
the amount required to complete the purchase, and
the amount you will need to comfortably service each month after buying the property.
A mortgage may make a property financially accessible, but the full acquisition cost should still form part of your planning.
Should You Choose a Longer or Shorter Mortgage Term?
Neither option is automatically better.
A longer mortgage term may make a property more affordable on a monthly basis because the repayments are spread over a longer period. This can be useful where maintaining manageable monthly cash flow is the priority.
The trade-off is that borrowing for longer can result in more interest being paid over the lifetime of the mortgage.
A shorter mortgage term usually means higher monthly repayments, but the mortgage is cleared sooner and the total interest cost may be lower.
Use the calculator above to compare several loan periods rather than looking only at the lowest monthly repayment.
The total repayment figure can be particularly useful when comparing the long-term cost of different mortgage terms.

Frequently Asked Questions About Mortgages in Kenya
How accurate is this mortgage calculator?
The calculator provides an estimate based on the figures you enter. It does not constitute a mortgage quotation or loan approval.
Your actual repayment may differ depending on the lender’s calculation method, approved interest rate, applicable fees, insurance and other terms of your mortgage agreement.
Does the calculator include legal fees, taxes and other property purchase costs?
No. The calculator estimates the mortgage repayment based on the loan amount, interest rate and repayment period.
Costs associated with purchasing and transferring the property are separate and should be budgeted for independently.
Can I use the calculator before speaking to a bank?
Yes. It can be useful during the early stages of your property search because it allows you to compare different property prices and financing scenarios.
Once you identify a realistic budget, you should confirm the financing terms available to you directly with a lender.
Does paying a larger deposit reduce my monthly mortgage repayment?
Generally, yes.
A larger deposit means you need to borrow less. With the same interest rate and repayment period, reducing the mortgage principal will reduce the estimated monthly repayment.
What happens if mortgage interest rates change?
Your repayment may change depending on the structure of your mortgage and the terms agreed with your lender.
When assessing affordability, it is useful to consider whether you would still be comfortable servicing the mortgage if borrowing costs increased.
Can Austine Realtors help me find a property within my mortgage budget?
Yes. If you already know your approximate purchase budget or mortgage range, Austine Realtors can help you identify suitable properties within that price bracket and preferred location.
