Interest Calculation
Accurate interest calculation for any method — flat, reducing balance, or compound — with schedules generated automatically at disbursement.
Interest Calculation is the mathematical engine inside the YoApp lending platform. It supports all common interest methods used in emerging market lending — flat rate, reducing balance (both monthly and daily), and compound interest — and generates the full repayment schedule automatically the moment a loan is disbursed. There are no manual calculations, no spreadsheet formulas to maintain, and no rounding errors.
Everything you need, nothing you don't
Flat Rate Interest
Calculate interest as a fixed percentage of the original principal — applied uniformly across the loan tenure. Simple, predictable, and widely used for small-ticket lending.
Reducing Balance (Monthly)
Calculate interest each period on the outstanding principal balance — so interest charges decrease as the borrower repays. Standard for mortgage and consumer finance products.
Reducing Balance (Daily)
Accrue interest daily on the outstanding balance — correct for products where early or partial repayments are common and interest should reflect the exact number of days funded.
Compound Interest
Capitalise unpaid interest to the principal balance at defined intervals — used for specific product structures where accrual accounting treatment is required.
Automatic Schedule Generation
The full repayment schedule — principal, interest, fees, and total instalment per period — is generated and stored on the loan record at the moment of disbursement.
Early Repayment Calculation
If a borrower makes an early or partial repayment, the platform recalculates the outstanding schedule automatically using the correct method for the product.
Penalty Accrual
Daily penalty interest accrues automatically on overdue balances from the trigger date defined in the loan product — added to the outstanding balance without manual intervention.
Interest Accrual Reports
View the total interest accrued across the portfolio for any period — by product, branch, loan officer, or individual loan — for management accounting and regulatory reporting.
Built for your team
Implement any interest method your product requires — without a developer. Change the method on a product and the engine handles all the maths from the next origination.
Trust that every loan's interest figures are calculated consistently and correctly — with the calculation methodology stored against every loan for audit purposes.
Receive a clear repayment schedule at disbursement showing exactly what they owe, when, and why — reducing payment disputes and improving repayment rates.
