Cumipmt Function
Calculate the cumulative interest paid on a loan between two periods. CUMIPMT is useful for measuring financing cost over selected parts of an amortization schedule.
Cumprinc Function
Calculate the cumulative principal paid on a loan between two periods. CUMPRINC is useful for tracking debt paydown over selected windows of an amortization schedule.
Db Function
Calculate depreciation for a specific period using the fixed-declining balance method. DB is useful when early depreciation should be higher but follow a fixed declining rate.
Ddb Function
Calculate depreciation for a specific period using the double-declining balance method. DDB is useful when depreciation should be more aggressively front-loaded.
Dollarde Function
Convert a price written in fractional dollar notation into a decimal number. DOLLARDE is useful when market quotes must be converted before calculation.
Dollarfr Function
Convert a decimal price into fraction-style dollar notation. DOLLARFR is useful when a decimal calculation must be presented in a market quoting format.
Effect Function
Calculate the effective annual interest rate from a nominal annual rate and compounding frequency. EFFECT is useful when quoted rates must be converted into a comparable annual yield.
Fv Function
Calculate the future value of an investment or payment plan using a constant rate. FV is a core function for savings projections, target planning, and compound-growth analysis.
Fvschedule Function
Calculate the future value of an initial principal after applying a schedule of varying interest rates. FVSCHEDULE is useful when growth does not follow one constant rate.
Ipmt Function
Calculate the interest portion of a loan payment for a given period. IPMT is useful for amortization analysis, mortgage review, and payment breakdowns.
Irr Function
Calculate the internal rate of return for a series of periodic cash flows. IRR is used to estimate the periodic return implied by a project or investment timeline.
Ispmt Function
Calculate the interest paid during a specific period when principal is repaid evenly over time. ISPMT is useful for fixed-principal schedules and comparison against amortized loans.
Mirr Function
Calculate the modified internal rate of return using separate finance and reinvestment rates. MIRR is useful when IRR is too optimistic about how positive cash flows are reinvested.
Nominal Function
Calculate the nominal annual interest rate from an effective annual rate and a compounding frequency. NOMINAL is useful when APY-style rates need to be converted into nominal quote form.
Nper Function
Calculate the total number of periods required for a loan or investment under constant payments and a constant rate. NPER is useful for payoff planning and goal-timeline analysis.
Npv Function
Calculate the present value of a series of periodic cash flows using a discount rate. NPV is a core valuation function for project analysis and capital allocation.
Pduration Function
Calculate the number of periods required for an investment to reach a target value. PDURATION is useful when the unknown is time rather than value or rate.
Pmt Function
Calculate the periodic payment for a loan or annuity with a constant rate and constant payment schedule. PMT is one of the core functions for loan budgeting and savings-plan design.
Ppmt Function
Calculate the principal portion of a loan payment for a specific period. PPMT is useful when you need to see how much of one payment reduces the balance.
Pv Function
Calculate the present value of a payment stream or target balance using a constant rate. PV is a core valuation function for annuities, loans, and discounted cash-flow structures.
Rate Function
Calculate the interest rate per period implied by a payment structure. RATE is useful when term, payment, and principal are known but the financing rate or growth rate is unknown.
Rri Function
Calculate the equivalent growth rate over time. Useful for CAGR-style analysis with clear start and end values.
Sln Function
Calculate straight-line depreciation for one period. SLN is useful when the depreciation charge should stay constant across the asset life.
Syd Function
Calculate sum-of-years' digits depreciation for a specific period. SYD is useful when depreciation should be higher in early periods and lower in later ones.
Tbilleq Function
Calculate the bond-equivalent yield for a Treasury bill. TBILLEQ is useful when a T-bill needs to be compared with securities quoted on a bond-yield basis.
Tbillprice Function
Calculate the price per $100 face value for a Treasury bill from its discount rate. TBILLPRICE is useful when quoted discount terms must be converted into a purchase price.
Tbillyield Function
Calculate the yield for a Treasury bill from its price. TBILLYIELD is useful when the bill price is known and the implied annual yield is the unknown.
Xnpv Function
Calculate net present value for cash flows that occur on irregular dates. XNPV is the date-accurate valuation function for real cash-flow calendars.
